What size furnace do I need?

January 31, 2019

When the time comes to replace your outdated furnace, it’s important to realize one size does not fit all.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 impact your comfort, but can mean a shortened life of your furnace, and leave you stuck with higher energy bills.

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

How can you be certain about the correct furnace size for your home? Begin with a load calculation from the professionals at Air Temperature Control. A load calculation takes aspects from your home into consideration and measures 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 big 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 will be accounted for during this process. Often, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from leaving your home through the cold winter months. It also strongly affects energy efficiency and how large of a heating system will be necessary. Let the professionals from Air Temperature Control evaluate 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Consider the range of weather you get in Macon. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
