HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to upgrade your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized appropriately for your home, will not only hurt your comfort, but can lead to shortened life of your furnace, and leave you with larger energy costs.

If you choose a system oversized for your home, you’ll start to run into short cycles. This means your oversized furnace heated your home too fast, turning off before the furnace can reach proper 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 team at Thurston Heating & Air Conditioning. A load calculation takes aspects from your home into consideration and measures the Btu (a number that indicates the heating capacity of a furnace) needed to heat your home.

Some Items that Influence Furnace Size

  • Square Footage—What size is the area your furnace will have to heat up? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be accounted for during this process. Often, 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 is required. Let the team from Thurston Heating & Air Conditioning review the insulation in your walls and attic. They’ll help you choose 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—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.

Don’t settle for ‘close enough’ when choosing your new furnace. Let the qualified technicians at Thurston Heating & Air Conditioning help you pick a system that will fit your home properly.
