What size furnace do I need?

January 31, 2019

When it’s time to upgrade your outdated furnace, it’s important to realize one size does not fit all.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 affect your comfort, but can result in shortened life of your furnace, and leave you with larger energy costs.

If you choose a furnace oversized for your house, you’ll start to run into short cycles. This is because your oversized furnace heated your home too rapidly, 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 confident in the proper furnace size for your home? Get started with a load calculation from the professionals at Franklin's Heating & Air Conditioning, Inc. A load calculation takes aspects from your home into consideration and measures 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—What size is the area your furnace will need to heat? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be included during this process. Often, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from escaping your home throughout the cold winter months. It also heavily affects energy efficiency and how large of a heating system you’ll need. Let the experts from Franklin's Heating & Air Conditioning, Inc 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—Factor in the range of weather you get in Oxford. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
