Home improvement and construction supply stores, such as Lowe's and The Home Depot, carry gas furnaces from a number of manufacturers, and any of a wide variety of independently owned dealers. However, many people choose to hire a contractor who installs furnaces to purchase a furnace on their behalf.
When hiring a contractor to choose a gas furnace for a home or business, the consumer should ask for several price estimates. The contractor should determine the proper size of gas furnace for the dwelling, as well as the particular heating needs, before obtaining estimates.
Gas furnace manufacturers, such as Lennox and Trane, provide search fields for dealers by zip code on their websites. AC 4 Life, on the other hand, is a discount supplier of home heating-and-air-conditioning products that sells a wide variety of gas furnaces from a number of manufacturers. Customers using AC 4 Life order online and receive their shipments at home.
When choosing to purchase gas furnaces from an independently owned dealer, it is best to select one that has been in business for a while and has a solidly positive reputation in its respective community. When in doubt, consumers should check the Better Business Bureau or ask the dealer for customer references.
