I couldn’t have possibly been more impressed by this company!!! After having two horrific experiences with two companies in Waterloo, the first one being Comfort Air who did a terrible job in trying to fix my fireplace by breaking a unit and keeping the deposit for ordering parts despite the damage they had caused which resulted in me firing them, I learned about Delta Air Systems. I wish I had taken more time to check the reviews online in which case Delta Air Systems would have been my absolute first choice. Nevertheless, better late than never! They are true professionals! They respond to emails and calls in a timely manner, and certainly know what they do when it comes to HVAC repairs. I was actually turned down by a few companies after Comfort Air as no one wanted to fix the damage caused by them. After a few rejections I found out about Delta Air and I was taken GREAT care of! Jordan is the name of the lady who helped me connect with their best mechanic. She was beyond fabulous! Bryan was the mechanic who finally fixed the fireplace. He is such a nice man and so good in what he was doing! All the best. You will be in GREAT hands.

Was really impressed with the installers; the job required a bit of creativity, due to the old furnace, and they consulted me every step of the way to make sure I was happy.

Our experience with Delta Air from quotation to installation was professional and informative. Jordan supplied options and a solution to our Furnace and AC needs and the experienced installers of Julian and Matt completed the project in a timely manner. I highly recommend Delta Air Systems. John A

Excellent Team Work from Delta!! Guy- service tech who checked into problem with AC ( missed the little rat (no problem) but circuit board on furnace was done anyway. ) Josh - sales person who explained all equipment thoroughly. Well done! Tammy - cheerfully scheduling appointments for installation! Matt, Mark? and ———? who completed installation of furnace, air conditioner, thermostat etc. in one very hard working day. And then when the AC wouldn’t start up??? Ben - who came that same evening, discovered that dirty little “fried” rat who had chewed wiring just inside the brick wall?!?!? After exterminator visits . . . FINALLY, great clean up and completion of installation by Julian and Matt!!! THANK YOU!

I am more than happy dealing with Delta Air. I have been a customer for many years, and yesterday they installed my air conditioner. From the very start with a quote from Josh, Tammy in the office, to the very amicable , knowledgeable installers Julian and Matt. I would certainly recommend Delta Air to others.

My AC died one night so the next day I called and got an appointment. Due to the long weekend it was a few days before the appointment but on that day my windows started at 11 and went till 3 and they were there by 11:30.The technician, Guy, was very profession and worked very efficiently. He listened to what I had discovered and tried and didn't then try the exact same thing. He also didn't try to upsell me on anything. My issue turned out to be a blown capacitor. Which he had one of in the truck. The issue was resolved very quickly and he was on his way.I would 100% use this company again for any heating/cooling related issue I have.Keep up the great work.

G'day, my name is Rob, l engaged Delta Air Systems to install a high efficiency furnace and also a new hot water heater. I have worked in the facilities industry for over 40 years and there are probably only a handful of companies who undertake their work so professionally and ensure customer satisfaction as has Delta on this project.I had a couple of problems with a component and an installation, and they resolved them to my full satisfaction. The component problem just would not go away, but it looks like it is now resolved. Thank you for your commitment to your customers, and for the president to contact me to ensure that all was resolved. Wishing you nothing but success. I have absolutely no hesitation is recommending this firm to anyone. Cheers

Delta installed my HVAC system (replacing hot water radiators and installing AC for the first time) and in the 10 years since when it's (rarely) needed service I've always called them. Their installers and service people are skilled, professional, and a delight to have in my home.

We have used Delta to help us when we had trouble with both our furnace and air conditioner. They even installed a gas link on our deck for our BBQ. They have been excellent and I would recommend them to anyone. Their customer service is exceptional and really know how to keep a customer happy. A special shout-out to Jordan for all her help during our initial purchase and follow-up. You rock!

We had a Lennox air conditioner installed May 1st. Vince and Dakota did a great installation job and clean-up. They also thoroughly answered any questions we had and consulted with us when necessary. Thank-you Vince and Dakota! The people at Delta Air have always been great to work with over the years. We appreciate their service very much --- their sales consultation, new furnace installation a few years ago, furnace maintenance and friendly telephone manner when setting up appointments. Thanks to all!

Yesterday, Delta Air Systems installed a new Lennox SLP98V modulating variable speed motor furnace & EL16XC1-030 central A/C with a iComfort S30 thermostat.. John K. did a great job of providing us all the relevant information of systems available from Lennox & helping us decide the best suited system for our needs to complete the order. Installers Vince, Dakota, Shawn, & Matt arrived on time as scheduled, placed protective throw sheets on the flooring & proceeded to remove our old HVAC system. They all worked very well together coordinated by Vince & John K. in completing all aspects of the job. Vince spent time setting up the new iComfort thermostat & instructing us on it’s features & usage after starting up the new furnace. Due to outside temperature the A/C unit couldn’t be finished being set up till later. All the inside & outside work was completed on time efficiently & as ordered. They cleaned up when completed removing all the old equipment for recycling. John K. & Delta are completing the product registration & submitting all relevant rebate paperwork as required. Thanks to everyone at Delta Air Systems, especially to the 4 installation technicians Vince, Dakota, Shawn, & Matt for a job well done & their professional & courteous service along with sales/customer representative John K.Thanks to everyone for making us feel we are valued & future customer of Delta.

Can't say enough about our experience. Josh, Vince and Dakota were terrific. Highly recommend Delta to anyone.
14:06 28 Mar 19
I chose Delta because of the positive google reviews. I am selling my house and my furnace had to be replaced. John helped me get the right product for $1000 cheaper than the next guy! Shawn and Matt installed my furnace as quiet as possible (have a tenant with a new baby). Quality work, great communication and support from Tammy. Choose Delta. Seriously. I'm a VERY picky person when it comes to contractors. (Been screwed over majorly in the past.... never again!)

