Just finished getting a furnace and A/C unit installed. Everyone we dealt with was very professional and knowledgeable from Matt who did the consult and quoting , to Eric, Stephen and Richard who did the install. The install was very clean and professional looking and the installers were a pleasure to deal with. I would recommend Delta Air Systems to anyone.

Great, prompt, professional and pain free service.I had my 20+ year old furnace start to give out at the tail end of the cold weather this winter. Delta was able to send out someone shortly to take a look and discuss options which left me confident in what I wanted for a replacement and some useful information going forward.The install itself was equally professional and prompt.Glad I used Delta and would recommend them in the future.

We're been dealing with Delta for a few years now and they've always and still do provide top level service. Sadly this winter our 1979 original Lennox furnace developed a terminal fault and required replacement. Tanya from Sales came to our house to see our layout and existing system and discuss options to proceed. We were given a quote with 4 options to proceed, all included equipment, associated materials including some duct work replacement, parts ,labour and taxes so there were no surprises at the end .The install crew of Kyle & Richard were Professional and knowledgeable and pleasant to deal with,right from start to finish,removing the old furnace and AC to installing new equipment and running new wiring for the new Ecobee etc. Kudos to the whole team at Delta, Many Thanks again.

My daughter was completely satisfied with Delta Air System when she purchased her new furnace last year. The process of obtaining the quote, the price, and the installation were all 5 star!When my son had a possible natural gas leak in his home last month, Delta was the obvious choice to call.Megan was the technician that was promptly sent to my son’s home. She patiently listened to his concerns, asked questions until she was satisfied what all needed tested. When she was finished her analysis, she gave a complete summary, and options for the repair. Happily listened to any questions he had, was able to make a repair immediately.We would highly recommend Megan, as well as Delta!!

We had an excellent experience with Delta Air Systems from start to finish. From when I first reached out, to the actual install, everyone was great! Tanya was wondering and gave us many options to choose from based on preferences and price point. Liam B and Fabio did the installation of our furnace and AC and they were awesome. Arrived on time, they were professional, kind, answered our questions and went over everything before they left. I would definitely recommend Delta Air Systems!!

I was in need of replacing my furnace, and I got it done through Delta. Liam and Eric did the job for me. They were both very nice, skillful and attentive to details. They came in on time and got the job done in a clean and tidy way. I was very happy with the result. I'd highly recommend Delta.

I was a customer with another company before but not anymore i will be contacting Delta moving forward for any of my furnace needs.I had a technician from another company come to my house to look at my furnace as it was not producing any heat and was told i needed a new blower motor but they were only able to source one from the USA and it would be here in 7-10 days. I had been a customer with them for over 20 years and to be honest had never had an issue with them till now.Thankfully Jordan and her team at Delta ( Tyler and Cody ) were able to arrive on site the same day and get my furnace up and running and then return the following day with a brand new motor and have it installed.I would recommend Delta Air Systems to anyone in need of help with there HVAC.

I had an amazing experience with Delta and the team when they installed my new furnace yesterday. The team was professional, friendly, and extremely thorough. A special thank you to Kyle and Richard for their excellent work—they arrived on time, explained everything clearly, and made sure the installation was done perfectly. They also left everything clean and spotless, which I really appreciated.I also want to give a huge shoutout to Tanya, who was absolutely amazing throughout the process. She promptly answered my emails and calls, walked me through all my questions, and provided detailed technical insights into the different furnace options and recommendations. Their transparency and sincerity were truly appreciated, making the entire decision-making process so much easier.If you’re looking for a company to take care of your AC or furnace system, don’t think twice—go with Delta! (I had a terrible experience with Reliance, and this was a night-and-day difference.) Highly recommend Delta for their top-notch service and skilled professionals!

