The size of a heating furnace plays a huge role in its performance. For a furnace to deliver the right amount of warmth to your living space, it needs to be the correct size for your home. Wastage of energy, high heating costs, and over-heating of the home are often associated with over-sized furnace. On the other hand, an under-sized furnace will not be able to heat up your home properly during the cold winter months. To enjoy maximum indoor comfort during the winter, you need to install the correct size of furnace in your home.

Several factors come into play when determining the size of furnace for your home. The square footage, the furnace efficiency, the climate of the area, and the quality and amount of insulation in a home—all of these factors must be carefully examined in order to arrive at the correct size of heating furnace for your home.

A standard that commonly used by HVAC companies is to provide a minimum of 25-30 British thermal units (BTU) per square feet to homes located in areas with moderate or warm climate, such as San Carlos, CA. Using this standard, a mid-sized home of 20,000 square feet will require about 50,000 to 60,000 Btu to heat it up properly during the cold winter months. A 60,000 to 72,000-Btu furnace with an efficiency rating of 80% will satisfactorily meet the heating needs of a 20,000 square feet home.
