What size furnace do I need?

January 31, 2019

When it’s time to update your outdated furnace, it’s important to know that one size does not fit all.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 stuck with higher energy bills.

If you select a unit oversized for your space, you’ll start to notice short cycles. This is because your oversized furnace heated your home too rapidly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to decreased lifespan and bigger expenses.

How can you be sure you know the proper furnace size for your home? Get started with a load calculation from the team at Siloam Springs Heating & AC. A load calculation takes specifics from your home into review and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

Some Items that Influence Furnace Size

  • Square Footage—How big is the area your furnace will be heating? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be considered during this process. Many times, 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 through the cold winter months. It also strongly affects energy efficiency and how large of a heating system will be necessary. Let the experts from Siloam Springs Heating & AC evaluate the insulation in your walls and attic. They’ll help you select the 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Consider the range of weather you get in Siloam Springs. You’ll want a furnace that can sustain the conditions of your area every year, without overworking itself.