We had been renting our furnace and air conditioner from a different well known home comfort company for 10 years and had finally decided it was time to get out of the rental game and buy a new furnace and air conditioner. So we reached out to the home comfort company that we had been a customer of for the 10 years and asked them what we would need to do to terminate our rental contract and instead purchase a new furnace and a/c system from THEM. They told us that someone would get back to us within 3 days to discuss further. The three days passed, and then 3 weeks passed and finally when 3 months had passed without hearing back from them, we decided they did not want to retain us as customers and looked for another company in town.That other company ended up being Delta Air Systems. We submitted a form online and within an hour, Jamie from Delta Air reached out to us to discuss further. From there it was nothing but very pleasant and helpful calls and email exchanges where Jamie helped us choose the perfect Lennox system. Not only did we get exceptional Lennox quality, but Jamie also helped us choose a quality system that met our budget and price range.Once we finalized on the system we wanted, the Delta Air install department then arranged to have the system installed on the day that we wanted. We subsequently decided to change the install date, and once again the install department was very accommodating and set up the new date for us right away.The weekend prior to the install date we had a massive snow storm and we were certain that Delta Air would either not be able to do the install on our preferred date or would end up putting in the furnace but not the a/c given how cold it was and how much snow was on the ground. But no, that is not what happened.Eric B. and Stephen were the two installers that Delta Air sent out and they were fantastic. Both Eric and Stephen were very professional and pleasant. They were also very hard working and just kept on chugging even though it was so cold and awful outside. On day 1 of the install, Eric and Stephen took out the rental furnace and put it in the garage. Then they took time and care to install our new wonderful Lennox furnace along with the smart thermostat that we wanted. By the end of day 1 our house was nice and toasty with no hiccups.Day 2 was extra cold outside but again, Eric B. and Stephen arrived early and got right to work on the a/c. The old rental a/c was dug out of the snow and in the garage within a few hours and then once again Eric and Stephen took time and care to install our new Lennox a/c even though it was just brutal outside. And just like day 1, they were completely professional and pleasant about it.All in all our experience with Delta Systems was excellent from beginning to end. Thank you to Jamie, Eric B., Stephen and the wonderful people at the Delta Air install department for a very easy and hassle free experience.

Those guys are simply awesome! I wish they can go full service and I will let them take care of everything in my house.My 18 year old furnace finally decided to retire on the first Sunday of Feb when it was really cold and I have young kids. I immediately called four local reputable home heating contractors, including Costco and Delta (It ends up Costco is using Delta, so three). Jamie Hann is the sales person who answered my phone. I ended up deciding to replacing both furnace and AC as a bundle. He provided me options from budget to performance, and was able to educate me the key difference. He was so patient and made tons of quotes for me and also promised me to get the furnace in on Tuesday if I can make the decision before Monday night. Once I decided what I want, I asked all three contractors to quote. Delta ended being 1k+ cheaper than the other guys, which made me a bit worry about the quality of the service.I took a leap of faith and I got a Luxes for the price of a Toyota. My installers are Eric and Stephen. They are nice and patient and answers all my questions. The craftsmanship is supreme. After the installation, the unit fits in as if it were the original. Everything is perfectly measured. No tape at all. They used thick mat for all metal sheet connections not only providing better seal but also absorb vibrations. The way piping, joints and wiring layout are not only functional but also ecstatic. Here comes the bonus - they install a unit so that my HVAC and humidifier talk to the thermostat too. I don't need to manually turn down the humidifier when it is too cold outside to prevent sweat inside of the glass panel. The HVAC will kick in when furnace is up and running to better circulate the air in home. The market value of this unit is about 200 bucks. I never ask for it, it was not in the original quote as a separated item, but I got it with no cost because Delta considers it as part of the "bundle". The system is now truly smart and does everything for me. The furnace Jamie recommended exceeds my expectations too. Now my home is more evenly heated. It is much better than my 18 year old veteran.It is too early to talk about AC I will edit as summer comes.After the installation is done, Eric and Stephen cleaned my basement for any debris. I can't be more happy about it!

Nice guys do doing the installation. Asked how I would like things set up (eg whether the filter replacement should face front or back). Cleaned everything up nicely. Came during the scheduled arrival time, had everything they needed. Walked me through the new thermostat and helped set up the mobile app. Experiences like this are why I've dealt with Delta Air Systems for years. Thanks, Liam and Eric!

My 30 year old furnace finely saw it's last days and Tanya of Delta had me up and running with a new furnace the very next day, she explained the best heating solutions for me to choose from. The technicians Eric and Stephen I found highly skilled and above all calm, friendly and hard workers. They let me know what was happening. Also the clean up afterwards was perfect, Thank you. Special Shout out to Cody for rectifying a major problem within minute's of coming out in the evening on a winters night!I highly recommend Delta Air Systems, you are in safe hands!David-Michael Dunbar

I had an issue with my furnace and initially contacted another company since we had a service plan with them. They said it couldn’t be fixed and needed to be replaced. I then reached out to Delta Air Systems for a second opinion. Everything went smoothly, and the technician, Braedon, was able to check and repair it. He was professional, knowledgeable, and took the time to explain everything clearly. Excellent service from Delta Air Systems & Braedon —I highly recommend calling them for HVAC issues/install.

I got Delta Air Systems furnace installed couple of days ago. They were great with their professional and friendly service. Tanya knew what type of furnace I needed. Installers Eric and Stephen installed the furnace and they explained what they did. Once the furnace was installed they explained how to use the furnace and programmed the new thermostat for me. They deserve a 5 star review.

