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When it’s time to upgrade your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized properly for your home, will not only affect your comfort, but can mean a shortened life of your furnace, and leave you spending extra money on your utility bills.

If you choose a furnace oversized for your space, you’ll start to run into short cycles. This is because your oversized furnace heated your home too quickly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to shortened lifespan and cost you more in energy bills.

How can you be sure you know the right furnace size for your home? Get started with a load calculation from the team at Turner Brothers Heating & Air Conditioning. A load calculation takes particulars from your home into account and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your home.

Some Things that Influence Furnace Size

  • Square Footage—How large 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 may be accounted for during this process. Many times, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from escaping your home through the cold winter months. It also heavily affects energy efficiency and how large of a heating system is required. Let the team from Turner Brothers 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—Consider the range of weather you experience in Saint Marys. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
