Where We've Been

History & Heritage

From its start in Toronto in 1956, G & M Heating Supplies Ltd. has been a family-owned wholesale distribution company serving southern Ontario HVAC contractors.

In May 1996, G & M Heating Supplies Ltd. acquired Air Heat Supplies from the Olsen Furnace Company. With the original Toronto location kept as a branch, a new 40,000 sq. ft. Mississauga head office was opened under the name Air Heat Supplies, A Division of G & M Heating Supplies Ltd.

A third Scarborough location was opened in 2004. Air Heat became the exclusive Ontario distributor of award-winning American Standard Heating and Air Conditioning systems and equipment in 2005. Since then, they have established a network of 170 independent American Standard dealers across Ontario.

A Distribution Center was opened in Ottawa in the summer of 2008. Two years later, a 2,000 sq. ft. Home Comfort Training Center was opened near the Head Office in Mississauga. Offering a regular calendar of free technical, sales, and third party vendor training courses, this cutting edge facility also provides hands-on training using fully operational HVAC, IAQ and Hydronic systems.  In December 2011, a distribution center was opened in London to better serve south-western Ontario contractors.

Now a second-generation family-owned and operated business, Air Heat has a growing customer base of over 1,500 contractors and employs about 75 people in their Head Office, branches,  distribution centers, and Home Comfort Training Center.

Air Heat has always provided a one-stop contractor experience with one of the largest high quality HVAC/IAQ parts and supplies catalogues in Ontario. In addition to the full line of American Standard residential and light commercial HVAC products, Air Heat now sources products from over 70 leading suppliers, including Honeywell, Alltemp, Canadian General Filters, Aprilaire, & White-Rodgers.
