When you need to update your outdated furnace, it’s important to realize one size does not fit all.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 with larger energy costs.

If you pick a system oversized for your home, you’ll start to run into short cycles. The reason is that 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 a reduced life span and cost you more in energy bills.

How can you be certain about the proper furnace size for your home? Get started with a load calculation from the team at Watts Electric & AC. A load calculation takes specifics from your home into account and identifies the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

Some Things that Influence Furnace Size

  • Square Footage—What size 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 may be included during this process. Usually, 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 will be necessary. Let the professionals from Watts Electric & AC 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 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 experience in Columbia. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