We recently purchased a new furnace and air conditioner from Delta Air Systems. Received our quote from Jordan on Friday, made our decision Saturday, had our furnace installed on Monday and our a/c installed Tuesday. Steve and Mike, our installation crew, were professional, courteous and friendly, focused on their work and did an excellent job. They put down drop sheets to minimize dirt from their foot traffic, cleaned everything up before leaving, and made sure we were well acquainted with our new systems and thermostat. We can highly recommend them to anyone.
01:16 27 Mar 19
Delta Air is truly a stellar company. They understand what customer service is all about. Last month, I had a new furnace installed after my old furnace broke.Everything went very smoothly as planned, and I would not hesitate to recommend them wholeheartedly!

My wife and I can't say thank you enough for the great customer service provided by Delta. We had a whistling sound coming from our furnace that was loud and driving us crazy. We called another company and after they couldn't figure it out, and after three visits we turned to Delta. The President Kelvin came out and spent a good hour trying to solve it at no charge! He took apart the furnace, had a thorough look and noticed that the previous company hadn't bothered to clean the coils in the furnace after their initial service. As well he noticed that the incorrect motor was installed (by the previous company to fix our issue) and there was an air-flow issue causing the sound. He took care of it all and ordered us a new motor and set up a follow-up appointment. Sean and Scott then came out and installed the correct motor, and resolved the air flow issue! Great job Delta! We won't hesitate to call you again or recommend you to others. Thanks!

Delta Air Systems replaced our old furnace. We are very happy with the entire process. Jordan was our sales person. She was honest and professional and highly efficient. She also brought us very competitive quote. The communication with her was very pleasant. Emails were always answered in a timely fashion. Vince and Mike came and installed the furnace. They were also very professional. They tried their best not to disturb our little one's afternoon nap, which we really appreciate. They protected our flooring and did a very good clean up job. After the initial installation, our furnace fan was making louder noise than expected. I called Delta Air and they sent Vince and Mike to adjust the fan speed from the factory default to a slower speed that is more suitable to our house. Vince went through the manual with us and showed us what he had changed. We appreciate the professional services they provided. Tammy in the office handled our billing and rebate paper work. She was also great. We would like to thank everyone for providing us with quality services.

Unfortunately our furnace gave out last week, a day before the super cold weekend we had. Much to our surprise, John the salesperson was at our house only a few hours after we called. He was kind and professional. We also decided to replace our AC as it was from 1989. Can’t believe our new furnace was installed the next day and they provided us with space heaters to make due for the night. Our service people were fantastic, thank you Steve and Dakota. Overall, even with this unexpected expense, we couldn’t be happier with the service and quality of the products we chose. Thanks Delta for keeping us warm. Would rate higher but 5 stars is the max!! 🙂

I use this company to perform Waterloo landlord inspections for all my gas appliances. Excellent service with very technical teams. When I provided them feedback regarding an issue, they were able to get back to me answers and an solution we are both happy with. Not many companies will open an dialog with you when you just want to provide feedback. I will definitely be recommending Delta to anyone in KW. Thanks again!

If you have any home heating, cooling issues - stop looking and book with Delta - one of the most professional and helpful companies I've had the pleasure in dealing with over the last 20 years living in the KW region. From their sales staff (Jordan - excellent, knowledgeable and professional) to their installers (Vince, Rob and Matt - personable, courteous and doing it right). 5 Stars across the board!

Excellent service. Despite it being December 24th, I still got a warm and welcoming conversation over the phone when I called about my dead furnace. Luckily they had someone available within the hour to come service my furnace. I stuck around while they were working on it, and not only was the technician thorough, but happily explained what they were doing. They then went above and beyond to ensure I got the part needed to get my furnace working again *on the day of*. 110% would recommend.

The service was excellent. The service staff who came to our house explained everything in great detail, and informed us of what our options were, and never tried to push us to commit to a service we did not require. They were honest and extremely helpful and I would recommend this company to anyone needing HVAC repair.

Delta replaced our furnace (nov26th/2018). Sales person Jordan was extremely helpful as we worked through all of the features and options relative to the furnace, thermostat. She also helped us to get the best pricing between in-stock discounts, manufacturer, and government rebates.The install guys Matt & Shawn did a great job. The new equipment was installed and the old equipment was removed without a hitch. At the end of the job you wouldn't know they had been there!All around great job Delta! Thanks.

After 2 different HVAC contractors suggested we couldn't install a gas fireplace in our basement, Josh, Kelvin and team at Delta looked at it and told us it would be a simple and painless process which it was. Josh followed the process through and the install team did a wonderful job exactly as promised. What a great experience!

You never know you need a new furnace… Until you do. Working with Jordan and Calvin at Delta air has made this experience so much less painful. Their expertise, caring and timely delivery meant for a very smooth process. The quick turnaround on installation and the skills of the guys who put the system in Were excellent. A true five-star experience.
04:41 22 Nov 18
I am very pleased with the service you provided me in obtaining a new furnace. Josh, your sales rep, explained everything to me and your installers Dale and Matt worked efficiently and quickly. When they were done with the installation, they left everything clean and tidy. They answered my questions re the new air cleaning system and the new thermostat.

Our furnace would not turn on this afternoon. It tried to fire up three times and it eventually just turned off.(built in safety feature). Seeing how tonight(November 21, 2018) the temperatures are going to very cold I knew that we could not be without heat. So I called Delta Air Systems. It was a very pleasant experience from the start. After I hung up it only took Guy about 30-40 minutes to get to the house. He worked quickly and efficiently and explained things to me as he went. The job took less than an hour.Thank-you so much to Guy and Delta Air systems for giving us back our heat. I would not hesitate to recommend your company to anyone.Stephanie

Throughout the process, Delta was respectful of us and our home. They took the time to make sure we understood how our new Daikin system (furnace, A/C and humidifier) operated, that we were happy with its performance, and how to make our home more energy efficient. The Daikin system we purchased is operating as advertised. We noticed a much more consistent temperature throughout our home since it's installation.

