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When it’s time to replace your outdated furnace, it’s important to realize one size does not fit all.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 lead to shortened life of your furnace, and leave you with larger energy costs.

If you select a furnace oversized for your space, you’ll start to notice short cycles. This means 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 reduced lifespan and bigger expenses.

How can you be sure you know the right furnace size for your home? Get started with a load calculation from the professionals at KDM Service Corporation. A load calculation takes aspects from your home into account and measures the Btu (a number that indicates the heating capacity of a furnace) required to heat your home.

Some Factors that Influence Furnace Size

  • Square Footage—How big is the area your furnace will need to heat? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home needs to be considered during this process. Many times, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from filtering out of 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 KDM Service Corporation take a look at the insulation in your walls and attic. They’ll help you select 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Think about the range of weather you experience in Tuscaloosa. You’ll want a furnace that can sustain the conditions of your climate every year, without overworking itself.
