East Peoria, IL, has cold, snowy winters. You’ll need a reliable furnace to keep your home warm and safe. When it’s time to replace your old furnace, you might be wondering what size or capacity of a new one to buy. Our technicians at Accurate Heating & Cooling will make sure you get the proper furnace. Here are the ways we’ll determine the right size of heating system for your home.

Heating Load Calculation

Our technicians will perform a heating load calculation. To do that, we use a formula established by the American Society of Heating, Refrigeration and Air Conditioning Engineers. The calculation considers your home’s size, age, building materials, windows, doors, configuration, geographic location, and more.

Estimate the Size Yourself

The Department of Energy has established climate zones for the United States. If you know your climate zone and your home’s square footage, you can estimate the amount of British Thermal Units (BTUs) your home needs for heat. East Peoria is in climate zone 4, which requires 45 to 50 BTUs per square foot.

Other Factors to Consider When Sizing a Furnace

If your home has 11-foot ceilings, it will need more BTUs than a home with 9-foot ceilings. Homes with inadequate ducts may also need a bigger furnace or improvements made to the ducts. If your home lacks adequate insulation, it’s a good idea to have new insulation installed before buying a furnace. You might find that fixing the insulation and ducts reduces your home’s BTU requirements.
