What size furnace do I need?

January 31, 2019

When the time comes to upgrade your outdated furnace, it’s important to realize one size does not fit all.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 hurt your comfort, but can lead to shortened life of your furnace, and leave you spending extra money on your utility bills.

If you select a unit oversized for your home, you’ll start to notice short cycles. This is because your oversized furnace heated your home too fast, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to reduced lifespan and cost you more in energy bills.

How can you be confident in the proper furnace size for your home? Start with a load calculation from the team at Hale's Air Conditioning Services Inc. A load calculation takes specifics from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

Some Things that Influence Furnace Size

  • Square Footage—How large is the area your furnace will have to heat up? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be included during this process. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from leaving your home during the cold winter months. It also heavily affects energy efficiency and how large of a heating system is required. Let the team from Hale's Air Conditioning Services Inc take a look at the insulation in your walls and attic. They’ll help you find a 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 receive in Saint Petersburg. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
