Performed as stipulated, on time at agreed price. Pleasant, reasonably tidy. Helped with advice on operation of an earlier installation. Will definitely recommend and use them again. Thanks to Denise and crew.

We had no heat and we called a few different companies. We decided to go with Air Treatment because they were professional, quick to respond, and reasonably priced. A service technician came to our house and explained the options once we realized the furnace was broken. We decided to replace the furnace and Air Treatment had an install team there the next morning. They were clean, quiet, and explained how all the equipment worked. We would definitely recommend them to our friends! Thanks again

Timely done, as per quote.

Took care of removing old A/C from the attic. covered all surfaces to eliminate dust. Very professional!!

Highly recommended.

This company is servicing my heating/AC units for the past 13 years. Honest & always on time! Their emergency service is amazing as well!

The work was completed professiobalky and with care. I found the cost to be reasonable and everything was explained to me clearly, I understood what I was paying for and will continue to use Air Treatment in the future.

I had Air Treatment Install a new furnace and air conditioner, the level of service was amazing all the way from sales team to the install crew. They helped determine the right unit for my home. The Installers were well-informed, polite and tidy. I would recommend Air Treatment to all my friends!

Air Treatment installed a Fujitsu ductless A/C system for us way back in 2009. Online reviews were much less common then, but the installation and the reliability over the past 9 years has been excellent, prompting me to finally write a review. I just contacted Air Treatment because we need to have two more end-of-life A/C systems replaced in our rambling old Toronto home, and my first choice remains Air Treatment to do the job. Denise is still on the job and has been with the company for a long time, always a good sign.

Based on that excellent experience 9 years ago, in 2018 Denise McCormack quoted us for a Fujitsu Ductless Heat Pump, a Payne furnace, and a Payne central air conditioner. It was a huge job in a rambling century home that called for lots of creativity and skill. Scott Bennett (Sr HVAC Engineer) and Derek Gray (HVAC Tech) were brilliant and met every challenge. The workmanship was superb and exceeded expectations. Scott's standards are very high, and he will never take a shortcut or let anything defeat him. The attention to detail and cleanliness were superb. Why couldn't every contractor have the standards of Air Treatment?

A really pleasant experience and the best part, they provided a furnace for much less than the gas provider. The gas provider was quoting on a furnace that was more than our small house required. Installers were polite and knew their business. They cleaned up well after themselves.

Denise from Air Treatment is fabulous! She visited us in June as our Air Conditioner needed to be replaced. She took a look at what we had & showed us several new models that would suit our needs. She went over pricing & gave us the best unit for the best price.

As soon as I called to inquire about possible dates for the installation Air Treatment were able to offer me the exact date & time I asked for.
The two fellows arrived on time, were respectful & installed the new Air conditioner in the exact amount of time we had been quoted. They left the workspace neat & tidy & the airconditioner running as it was another hot day! We couldn't be happier! Thank you Denise & Air Treatment!

Air Treatment installed a new system at my house. They did an incredible job and were extremely professional. They made sure to explain everything they were doing and also left no mess at all.

Thanks again
