Furnace Size Calculator

Answer these seven brief questions to find out what size of furnace your house needs.

Furnace size is measured by how many BTUs it uses per hour to achieve a certain temperature increase. BTU (an abbreviation for British Thermal Unit) is a unit of measurement for energy; it’s the industry standard measurement for the heating efficiency of furnaces.

BTUs are used as an estimate for the amount of energy the equipment will use to heat a space. Because home heating and cooling demands vary greatly, furnaces are available with BTU ratings ranging from 40,000 to over 200,000 BTU. Most furnaces range between 80,000 and 100,000 BTU.
