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.

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.