Overall working with Delta for the replacement of my furnace, air conditioner, hot water tank, and installation of a new humidifier was a fantastic experience. John initially came to our house and explained the process to us, provided us with a variety of options, and then very patiently answered my detailed questions and made equipment selection changes to suit our budget and end goal. Dale and Matt installed the equipment in under two days, having to convert my existing furnace and hot water tank set up from draft style venting to power venting. Their work speaks for itself - we are very impressed. Highly recommend this company!

Josh from Delta came and sat with me for two hours answering every question I had about the new furnace I had put in. He was polite, professional and knowledgeable. What more could you ask for?The installers were on time, knew their stuff, and got the furnace installed. It's working great, no complaints.I will absolutely be a return customer to this great business.

15:31 17 Oct 18
Starting with Josh my sales person the whole experience has been great. Josh gave me choices then explained them all in detail. Dale and Matt were an awesome team! They went above and beyond my expectations and were willing to answer any questions or concerns I might've had. Everyone in the region should use Delta Air systems.

I had Delta Air come to our home to do a full inspection and service of our 17 year old furnace. The person who did this job was George, and I can't say enough about how impressed I was with work. He was a very competent, knowledgable and positive person. He freely explained any questions I had and has our furnace finely tuned for another winter. I will definitely be using Delta Air's services again.

I called around for a couple of quotes and Delta sent over Jordan who was easily the most professional and prepared. Jordan took detailed notes on the scope of the work, had a tablet to prepare a customized quote and use for the discussion of the products, she even brought a portable printer! I really appreciated that level of preparation and felt everyone else played it by ear then fed me corporate pamphlets. The absolute BEST thing about Jordan aside from her people skills is that she walked me through rebate programs the other companies were not even aware of to make sure I got maximum value! I had a Daikon furnace installed by Matt and Rob (sept 2018), both were extremely professional in both their workmanship and respect for my home. Matt especially went out of his way to explain the installation and furnace function. At the end I had a visit from the surprisingly pleasant owner to follow up and ensure my satisfaction. Delta is on another level.

Today I was again very pleased with Delta Air Systems, and the AC Technician, George, who came to service our Lennox air conditioner this time. George was excellent! He was friendly and personable, and after explaining to him what I thought was wrong, he quickly repaired our problem by replacing our unit's blown-out/damaged capacitor. So I once again feel I would certainly recommend Delta Air Systems!

Just had my Lennox furnace and AC installed.Amazing service, knowledge, and expertise from start to finish. Very happy with the finished system. Jordan was a fantastic sales consultant. She worked through our options including factory rebates, government/Union Gas incentives and put together the best packages to choose from. The choice was ours and everything came with a thorough explanation to make an informed decision. Tammy was also awesome to schedule our installation appointment with and followed up with a friendly confirmation. We ended up going for a Lennox system which was installed by Matt and Dale. Again, amazing service, knowledge, and expertise. A lot of care was taken to ensure the best installation was performed, not just what was the quick or easy for them. I ended up with an improved furnace layout/footprint and everything very neat and tidy.Nothing was rushed, everyone we worked with took the time to explain everything and offer suggestions not just for the furnace/AC but throughout the house to get the most out of the system for both efficiency and home comfort.To top it off they handle the mail in rebates and warranty registration to ensure nothing is forgottenDelta has a top notch team of experts

We can not say enough about the incredibly positive expience we had with Delta Air Systems in Kitchener. The quoting process with Josh was smooth and easy, the result of which was an easy desicion to choose Delta. The installation team was awesome, Dale and Matt (with a little help from Scott and Brad later in the day!) were there promptly on the scheduled morning and carrried out the installation in a tidy, considerate and professional manner. We were included in any desicions that had to be made on-site and were given a thorough orientation on how to best use our new ductless AC unit. I highly recommend Delta Air Systems!

Another great job!! We started using Delta Air Service almost 20 years ago. They put a new furnace in our old house and provided excellent service. So, when our new house ever needed hvac service we called Delta. Today they installed a new furnace and ac unit for us. First off, the sales rep Josh was terrific. He walked us through our options and explained available government rebates. Today the crew, Scott P, Shawn B and Brad C came to our house. They were prompt, courteous and professional. They treated our home with respect - even down to arranging the landscaping rocks around the new pad foundation for the ac unit outside. I cannot say enough great things about this company. For 20 years they have provided great service to us. We are grateful for the their commitment to customers. One time we had a tech come out to service our old furnace in the dead of winter on aSunday. Delta Air Systems truly puts customer service first.Their prices are competitive but price shouldn't be the deciding factor. This company is run by good people who employee good people. I would not hesitate to recommend them (I guess that's obvious!).

So happy with our furnace and A/C install by Delta Air Systems when our A/C broke. From the get go, we had a great feeling about Delta. Jordan was our sales consultant, she spend over 2 hours answering every possible question we had. It made the choice to go with Delta so much easier. There were no sales gimmicks, just honest, good advice. We just got the A/C installed by Dale, Vince and Matt today. They were super professional. After the install, Dale and Matt gave us some great tips for saving electricity and made sure to answer all the questions we had. The place was spotless too! Thanks so much you guys!!

Very professional. Identified potential issues with the location of my hot water heater and the furnace before providing me the quote; none of the other bids identified this issue. When I questioned the other bids, they returned, re-measured and admitted that their bids would need to be revised as they did not anticipate the issue. I went with Delta as they identified the issue immediately. I'm very happy with the system and service. I would recommend considering this company.

