A1 Air Conditioning & Heating

During a particularly cold evening, our heating system unexpectedly stopped working, creating an urgent need for assistance. The A1 team responded swiftly and efficiently, demonstrating their commitment to customer satisfaction from the very beginning. Scott, the sales representative, provided thorough guidance on available options and explained the benefits of incorporating a fan-powered humidifier into our installation. Bradley, the technician assigned to the project, handled the equipment setup with exceptional skill and professionalism. His meticulous approach ensured that every aspect of the installation met the highest standards, offering us peace of mind and comfort during the process. Based on this outstanding experience, I confidently and strongly endorse the expertise and reliability of the A1 team for any HVAC needs.

I have just had my 23 year old furnace, that shut off last evening during this cold snap, repaired by a lovely gentleman, Bruce at A1 heating. I had to go one night without heat as I needed a part they had to order. But Bruce was here today and got my furnace started again! They were not sure the part would work, but Bruce did a thorough job and stayed until he knew the furnace was working. The company was very pleasant to work with. I definitely need a new furnace soon and I will be happy to work with this company again. In the meantime, our family is happy to heat on for this cold snap. Thanks A1 and Bruce

Highly recommend A1! My husband and I needed a new AC and furnace system, so we gathered three quotes and spoke with three different sales consultants. Frank Sanelli from A1 immediately stood out because of his hands on technical and implementation experience. He clearly understood the system requirements and ensured that what he recommended was truly the best fit for our home. He also proposed an alternative electric solution, something the other companies did not consider, which turned out to be both highly efficient for our setup and the most cost effective option. The A1 installation team was professional and friendly, completing the installation same day. They left everything in great shape with minimal clean up afterward. Overall, we are extremely happy with the entire experience!

I live in Downtown Toronto & In Sept. & October of 2025 got a GENIUS HEAT PUMP for my Ductless A/C with 3 Headers from KRYSTIN KOWAL from A1Air Conditioning & Heating. I was SO IMPRESSED & HAPPY with my new GENIUS Heat Pump & with Krystin (Sales consultant ) & the 2 Installers : JUSTIN & OLLIVER that I ALSO purchased a Package Deal for a NEW NAVIEN NFB—175 BOILER from KRYSTIN at A1 Air Conditioning & Heating in Oakville. which was Installed by Rob & Keil who went beyond the call of duty to answer ALL MY QUESTIONS & do a Superb & timely job. Justin & Olliver The High Installers who went up to my 3 rd floor to install the Ductless A/C when other Companies refused. Krystin & ALL THE INSTALLERS were SO PROFESSIONAL & had a great deal of pride of workmanship in what they did that I would highly recommend them to anyone who needs new Air Conditioning especially Ductless & a BOILER. Their prices were very competitive & I saved money by purchasing the A/C in the Fall & by doing the Boiler at the same time. I had quotes from 2 other reputable Companies but chose A1 from Oakville because of their maintenance plans , expertise ,Customer Service , follow up & All the guys at A1 & Krystin, of course, who turned what was a terrible experience into a great one for me ! Thanks SO MUCH to ALL of you ! It was a pleasure doing business with you!
