How big of a furnace or air conditioner do I need for my home?

The only way to size a furnace or air conditioner for your home is to do a heat load calculation. The capacity needed is based upon how quickly your home gains or loses heat, not by square footage alone. ACCA's Manual J is an industry-approved method that Coolray uses to insure the proper system is selected for you.