Delta Air Systems Ltd. recently completed another HVAC project at our home. We selected this firm because they had successfully completed two challenging HVAC projects at our residence a year ago. Delta had earned our confidence with their previous work and we were not disappointed with our decision to grant them more business this time. The work was accurately specified, fairly priced and the execution of the job was first-class. The installation crew was highly experienced and capable, worked very efficiently and cleanly and left the job site in perfect condition. They took the time to fully explain proper operation and care for the equipment. Our sales representative also came by the job site to ensure the project got off to a great start. All in all, we are very pleased with the outcome. We would not hesitate to utilize this firm again and recommend them very highly to you.

I purchased an air conditioner/furnace unit from Delta three years ago. I found their service extremely efficient and cordial. Last year I signed up for the planned maintenance and the yearly appointment was scheduled and executed efficiently and everyone I dealt with was very helpful. I have now run into a problem with my air conditioner and within 24 hours I have an appointment for an emergency service call! Thank you to Laurie for taking care of my problem so quickly and thanks to the technicians for looking after this issue.

The technician, George, was very helpful and informative. He was able to come on the weekend at a time that was convenient, and was able to fix the problem quickly. Wouldn’t hesitate to call them for help again!!

Top-notch service from our first meeting with Josh, to install (Lennox heating and A/C) and sign-off with Dale, Matt and Vince. The crew was exceptionally careful and courteous, and it looked after small stuff we had overlooked (a neater re-routing of piping to the drain). Dale meticulously went over the details of the new thermostat. The system works perfectly. It feels like we're living in a different house.

First class service. Very polite, efficient, friendly and thorough. They were asked to redirect some of our air conditioning. Didn't leave until they checked with everyone to see if they were now more comfortable. Thank you

Our experience from start to finish was first class and professional.Our Central Air conked out during heat wave but John was available immediately to review our needs, and to arrange a quick install of a new unit.Tammy was very helpful with the booking process and ensuring the install team would be available ASAP.Scott and Brad were perfectly on time, immediately started the removal and replace process, but were very helpful in answering any and all questions. A small noise glitch that was detected was corrected without hesitation, and they ensured we were satisfied with the unit before leaving our premises.Kudos to the whole Delta team, you made a bad situation into a great experience, and always with a smile.

The HVAC industry has so many bad apples, you have to give a big SHOUT OUT to the GOOD ONES! Jordan and Delta are the only ones to trust. We bought a new AC and the sales and installation were all top notch. Steve and Shawn were great installers, and happy to say that Steve knows the right way and the wrong way to do things, and that the right way doesn't have to cost a lot.

We have been a long time customer of Delta Air Systems. The biggest things that homeowners need to consider is service after the sale. Delta has been consistently responsive, quick to arrive and is always fair with the repair estimates and the execution of the repairs. Our last experience was with our 17+ year old A/C condensing unit. We expected a big repair bill as we thought that the compressor was done. And, of course it failed just before the hottest long weekend of the year. Left a message in the evening, called back @ 7:20AM the next day, service man on site by 9:15 AM and repair completed by 10 AM! Cost of parts <$20 + one hour of labor! How could anyone not see this as superior service! Thanks Delta!!!

Just had our new Delta Air Systems AC installed this week in time for the next heat wave. From the initial meeting with Josh to the installation process , the Delta team has been fantastic.

We replaced our furnace and AC last week, this is the second furnace in the last few years from Delta (at a different property ) from my first call Delta staff was great. Jordan is a pleasure to deal with she had a great presentation and best price , Dale and Matt did a perfect install, couldn't have done it any better myself.. All around it was a good experience.John and Patti

The entire experience with Delta was exceptional from the first contact with Jordan Wood to the installation. She was very prompt in setting up the initial appointment. I had researched a couple of HVAC installers in the area and found Delta to have the best reviews online. I did talk to 6 installers in the area and Delta had the best quotes.Jordon went over all the options with Lennox and Daikin. I was really impressed with her knowledge of the products offered and the government rebates. She also offered a lot of good tips on the Union gas audit and recommended a auditor who did a great job of walking me through the audit.She was very professional and even carried a portable printer which is better than the handwritten information most HVAC vendors provide. Subsequently all my questions got very prompt email responses and i was able to get an appointment a week after my audit. Considering my Air Conditioner was broken, i really appreciate the quick turnaround.On installation day, Jordon Wood was around to make sure there was no issues and things were of to a good start.The install was done by Vince, Matt and Rob. They were done by the EOD. They did a very clean job. he installers were great. They arrived early and took a lot of time at the end of the day to show me the whole installation,They kept us informed all the way and were very patient with all of our questions.They registered at the manufacturer for warranty and the IESO rebates.Thanks to Jordon, Vince, Rob, Matt and every one at Delta.Definitely recommend this company!

We purchased an air conditioner and Furnace from Delta Air Systems and we cannot express enough how pleased we are with our experience with them. Josh, their salesperson came to our home and went through the options that would best suit our needs. He was extremely knowledgeable, personable and we appreciated that he was very transparent (we had done our research beforehand) about the various products and prices. No BS! That's what we were looking for. They were very good at getting us scheduled in during a very busy time and communicating about timelines. The installation crew, Dale and Matt, were beyond amazing. Matt worked very hard at creating a clean and aesthetically pleasing spot for our air conditioner. They both worked well within a tight spot to install the furnace ensuring that all the lines were seamless. Dale was an incredible, patient and competent instructor of our new high tech system and its applications. Tammy, who works on the rebate and administrative side of things has been very diligent about getting our rebates in motion, we dont have to stress about a thing! DAS is amazing, we are so happy we went with them!

Their Service technicians we very prompt, knowledgeable and friendly. We would never hesitate to refer these guys as they went above and beyond to provide us with exactly what they said they would! No question that we will use them again in the future. Two Thumbs Up! Thanx again to the whole crew involved at Delta Air Systems.

