We purchased our high efficiency Lennox furnace and A/C system from Delta Air Systems in 2014 and have been happy with its operation since, except for the flow through humidifier that was installed at the time. We hadn't used the humidifier up until now as it seemed to be wasting a lot of water. When I mentioned this to Jordan at the Delta booth at the local home show, she arranged for a technician to come and look at it free of charge the next business day. After checking the system and replacing a clogged and upside down humidifier pad, the humidifier began to work but still seemed to waste a lot of water. He recommended that we install a water saver switch that would help reduce the amount of water wasted. The next day the technician showed up with a water saver, installed and set it, and verified that it was working. And to my very pleasant surprise, he told me that the cost for all this work, including the parts, was being covered by Delta Air Systems since it had been such a long time that we'd been unable to use it. Thank you Jordan and team for your EXCELLENT customer service.

Waterloo Delta Air Systems is a Top Notch Company! From my first phone call to the completion of our Greener Homes Grant Refund.I called to have our furnace inspected before the winter and was given an appointment immediately. I was very pleasantly surprised when the technician who arrived was a woman!!!! She did a very thorough inspection and discovered that there were cracks in our heat exchange. We would need a new furnace! She gave us the choice of when was most convenient to have her shut down the furnace so we would not be cold.We called Delta and and immediately got an appointment with the sales rep Jason Adlys and he was amazing. He narrowed down the best choices for our furnace and air conditioner. He told us about rebates available. He helped solved problems related to installing new equipment in an old home. Three fellows worked on our house and completed the entire Installation in one day! They also ran into some problems with new equipment/ old house but were able to problem solve and install everything perfectly. All follow up and questions were dealt with promptly and efficiently. In order to apply for the Greener Homes Grant, we given all the documentation and guidance needed.We are very impressed with Delta Waterloo Heating and Air Conditioning Company.John and Margaret Hunking Jan 2023

Our furnace croaked on a cold Saturday in January. I called Delta Air Systems and Zack the technician was at our house in an hour. He quickly diagnosed the problem (motor was fried) and offered to have a new motor installed later that evening. The furnace was 12 years old so he mentioned said we could consider a new furnace as well. We knew it was older and had suspected that the previous homeowners hadn't maintained it as well as they could have so we opted for a full replacement. The next morning at 9 am, Jay was there taking photos and measurements. He fully explained the process and eased all of our concerns. He quoted a great price and offered to lend us space heaters until the new furnace was installed. By 9am the following morning, Julian and Jacob were there installing the new furnace and removing the old one. The entire process was smooth and effortless. All of the Delta guys were extremely knowledgeable, polite and careful in our house. The work was quick and executed with great precision. The house was spotless after the work was done. The furnace is quiet and works perfectly. We are completely satisfied. Delta Air Systems is the best in the business! We will enlist their services for all of our heating and cooling needs moving forward. I highly recommend them.

I wholeheartedly recommend Delta for all of your furnace needs. Their customer service is top-notch, with every employee being courteous and helpful. I had the pleasure of working with Courtney in customer service, who was incredibly informative and promptly transferred me to Jordan, the service manager. They swiftly identified the best course of action to take. The technician, Zach, they sent was highly skilled and quickly resolved the issue. Delta not only saved me time and money, but they have earned my loyalty as a customer for any future needs.

Wish I could give six stars. I couldnt get the guys who installed my unit to call me back. Luckily, the manufacturer (Applied Comfort) recommended Delta Air Systems who dispatched a technician within a day. Big credit to ZACH for being super knowledgeable, helpful and friendly. If management is reading this please recognize ZACH as an excellent technician. Also, pricing was reasonable!

Bought last two furnaces and AC units from Delta Air Systems. Calvin was very professional and knowledgeable. He was very helpful with minor repairs to the heating system (ie. reset breakers etc.) that I have had for the past 10 years. Also, purchased a new heating and air conditioning system for my personal residence. Would recommend Delta Air Systems to anyone looking for a good company who preform quality work.

We have used Delta on two occasions. Each time their work has been exceptional. This time Delta did a complete retrofit (heating/AC/duct work). The guys were professional and worked so hard. We are very happy with the work completed. We would absolutely recommend Delta.

