Get directionsIntegrity The values and ethics of a company are measured when things go wrong --- not just when they go right. From this perspective A1 are outstanding. I have been a client for 25 years (3 complete HVAC systems purchased + installed) and this past year upgraded the humidifiers to 2 Aprilaire 800 steam units at a total cost of $3,700. Their performance was a real let-down --- no real improvement in humidification. A1 sent techs Robert and Theo who determined that the water conditions in downtown Toronto were not conducive t... read more

Air Conditioner Daikin Although I feel I may have paid a premium for the product, I am satisfied with the service and installation. The removal and installation of the AC Daikin was quick and neat with the 2 service people being friendly and competent. A kob well done!

Air Conditioning and Furnance purchases & maintenance We have been clients since the mid 1970s and have always found A-1 Air to be reliable, honest and very professional in their service and sales. They have been maintaining our air conditioner and furnace for years and when we needed to replace the furnace 7 years ago we called them. Recently we needed to replace our air conditioner and did not hesitate to call them. Robert helped us with our options and Mike did a great job of installing and quickly followed up with the ex... read more

Broken furnace, service/replace Returned from vacation to find furnace not working, pipes frozen. Called another company who kept promising to come and didn't. Called A1 they came in 2 hours, diagnosed the problem and we had a new furnace up and running by the end of the day. Excellent service, would never call another company.
Business response:
We are thrilled that you had such an excellent experience with us after what I am sure was a very stressful time. Call us anytime! Thank you for sharing!
Furnace and air conditioning The service was excellent, from the salesman who came to my house, the installers, and the girls in the office. Everyone gave good advice and the products are excellent. I have dealt with this company for over 17 years, and I would not use anyone else. They are honest, do not push you into buying anything you don't want and clean up before they leave. They let you know if there are any rebates. Thanks for a great job. 71723

Daikin Furnace & AC Replaced 20 year system with the Daikin (very quiet and efficient). Jeff Smith was professional, informative and responsive. Even though A1 was slightly higher than the competition I felt they were honest and straightforward and worth the small premium. This experience carried through with scheduling and with the installers. They were efficient and respectful of our home, leaving the place clean after the job was complete. Follow up quality inspection happened as committed and a minor issue was fixed righ... read more

Service As always, A 1 Air Conditioning & Heating came to rescue immediately. The staff and service are always kind, knowledgeable and thorough. I had a problem with my air-conditioner. Not only did the service person solve this but also checked through my furnaces and other air-conditioner.
