British thermal unit is a measuring tool of temperature. It is defined as the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit. Why is Btu important? Because the number of Btus needed for your home corresponds to the square footage you’re trying to heat and cool. The larger your home, the more Btus you want. Find out if it’s time for a new furnace or how to cut down on heating costs.
