What size furnace do I need?

January 31, 2019

When it’s time to replace your outdated furnace, it’s important to realize one size does not fit all.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

If you pick a system 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 shortened lifespan and higher costs.

How can you be sure you know the correct furnace size for your home? Start with a load calculation from the team at Assured Appliance and Heating & Air. A load calculation takes specifics from your home into account and gauges the Btu (a number that indicates the heating capacity of a furnace) needed to heat your space.

Some Things that Influence Furnace Size

  • Square Footage—How large is the area your furnace will have to heat up? Your 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 valuable to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from leaving 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 Assured Appliance and Heating & Air take a look at 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—Think about the range of weather you get in Genoa. You’ll want a furnace that can keep up with the conditions of your area every year, without overworking itself.
