The most honest HVAC company in the GTA!

Jack came over, was able to offer a reasonable solution to my home temperature issues.
When on site, realized that half of the job was not necessary. Let me know and didn’t charge me for needless work.

After the adjustment, I had overpaid - MAS refunded the difference on their own initiative.
David H Toronto
I recently installed heating, air conditioning, a water heater, and a water softener, all thanks to the recommendations from sales representative Shawn.

He was extremely professional and provided fair pricing tailored to my house.

Shawn promptly addressed any questions I had before and after installation.
Miranda Z North York
My furnace stopped working in a Sat morning, then I start looking for solutions.

My friend refered Norman to me and he came to check for me 2 hours later found out that the heat exchanger was gone.

Very fast response and great service, thumbs up! Will definitely recommend Norman to my friends
Jackie C Richmond Hill
We want to replace our water tank to an energy saving tankless water heater and sought assistance from this company. Shawn, our advisor, was exceptionally patient and thorough. He took the time to explain all possible options and detail with us, ensuring he fully understood our needs and preferences as customers. When it came time for the installation, David, the technician, was incredibly professional. He arrived promptly, worked efficiently, and maintained a high level of cleanliness throughout the process. His attention to detail and meticulous approach ensured everything was installed perfectly. I have nothing but good things to say. 
Cherry P Scarborough
Very happy with their service. Our furnace broke down on the weekend, and they booked to come the next day for a replacement.
The rep (Shawn) on the phone was very knowledgeable. His quote was a good price and it came with labour cost all inclusive, so no hidden fees.
When they got here, the technicians are highly skilled, hard working, and took the time to explain and answer our many questions. I am recommending these guys to my friends.

Yes. We offer free on-site assessments and quotes for furnace installation, repair and maintenance. Our technicians review your heating system, explain the recommended work and provide a quote before you decide. The assessment is free; any approved service work is quoted separately.

It depends on your furnace’s age, condition and repair costs. A minor problem may only need a repair, while frequent breakdowns or major component issues may make replacement worth considering. Our team can assess your system and explain your options.

Most residential furnaces benefit from professional maintenance once a year, ideally before the heating season. Regular service can help identify developing problems, check safe operation and keep your heating system running reliably.

A cold-climate heat pump may be an option, depending on your home and heating needs. Some systems work alongside an existing furnace. Mas Air can help you explore available heating options before you make a decision.