We had a wonderful experience with Jamie Hann, a Delta Air Systems Sales representative. Our furnace stopped working after 16½ yrs so we needed a replacement. Jamie came to the rescue. He was professional, knowledgeable and confident in the products Delta had to offer. His experience in both installation and sales helped us to make a faster decision on which unit was right for our home. Everything was evaluated and within minutes we had all the information necessary to proceed with the order. The next day, contractors Dan and Richard came out to do the installation. They were friendly, respectful and worked non-stop from start to finish. The job was precise and everything was cleaned before they left. Dan and Richard was kind enough to go through all the details of the new unit. We are grateful Delta Air Systems installed our new furnace with peace of mind. Thank you to everyone!

They showed up when they said they would. I ordered a full furnace inspection & cleaning. Braedon went over everything told me where there might be a future issue ( but not bad enough now). He advised that my furnace was very clean and l didn't need a full cleaning. He charged the base rate saving me $50.He answered all my questions and gave me advice on my water heater maintenence too.I'm very satisfied with Delta. They will continue to be my goto HVAC company.

I’m a lucky home owner that got close to 28 years out of my first new Lennox HVAC system before it gave up. Called Delta after googling local companies online given the last company I used no longer exists. I can see why Delta has high reviews. #1 a person answers the phone. #2 an appointment was booked for a tech to come and see what was wrong. Megan called ahead of time to let me know she was running early. Awesome. Came out and gave me bad/but expected news followed up by Matt in sales that afternoon in person to give me options on a new system. Slept a few days on it while getting a few other quotes and decided to go with Delta. Matt followed up with me via email and phone and was available to answer all questions. Installation of new system was arranged right away being without heat early November I was bumped in priority.Removal of old system and install was headed by Eric’s team. Very personable crew that come across as enjoying what they do and knowledgeable. And if they didn’t know they asked to give me an answer. Slick and tidy installation. Liam went over the “high tech” thermostat and phone app with me and we got it all sorted.Few months later and am pretty happy with the new Smart heat pump /furnace system.

Our on-furnace whole-home humidifier was not working. Worked with Delta Air Systems service to get a good replacement and they installed it next day. Liam and Fabio installed the General Aire 4200PFT. They were polite, quick and professional and did a great job on the installation. They laid down runners to protect our floors and cleaned everything up after. They did a good job of explaining how to maintain it and answered all my questions. Highly recommend.

Liam B and Fabio installed our furnace at the church. I cannot say enough about what an excellent job they did. They arrived on time, and were finished before their estimated time of completion. They answered every question we had in a friendly manor; and when they left, the area they worked in was cleaner then when they had arrived. If someone were to ask me if there were there any problems, I would say, without hesitation, that there was not. I would highly recommend them.

Which Ductless Installation is Right for You?
If you’re interested in installing a ductless HVAC system in your home in the Kitchener-Waterloo, Cambridge, and Guelph region, you’ll be met with two unique and valuable options:
Ductless Air Conditioner
A ductless air conditioner works in a similar fashion to a central air conditioner in its ability to powerfully and efficiently cool your home, however, a ductless air conditioner does not require pre existing ductwork throughout the home to provide cool air. Instead, it’s installed with minimal invasion with one outdoor unit and several indoor registers. Ductless air conditioners individually control the temperature of each room, allowing you to choose your personal temperature preference in each room of the house.
Ductless Heat Pump
A ductless heat pump is very similar to a ductless air conditioner in its ability to work independently from your home’s preexisting (or nonexistent) ductwork, as well as its ability to individually climatize each room of your home. However, the main difference between a ductless air conditioner and a ductless heat pump is that a heat pump has the ability to both cool and heat your home from one system while a ductless air conditioner can only cool your home.
Benefits of Ductless Heat Pumps in Kitchener-Waterloo, Cambridge & Guelph Region
Not convinced that a heat pump is a right choice for your home in the Kitchener-Waterloo, Cambridge, and Guelph area? Before making your decision on what home comfort system is right for you, first consider the following benefits of choosing to install a heat pump in your home:
- One system for both cooling and heating your home
- Extremely reliable, dependable, and easy to maintain
- Very energy efficient, saving you energy costs and reducing your carbon footprint
- Includes the unique ability to choose the individual temperatures of each room of the home
- A quiet, compact, and small system
Financing Options for Your Ductless Installation
A great way to ensure a comfortable budget for your new ductless system is to choose to finance your system with Delta Air Systems and FinanceIt. With options for fair and flexible rates, low interest, and quick approvals, you can easily find the right system for your home and your budget.
