What size furnace do I need?

January 31, 2019

When the time comes to upgrade your outdated furnace, it’s important to know that one size does not fit all.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 hurt your comfort, but can lead to shortened life of your furnace, and leave you stuck with higher energy bills.

If you pick a unit oversized for your space, you’ll start to notice short cycles. The reason is that your oversized furnace heated your home too quickly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to shortened lifespan and cost you more in energy bills.

How can you be certain about the right furnace size for your home? Start with a load calculation from the professionals at Thurston Heating & Air Conditioning. A load calculation takes particulars from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) needed to heat your home.

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 valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping 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 professionals from Thurston Heating & Air Conditioning 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 influence your heating and cooling requirements.
  • Outdoor Climate—Think about the range of weather you receive in Kearney. You’ll want a furnace that can keep up with the conditions of your area every year, without overworking itself.