Delta was recommended to me by a friend when my heating system quit. After contacting them Jason came out, looked at my system and made some recommendations for a system that was a heat pump and backup gas furnace.Needless to say it was a bit of a scary experience when I saw the initial price but Jason walked me through the process to get a grant to cover a nice part of it. I did have some doubts and I expressed them to Delta. They understood and wanted me to be 100% sure. I did some research and felt comfortable about the choice.The install crew was Julian and Brad and I cannot say enough good things about them. They had to do a two day install (lots of work considering my old furnace was oversized and stuck in a small area) and were here on time each day. They didn't mind me checking things out and asking questions. When they left the first day they asked if they could leave some stuff in the garage which I appreciated, they didn't just assume it would be acceptable. The next day when they finished you would not know I had work done as every shred of packing materials, old duct work, etc was gone. Very professional.I look forward to dealing with Delta for all my maintenance etc for the new system.

We had our furnace break, but fortunately Delta was quick to respond with a quote and package that fit our needs. The installers, Steve & Brad, were professional, polite and cleaned everything up perfectly. They spent the time to walk through the new furnace and thermostat as well. Great job !!

I called Delta when my mother's furnace stopped working. They sent someone over the same day who was extremely thorough in doing the diagnostics and gave a detail explanation of what the issues were. They offered a couple of solutions and were very honest in their feedback and pricing. In addition, they offered to lend my mother a couple of heaters until the furnace could be repaired. It was a pleasure dealing with everyone at Delta. It has happened that other companies tried to take advantage of my elderly mother. This was definitely NOT something that I was worried about with Delta. I found them to be one of the most pleasant and honest companies I have ever dealt with. I would, with 100% confidence, recommend them to anyone.

Where do I start? Let's begin with Annie and Courtney in the office. Pleasant, polite and completely professional. Excellent people to have as first line of contact. Now, let's move to Zach. He's been doing this for almost 9 years and let me tell you, the man was fantastic. He was polite. He was personable. He was well spojen and he looked you in the eye when he talked to you. Talk about inspiring confidence! He was thorough and explained what needed to be done during the initial visit. When he came back to do the job, you would hardly know he was in the house. I mean, he replaced everything on the furnace and took the time to set things up correctly. We also have this air exchanger that I have never been able to figure out and he's the first person who was able to explain it to me. I have never felt more confident in my home's heating system then I do after the work that Zach did. You've probably heard this before but whatever Delta is paying Zach, it's not enough. This young man is the type of person that any employer would be happy to have representing them to customers.

Jason & Andrew and their team were very professional with their recommendations, install. The office staff were very responsive with booking the appointments. Within 3 days the from the time we got the very compatative quote and complete install. The installation team was wonderful , they respected our home and laid down Mats to ensure cleanliness. Definitely a 5++ star service and highly recommended. Thank you.

Everyone at Delta Air Systems, from initial contact through consultation and installation, was extremely professional, talented and friendly. They made sure that all questions were answered, all work was explained, and any issues were resolved before invoicing us. We didn't feel pressured to buy a specific brand/product and didn't feel pressured to lease/rent vs. buy (which we wanted to do). I would highly recommend Delta Air to anyone looking for an ethical, professionally-run business.

I am extremely happywith the service and professional customer support from Delta Air Systems. Tanya from the sales team was very helpful, friendly and the best sales person I have dealt with over the years. Jason and Andrew worked hard to install the new furnace and cleaned up after they were finished. Tammy from the office was very cheerful to talk to on the phone. She registered the equipment for warranty for me which I really appreciate. Overall from start to finish everything was perfect!

After we learned our AC was broken we reached out to Delta Air Systems. Tanya responded very quickly to our call and arrived at our home within a few hours. During a period of very warm temperatures we had our install scheduled and completed within the same week. Julian and Brad installed the unit with minimal interruption to our day. The end result was a beautifully installed AC unit and some nice conversations with our installers. I would recommend Delta Air Systems to anyone looking for a reasonably-priced and high-quality AC installed by nice people.

Our experience with Delta air systems was great. The salesman Jason was very informative but not pushy at all. We purchased an a/c unit and furnace. Our installation team Steve and Skylar were very professional! Kept us informed as they worked. Overall a great experience! We are very happy with our a/c unit and furnace.

