What size furnace do I need?

January 31, 2019

When the time comes to upgrade your outdated furnace, it’s important to understand one size does not fit all. A system that is not sized properly for your home, will not only affect your comfort, but can result in shortened life of your furnace, and leave you stuck with higher energy bills.

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

How can you be certain about the proper furnace size for your home? Start with a load calculation from the experts at Mayeuxs AC & Heating. A load calculation takes specifics from your home into review and gauges the Btu (a number that indicates the heating capacity of a furnace) required to heat your home.

Some Items 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 will be accounted for during this process. Usually, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from escaping your home through the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the professionals from Mayeuxs AC & Heating evaluate the insulation in your walls and attic. They’ll help you find a 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—Factor in the range of weather you get in Norco and St. Charles Parish. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
