Full Answer

British thermal units are the standard measurements used to determine the heating capacity for a furnace. The square footage of a home is used to determine how many BTUs a furnace needs to heat the home. A home located in a cold climate requires more BTUs to heat than a home in a warmer climate. Other issues that factor into the needed furnace size are the amount of insulation in the home, as well as the size and placement of windows.