We have just replaced our old Lennox furnace and AC (almost 30 years old). John Kroisenbrunner was Delta representative who came to our house and helped us to select a suitable replacement. He took care of all of the paper work related to applying for government energy efficiency rebates and organised an energy audit. Few days later Paul and Liam installed our new furnace and AC. They did an excellent job and left the place spotless. We are very happy with the service we received from Delta.

Just this past week, my husband and I had Delta Air Systems install a brand new Lennox air conditioner in our home. We knew from the initial visit that dealing with this company was going to be a great experience. Vince was the gentleman who came to our home to talk to us about the a/c and he was so knowledgeable and detail oriented….he wanted to ensure we were getting the RIGHT equipment for our home and that it would be installed according to OUR home’s requirements! On the day of installation, Dale and Matt came to do the job. They were so professional, polite, respectful, laid down their own mats and runners so as not to dirty our floor. It must have been 90 degrees that day and they wouldn’t even accept water from us because “they bring everything they need for the day”. Wow! What a couple of great guys! A few days after installation, we received a follow-up call from Vince to ensure everything was running smoothly and we had no problems! Everything was just perfect!! The whole experience was just so darn easy! And that put a smile on our face! In a nutshell….they are really, really, REALLY good at what they do!! We would have them in our home again in a heartbeat! HIGHLY RECOMMENDED!!

Delta Air systems was recommended to us by my friend Joe, and we were not disappointed. Spencer explained everything in a way that we understood fully and made our choice of a Lennox Elite system.Dale and Matt were our installers. Their experience shone through as they worked. They were both skilled and professional in the way that they did the job. They explained what would happen and they finished in the time that they said that they would. When you purchase a furnace or air conditioner from Delta be sure to ask for Dale and Matt.

I have been a customer of Delta Air Systems since 2011 when I purchased my Heating / Cooling system. Since then I have had my equipment serviced by them and approx. 1-1/2 years ago I signed up for the maintenance program. By doing so I have my equipment scheduled in advance by the service department who are very proactive in contacting me in advance to schedule my service appointments. I also have the option of making a small monthly payment that covers my two maintenance calls annually. In addition my furnace & A/C continue to be covered under warranty as a result of the maintenance program.Recently the service department went above the call of duty to assist me in solving a question I had with my thermostat. As a result I now have a better understanding and resolution to my concern which I greatly appreciate.With the Heating & Cooling system having such an important role in the comfort of our homes and something we just take for granted until something goes wrong, I now have peace of mind knowing my equipment is scheduled & checked over annually to keep things running the best it can. The staff is very professional & helpful and I 100% recommend Delta Air Systems.

We have had really great experiences with Delta.Firstly, they came highly recommended to me by my very discerning neighbour after he replaced his A/C.When our A/C needed to be replaced last summer, I was very impressed with the candour of the Delta rep. At the time he talked to me about getting a new furnace as well, quoted some prices, but did not make me feel obligated or pressured in any way to buy one at that time. At the end of this past winter, our 25 yr old furnace also kicked the bucket. I called Delta immediately and was able to get both a service rep (to evaluate for repairs) and a sales rep (to potentially replace) and they were both able to make it to my house *that morning*. I definitely felt like both service and sales were operating with my best interests in mind. The repairs would have been costly, so we looked at new furnace options. Pleasantly, the quotes I received at this time were well in line with quotes I had received a year earlier. It felt clear to me that my immediate need for a working furnace was not impacting the quotes I was receiving. The sales rep Josh patiently answered all my questions and made sure to point out everything optional in the quotes he was giving me, so I did not feel up-sold.All said and done, we had a new furnace installed the very next day, on budget, and we're also well on our way to taking advantage of some ontario energy saving rebates. The installers were great. They arrived early so that they would arrive before we left for work and took a lot of time at the end of the day to show me the whole installation, and everything that had been replaced or changed. Thanks to Josh, Matt, Dale and Guy and every one at Delta.

From the time that John came into our home to the time it took for Dale and Matt to complete the installation we were totally impressed. They showed up on time and worked very hard to get the job done. Very very professional and they knew what they were doing. There was no pressure from our first meeting with John. John worked with us when we ran into some other issues that needed to be completed. John even came out to check on the work and to make sure we were satisfied. Can't say enough about Dale and Matt...what a team! Professional and respectful. They kept us informed all the way and were very patient with all of our questions until we understood the whole process. I would rate this company and their crew 10 out of 5. Very very pleased!

Excellent company and employees! Customer service is very important to me. I spent a lot of time researching many companies in the area to provide the services I required (new furnace & ac and ongoing servicing). Delta delivers excellent service every time! All employees that I've interacted with (sales, installers, inspectors and office staff) are very knowledgeable and professional. Service is always prompt and courteous.

Several months ago we had DELTA AIR SYSTEMS quote on a home heating, humidification and inspection project in our recently purchased mid-century modern bungalow.From the beginning DELTA provided "on time, on budget" service as well as first rate professional workmanship during the installation. The people were great to work with as they not only talk the talk...they walk the walk.We highly recommend DELTA if you are considering an HVAC project.After all, purchases of this type are typically high dollar investments and demand "word of mouth referral" to safeguard your purchase.Wayne and Deborah in Waterloo

I had them replace my A/C unit when it died. They were very professional (both the installers and sales/business people) and ready to work with me to make sure I was happy. When my furnace died a year later, I also called them. They were not the cheapest quote I got, but close. I felt the extra money was well spent because they did a beautiful job. No regrets working with them. Great service. I plan to have them do my water heater in the near future, too.

