Liam B and Fabio just completed the replacement of my 25 year old furnace and AC unit. They were both a pleasure to deal with and I would highly recommend Delta Air Systems for your HVAC work. These two installers were quick, pleasant and well prepared.

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 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!

I recently had to replace the furnace in my home and decided to go with Delta for the job. The experience has been excellent.

The initial consultation with Matt was pleasant and thorough. I received several options with competitive quotes and was able to pick the one that best suited my needs and budget. Tammy coordinated the installation quickly. The installation process itself was fantastic. The crew, Kyle and Richard, showed up right on time and were able to finish up everything in about 5 hours: old furnace was taken out, new furnace put in, and the work area was cleaned up. They were very professional and courteous all throughout.

I would highly recommend Delta to anyone.

New to Kitchener area and my first experience with Delta Air. Cannot say enough about the entire team that helped me out. Huge compliments go out to Megan the technician, Tanya who provided the quote, and of course huge thank you to Liam B and Fabio. This team provided professional service along with great helpful information in a very friendly and timely manner. Liam and Fabio did an amazing job with the install and took great care of my home as they wielded large furnace pieces through my small home. I would highly recommend Delta Air Systems to anyone for sure. Thank you everyone for making this such a great experience.

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.

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!
