Furnaces and central air conditioning combinations consist of three (3) major components: an outdoor condenser and indoors, a furnace and coil. The indoor components can be located in many places including the basement, an attic, a closet, or on the main floor depending upon the design of your home. Many different styles of units are available to accommodate your needs. Ask your local Independent Armstrong Air dealer what equipment is best for your home or business. You can use the Find Your Dealer link on this site.
