What size furnace do I need?

January 31, 2019

When the time comes to update your outdated furnace, it’s important to realize one size does not fit all.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 lead to shortened life of your furnace, and leave you with larger energy costs.

If you choose a unit oversized for your home, 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 proper operating temperatures. An undersized or oversized system can lead to reduced lifespan and higher costs.

How can you be confident in the right furnace size for your home? Get started with a load calculation from the experts at Smyth Air Conditioning Inc. A load calculation takes particulars from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) required to heat your house.

Some Items that Influence Furnace Size

  • Square Footage—How big 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 will be accounted for during this process. Often, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from filtering out of your home during the cold winter months. It also heavily affects energy efficiency and how large of a heating system will be necessary. Let the professionals from Smyth Air Conditioning Inc review the insulation in your walls and attic. They’ll help you select 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Think about the range of weather you receive in Lake Worth. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