I called Delta Air Systems for a technician to check and fix my furnace when it wasn't working properly during a cold spell. The technician came at the time they said, and quickly diagnosed the problem. Unfortunately, the furnace had two major components failed and wasn't cost effective to fix. Delta sent a sales person that evening, who spent the time needed to go over all the options, and walked me through the process to choose the right equipment for me, with no pressure. The installation was scheduled for two business days later. Delta offered to lend as many space heaters as I needed until the furnace was replaced. The installers were professional, didn't cut corners, and did a neat job. After, they made sure I understood how everything works. The sales person followed up a few days later to ask if I have any questions and make sure everything was working property. Overall, it was an excellent experience, and I am extremely satisfied with the professionalism and workmanship.

Wish there were 10 more stars we could check off for the folks at this company. From our initial in home consult with Spencer to the installation team headed by Steve (all of whom had to work hard together to plan and install not only a furnace humidifier but upgrades/rebuilding of parts of our older furnace to both accommodate the new piece of equipment plus update things for a new furnace down the road) and the office staff too....each and every one of them were amazingly friendly, helpful and knowledgeable people who went well beyond the norm in leaving us with a top quality job done and a sparkling clean furnace room at the end. SO satisfying to find a company that not only takes pride in its work but also genuinely cares about its customers' satisfaction. Thanks all!

Delta recently installed a new furnace for my son. His existing furnace quick working. Ryan showed up within hours of his call and determined the Heat Exchanger was gone. We called to get a quote on a new furnace. Spencer met us that night and provided a quote. The estimate to replace the Heat Exchanger was sent the next morning. We decided to purchase a new furnace. Two days later it was installed. Everything from the installation to the correction of some unrelated items was completed above and beyond. Dale and Matt were the ultimate professionals

Delta Air Systems crew, Dale and Matt did a bunch of work at my new house. They installed a new furnace, new ac, new hot water heater and a ton of gas plumbing. The gas manifold is a thing of beauty! Dale and Matt were very professional and respectful of myself and my home. When the job was near completion, Dale explained how everything worked. There should be no problem with me changing the furnace and humidifier filters and programming my thermostat through wi fi and if there is I can ask for help. Great job Delta Air Systems! The basement is where I begin my tour when showing off my new house.I highly recommend Delta Air Systems.Yours sincerely, Carol D.

I couldn't be more thrilled with the work that Delta Air Systems did recently in my house! They installed two gas lines, ran new ductwork, including having to drill through a thick foundation wall to get heat to a new kitchen renovation. They did this on a tight timeline with a reasonable cost. They even fixed a few other 'bugs' with my heating system at the same time. This is a highly professional and knowledgeable company and all the workers were friendly, skilled and efficient. I would recommend Delta to anyone.

I just had an emergency situation with my parents furnace. They live in Kitchener Ontario. Myself living in Toronto I skimmed through online reviews to find an hvac company that could get to them asap ( my parents being elderly). I never thought I would get the exceptional service I experienced. Not only did Delta air systems send a technician out the same day but they resolved the issue. Ben was there in a blink and within an hour had them up and running and if that wasn't amazing enough I then received a follow up call from their protection plans coordinator Laurie she was so helpful and gave me peace of mind she offered a protection plan that includes maintenance and labour coverage so that in the event this happened again my parents are protected ( this is priceless to me).This company is far superior to others after years with other companies even my parents are impressed. Our family will never call another company again you've got customer's for life! BIG thanks to Ben for the repair and to Laurie for your knowledge , time & patience and to the rest of the Delta team!

We moved into a new home and needed a new Furnace & AC installed. I knew immediately I would be calling Delta Air Systems as they did the install of our Furnace & AC at our previous home. Spencer came to our home and spent a lot of time measuring and looking over what we currently have to make sure we didn't end up with any hot or cold spots. He recommended we size down on both the Furnace & AC as the ones we currently have were far too big for our house. After providing us with three different options to choose from he left instead of pressuring us to make any decisions right then and there. Once we made our selection we had someone calling us within 24 hours to schedule the install for the next week. The two installers who came (I'm so sorry I forget your names!) were great. We were told it would take 1.5 days to complete the install but they were done in just 1 day (which included some custom duct work due to a really silly setup from the previous install!). Our house is so comfortable now that it's getting cold out. We have a 4 level backsplit and there are no cold spots anywhere in the house, it's amazing! We are so happy with our purchase. I will always recommend Delta to anyone looking for a new Furnace or AC. Thanks again!

I needed to have my furnace serviced and my work colleague recommended Delta, as our company uses them.Chris was prompt, polite and professional.

During one of the few hot spells of the Summer, our aging air conditioner gave up. Jason was prompt in responding to our call, punctual in meeting and knowledgeable to help us navigate the balance between available rebates, energy efficiency and simply getting the right unit to meet the needs of our home. Jason even provided a hand drawing to describe the work to help us better understand what to expect. Delta also assisted in replacing some shoddy DIY work that had been previously done and needed a professional touch. The installation with Matt and Shawn went smoothly and was very tidy with nothing left for us to do but turn on the new unit and enjoy the cool temperatures. Thank you to the team at Delta for your excellent communication and professionalism.

The installation crew were friendly and did amazing work. Thanks!

Thanks to Delta Air Systems for the installation of our new air conditioner unit in June 2017. We are very pleased with the service and care we received from end to end. Starting with Spencer, who worked hard to get us a system (Daikin condensing unit and Aspen evaporator coil) that was properly sized for our home at a price we could afford.On the day of the install, I was very impressed with the attention to detail, cleanliness, and friendliness from Steve and Jeff, Delta Air installers. The answered all my questions, cleaned up all the boxes, and did a great job with the installation.I will not hesitate to recommend Delta Air Systems and their team in the future.

