What size furnace do I need?

January 31, 2019

When it’s time to update your outdated furnace, it’s important to understand one size does not fit all.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 hurt your comfort, but can lead to shortened life of your furnace, and leave you with larger energy costs.

If you choose a system oversized for your home, you’ll start to experience short cycles. This means your oversized furnace heated your home too rapidly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to reduced lifespan and higher costs.

How can you be certain about the correct furnace size for your home? Start with a load calculation from the professionals at Bon Air Service Company. A load calculation takes specifics from your home into account and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your house.

Some Items 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 included during this process. Many times, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from escaping your home during the cold winter months. It also strongly affects energy efficiency and how large of a heating system you’ll need. Let the professionals from Bon Air Service Company review the insulation in your walls and attic. They’ll help you find a best furnace for your house.
  • Type of Window— Just like your walls, the certain 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 Grand Prairie. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
