HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When the time comes to replace your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized correctly for your home, will not only affect your comfort, but can lead to shortened life of your furnace, and leave you spending extra money on your utility bills.

If you pick a unit oversized for your house, you’ll start to run into short cycles. This means your oversized furnace heated your home too quickly, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to reduced lifespan and bigger expenses.

How can you be sure you know the right furnace size for your home? Start with a load calculation from the team at Stieferman Heating Company Inc. A load calculation takes specifics from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) required to heat your home.

Some Factors that Influence Furnace Size

  • Square Footage—What size is the area your furnace will need to heat? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be accounted for during this process. Usually, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from filtering out of your home throughout the cold winter months. It also heavily affects energy efficiency and how large of a heating system will be necessary. Let the team from Stieferman Heating Company Inc take a look at the insulation in your walls and attic. They’ll help you select the perfect furnace for your house.
  • Type of Window— Just like your walls, the specific type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Think about the range of weather you experience in Jefferson City. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