Tyler came by and was able to diagnose and fix my AC within an hour. Was very happy with the level of service provided and how they were able to help me get through the warranty process with the part that failed.Would certainly recommend Delta to anyone looking for an HVAC company.

Probably the best customer experience i have ever had!Had Delta Air systems replace an old water heater, replace my old furnace intakes, repair my furnace humidifier, installed a new Ecobee smart thermostat and some little strange request like installing a custom hatch, cleaning the ac coil and hard wiring a booster fan to the furnace. Special thank you to Tyler and Jordan for taking the time to bring my ideas to fruition, you guys Rock!I really appreciate you guys for pulling everything together in such a short time frame. Huge shout out to Julian and Brad for such a clean, professional installation. I’m extremely pleased with the work, would highly recommend Delta Air Systems. Look forward to doing business with you guys in the near future.Cheers!

We called Delta Air Systems when our 20 year old AC system stopped working. Tanya came to give us a quote on AC and furnace replacement. Tanya was very knowledgeable and explained the new systems clearly, highlighting their energy benefits and specifications for our home. From the three quotes we got Delta's was the most detailed and Tanya provided us with the longest visit, most thorough inspection and explanation culminating in a choice of 4 systems for varying budgets and needs. Installers, Liam and Matt were punctual, respectful (wore masks ), and their work was very professional. Liam explained the rudiments of the new thermostat and Tanya followed up with a thorough explanation of it. Tanya showed us all the bells and whistles of the thermostat as well as the basic options we would use. We highly recommend Delta Air Systems for their expertise and customer service.

Delta responded promptly to my message and arranged a technician to visit quickly. The technician was professional and friendly and answered all my questions. He diagnosed the problem and had the replacement part on hand so the unit was up and running in no time. I think Delta cares about customers experience.

Delta Air Systems was more than helpful and professional when I had to replace my furnace in (late Dec 2021) and my AC unit (July of 2022). Each installation was done by knowledgeable and polite technicians. Co-ordinating the installs was stress free. The installations were done on time and I am very happy with the work. I am glad that Delta Air was recommended to me via my daughter's friend! Thank you Delta Air.

Started with a diligent review by Tanya of the house needs and whether ductless would work. Good quote and follow up...., installation on time and very well undertaken by Jason and Andrew. They were careful, hardworking, cleaned up everything, but also very good at just talking back and forth about how things were going , how best to do this part etc. The installation was completed ahead of time and the results are excellent. No hesitation in recommending Delta.

Our A/C wasn't functioning properly so Delta came out to provide service. The technician was helpful and friendly but unfortunately our 17-year-old air conditioning unit was going to require a $700 repair so we opted to replace the unit instead.Tanya was incredibly helpful laying out our options. Originally we were booked 3 weeks out but we were able to move it up to a few days after confirming the unit. Jason & Andrew did the install and were punctual and considerate (put down mats so the floor wouldn't get dirty, they wore masks when inside the house).

The Delta team just finished installing my new furnace/AC and some new ductwork and I am thoroughly impressed with how clean and precise their work is. All of the lines, cables, ducts, etc. have been run neatly and some of my stuff was even relocated as part of the job (which they didn't have to do!). It was a pleasure dealing with them on all fronts, and our new system has been performing beautifully. I was worried about some of the challenges and complications that come with an older home like mine but they knew what they were doing. Highly recommend!

Excellent service on install - my furnace closet was a bit of a DIY mess (stuff running all over the place, weird foam sealing, dirty condensation pump) and when Delta installed the AC they cleaned it all up, gave me a new pump for free, and everything now looks high quality and professional.A year later the maker of the AC issued a recall on the drain pan of the unit I bought. Delta retrofitted it as soon as the part arrived, no questions asked and no charge! Turns out Daikin had arranged for another repair company to fix it - didn't realize that. However I'm glad Delta did the retrofit as it was a quality job as usual (and they know they're own installs best I'm sure too.)

We inherited a furnace from the previous home owners - last night it started giving us trouble. Called the Delta Air non-emergency line and they called back first thing this morning, dispatching a technician in less than 20 minutes. The pressure switch was having trouble and since the furnace was still under warranty (we didn't know) Delta replaced it with no parts cost. Overall very impressed with quality of service and responsiveness - glad our furnace got fixed on the last cold day of the winter!
