What size furnace do I need?

January 31, 2019

When it’s time to update your outdated furnace, it’s important to realize one size does not fit all.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 impact your comfort, but can result in shortened life of your furnace, and leave you with larger energy costs.

If you select a furnace oversized for your space, you’ll start to experience short cycles. This is because your oversized furnace heated your home too rapidly, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to reduced lifespan and cost you more in energy bills.

How can you be confident in the proper furnace size for your home? Begin with a load calculation from the professionals at Farris Heating & Air. A load calculation takes particulars from your home into consideration and measures the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—What size is the area your furnace will be heating? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home needs to be considered during this process. Often, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from leaving your home during the cold winter months. It also strongly affects energy efficiency and how large of a heating system you’ll need. Let the team from Farris Heating & Air review the insulation in your walls and attic. They’ll help you find a ideal furnace for your house.
  • Type of Window— Just like your walls, the particular type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will play into what heating and cooling needs your home requires.
  • Outdoor Climate—Consider the range of weather you experience in Bartlesville. You’ll want a furnace that can sustain the conditions of your area every year, without overworking itself.