Highly recommend this company to anyone seeking install of a new furnace, air conditioner or service of an existing unit.Our relationship with Delta started when our furnace broke. We contacted the company who installed the furnace, and they advised we needed an entire new unit. After calling Delta for a second opinion (based on Word of Mouth recommendation), the owner of the company, Calvin, called us to advise the unit was still under warranty and dispatched a technician for repair immediately.When we were ready to install an air conditioner, we did not hesitate calling Delta Air systems. Spencer came to our house, and gave us three quotes. He was very thorough and knowledgeable, and was able to answer all of our questions. As an air conditioner is a large investment for anybody, we wanted to make sure we understood and we're getting the right unit. There was no pressure, and we took a day to decide on what we wanted.The installation happened on the day as scheduled, and Dale and Matt arrive to install at the exact time we were told. They were both very friendly and explained all the work that was going to be done. When extra noise was going to be made, Dale came upstairs to let me know as we have a newborn in the house. I thought this was very courteous. After all the work was done, they gave me a complete tour and explained everything, leaving me with no questions to ask. The unit on the exterior of the house looks great, and all wires and cables are neat and tidy. It's obvious that they are both very experienced and knew exactly what they were doing.So far I was completely satisfied, but what happened next blew my mind. Dale rewired our furnace to ensure that it ran more efficiently, and even fixed the furnace humidifier that we thought was completely shot. He labelled everything for us and organized all of our booklets and paperwork in a document holder right on the furnace ductwork so it's easy to find. Not to mention, all this extra work was done at no extra charge to us. It's really refreshing to work with people who actually care about the clients and want the best for them! We aren't just another air conditioner sale, we are a family that Delta wants the best for.With a newborn child, it is great to now have peace of mind that the climate in our house is controlled and appropriate for good health. Thank you so much to Spencer, Dale and Matt at Delta Air systems for your amazing service, caring attitude, knowledge and time. It's great being a customer of a company that is family owned, as opposed to a mega-corporation who only cares about the bottom line and a new sale. We will definitely recommend you to anyone! Now bring on those crazy-humid days in July!

Excellent experience from end to end. After having two other "leading" HVAC companies try to sell me systems larger than I needed, for thousands more than I needed to spend, Delta was a breath of fresh air. They volunteered making extra duct-work at no extra charge, took the time to do the job properly (2 full days at my house, super neat/clean wiring and other work everywhere), and cleaned up everything before they left. I've now got a great Lennox HVAC system, and most of the time the cooling comes from a return air vent they installed in my basement and I don't even need to use the A/C, just use the furnace fan to move the cold air from my basement to the rest of my house - their idea!

We just had a new furnace and air conditioner installed by Scott and his great team. They worked through the pouring rain to make sure they completed the installation in one day and did a amazing job! If you are looking for a great system give Scott Padfield a call you will be Happy you did! He gives you plenty of options to suit all your needs and price points.

Definitely recommend going with Delta Air Systems if you are in the market for a new furnace or A/C unit. Working with Spencer from their sales department has been nothing but top notch! Had a new furnace and A/C installed by Delta today and the installers were very professional with a high quality of workmanship very evident in their installation. All though there are companies out there that will offer you a cheeper price, you definitely get what you pay for if you choose to go with Delta. Great job Spencer and your co-workers! I will definitely be recommending you to family and friends.

These guys are the best! Since we first had to replace our A/C unit about 10 years ago and the experience we enjoyed, no one else has touched our mechanical equipment. We were referred to Delta by friends and from the first contact with Vince they won and earned our business. Scott Padfield was the salesman and his knowledge and honesty really put us at ease. His follow up surprised us when he did what he said he would do, when he said he would do it!The crew that installed our equipment was professional, courteous and on time. The were clean, efficient and very thorough. On a cold December evening a few years later, our furnace was shut down due to an inspection that found a crack and required our gas be shut off. No worries, Scott was there, less than 10 hours before I had to fly out of town on business and the next morning, at 08:00, as promised the crew wants there to install the new system including humidifier and air cleaner with a programmable thermostat. Again, courteous, clean, efficient, professional, pleasant and bang on schedule. As fate would have it, our Air Exvchanger died a few years later. Without hesitation, call Scott and he was with there to solve the problem. A new system has been installed and works like a charm, as promised.These guys are true to their word, stay on budget and their service is excellent. After some recent home renovations we had to locate controls and this caused some equipement issues. Again, one call and Delta had a technician out who corrected the problem and had the systems running in no time. Their service is great and the technicians are all very professional and pleasant.If you need new mechanical equipment and recognize quality, or need someone to service your equipment properly, save yourself some time and trouble and call the gang at Delta. From the moment they answer the phone you will know you're in good hands.

Furnace stopped blowing air. Called them. Technician was here the next day as I requested withing time frame. After 2 hrs of inspection got a quote for a whopping $770 to replace the control board and labour. I decide to go ahead with it. The technician named GUY left to go get the part and was back in no time. When he tried turning the furnace on with the new part it still didn't work. He went outside and cleared some blockage in the intake pipe with his screw driver and sure enough it fixed the furnace. Could have still charged me $770 n ripped me off if they really wanted like many other companies do I bet but they didn't. GUY explained to me what the problem was and charged me only two hours of labour instead of almost $800. More than reasonable in my eyes. I appreciate their honesty. Happy with the service and will call again if needed and recommend Delta to others.

My wife, and I finally decided to go ahead with our dream of a master suite addition above our garage. Based on our experiences with Delta Air at a couple of our rental properties we invited Scott to evaluate the existing HVAC system in our own home. He could have talked us into a new furnace, and AC unit but happily he reported that the furnace was adequate for the additional square footage (huge savings!). Unfortunately the existing AC unit would not be sufficient. Instead of installing a new AC on the furnace he suggested a ductless heat pump for just the addition. I doubted him but he educated us on the limitations of a system in the basement providing the comfort we want in our new master suite. I was worried the system would be loud (similar to unpleasant hotel experiences) but he assured me it would be very quiet, more efficient, and much better value for money than any other option. I had the privilege of meeting the professional install team of Steve, and Jeff who installed new duct work from the furnace to the new addition and did a great job (They were more than happy to to accommodate our ever changing minds!). However, the star of the show was the Dakin heat pump they installed above the ceiling of our walk-in closet that is ducted to our master bath and bedroom. We couldn’t be happier! It is quiet to the pint we don't hear it, and allows us to keep our bedroom just as we want it. We can close the door and keep the house at one temperature and our master at another. No need to waste energy cooling the master suite during the day. For professional, and honest advice on how to deal with an addition or expansion, call Scott and Delta Air Systems.

