What size furnace do I need?

January 31, 2019

When you need to update your outdated furnace, it’s important to realize one size does not fit all.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 affect your comfort, but can lead to shortened life of your furnace, and leave you stuck with higher energy bills.

If you choose a furnace oversized for your house, 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 correct operating temperatures. An undersized or oversized system can lead to decreased lifespan and cost you more in energy bills.

How can you be confident in the correct furnace size for your home? Get started with a load calculation from the professionals at Gee & Missler Heating & Air Conditioning. A load calculation takes specifics from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) required to heat your space.

Some Things that Influence Furnace Size

  • Square Footage—How big is the area your furnace will be heating? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home needs to be accounted for during this process. Often, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from escaping your home during the cold winter months. It also strongly affects energy efficiency and how large of a heating system will be necessary. Let the experts from Gee & Missler Heating & Air Conditioning evaluate the insulation in your walls and attic. They’ll help you choose 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 influence your heating and cooling requirements.
  • Outdoor Climate—Factor in the range of weather you get in Wyandotte. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
