A furnace size calculator is an online tool that helps homeowners determine the appropriate size of furnace for their home. It takes into account factors such as the square footage of the home, the number of rooms, the insulation level, and the climate zone. Furnaces are sized based on British Thermal Units (BTUs), which measure heating output. The calculator will provide a range of BTU outputs that are appropriate for the home, and the homeowner can then choose a furnace that falls within that range.
Using a furnace size calculator is important because it helps to ensure that the furnace is the correct size for the home. A furnace that is too small will not be able to adequately heat the home, while a furnace that is too large will waste energy and money. The calculator can also help homeowners avoid costly mistakes, such as purchasing a furnace that is too large or too small for their needs.