We had an unexpected dealing with Delta where they were working with our neighbours house and noticed our furnace exhaust pipe had broken off the side of our house. It was inspected and found to be leaking CO into our basement. It was fixed there and then. Ryan is the representative that we dealt with: very professional. Thanks again!

This company has been a pleasure to deal with. All the people I have dealt with at Delta from office staff, installers, sales reps and service reps have been extremely friendly, knowledgeable and professional. I even received a significant discount on my most recent install simply because I have been a loyal customer. They show up on time, do quality work with no surprises and leave the place clean and tidy. I would not go anywhere else for my heating and air conditioning needs and I recommend anyone reading this review to strongly consider this company when considering which heating and air conditioning company to choose. They really seem to care and appreciate their customers.

When our 24-yr old furnace died in November, Scott Padfield arrived the next day and provided the best recommendation for our home (not the most expensive). He took time to review our options, explain the pros and cons of each, and answered all our questions.The installation team was on time, efficient, clean and professional.We had heat restored in a matter of days.Scott's service was so good that we called him the following summer to install A/C in our 150-yr old home. Scott again made recommendations that preserved the old character & feel of the home, while keeping us cool.Thanks to Delta we're comfortably warm and cold 12-months of the year.

Two installers arrived Monday morning. It took most of the day to install. That included a liner for the water heater. I never knew there were so many things involved with an install. We are happy and satisfied with our new super quiet and efficient Lennox furnace. Delta always came through for us when these other pirates let us down. Delta rules

I had an issue with my furnace related to airflow that I couldn't figure out. Delta installed the furnace in my residence just before I bought the property so I called the number on the label and got connected with an after-hours service rep. The rep was absolutely top notch and he walked me through correcting the issue over the phone which turned out to be a bad (brand new) filter that was impeding airflow. He also called me back an hour later to double check and make sure everything was still ok. This experience came with $0.00 in billable service and I can tell you that this left a lasting impression with me. This how a business attracts and retains customers as I've now recommended Delta to numerous friends and family members who have since done business with Delta as a result. Great customer service NEVER fails.

We recently had to replace a tired, cranky old furnace that had been threatening to call it a career, over the last few years. We had used Delta Air Systems to service our old furnace and were very pleased with assistance they provided to get the heat back on. So they were the natural choice to install a new furnace. Scott Padfield helped us select the furnace and support equipment that has made our house the most comfortable it has been in many years. The installers, Dale and Matt, were true professionals and took the time to explain and answer questions as the install progressed. I can highly recommend the Delta Air Systems team.

We had an excellent experience with Delta Air Systems. After getting a few quotes in the Fall of 2015, we decided to hold off on a new Heating/Air system for the time being. Unfortunately, our furnace quit working in the middle of January 2016.We had already decided to go with Delta as their quote was competitive and Scott went above and beyond with suggestions on how to improve our system, however, we were pleasantly surprised that the quote remained the same when we were in a "need it now" situation.We gave the go ahead and within a day our new system was installed.My wife was quite pleased with the installers. She said Steve and Jeff were very professional and left the house very clean after the work was done.We would not hesitate to recommend Delta to all our friends and familyGreg Hislop

Fast, affordable (for the area), and quick and easy installation. They even cleaned out my wall full of squirrel poop and replaced the eaten insulation when they were installing my new furnace! Definitely recommended.

From our first meeting with Scott to the completion of the installation of the furnace and heat pump, we found the whole experience to be very professional, informative, prompt, and fulfilling of our expectations. We are particularly pleased with the comfort level in our upstairs addition with the heat pump supplementing the furnace. We look forward to a much more comfortable air-conditioned summer upstairs too! Thanks to Scott for this great idea and to the installers for their helpful, clean, and timely work! It was truly a very pleasant experience dealing with all of Delta's employees - we highly recommend this company!

Our air conditioner quit working and after making several calls to various local companies for prices to replace our existing unit, Scott from Delta Air was the only company that took the time to visit our home and quote on a new system. Scott is very knowledgeable, friendly and polite and made suggestions on several options and prices that would meet our needs.Installation mechanics were right on time, competent, respectful of our home and very friendly. Took less than a day to install. Two days after installation was complete I needed to use the heat pump on our A/C and was impressed with the quietness of the unit and the amount of heat we got from it. We are very happy with our new Daikin Ductless split air conditioner and heat pump and the installation. We highly recommend Scott and the staff of Delta Air Systems.

Great service from Delta! Our 3 year old furnace wouldnt start up tonight and the house was getting cold (-15c outside!). I called the service number and left a message. I was called back within 10 minutes and explained the problem and error code to the technician over the phone. He arrived within an hour and came prepared with the part (pressure switch). He had the new part installed, and the heat running within 20 minutes. The technician was friendly and quiet (sleeping kids) and very efficient.Best part was that it didn't cost me a thing! Part covered by warranty and service call paid by Lennox!Great experience....I was pretty stressed out when the heat wouldnt come on in the middle of winter, but within 2 hours we are up and running!

Very professional and fast installation of some very difficult basement duct work where space was very limited. They completed the task in less time then expected, and we still manged to keep our bulk heads tight maintaning a useful ceiling height. Built to code and to satisfaction.
