What size furnace do I need?

January 31, 2019

When it’s time to upgrade your outdated furnace, it’s important to understand one size does not fit all. A system that is not sized appropriately for your home, will not only hurt your comfort, but can lead to shortened life of your furnace, and leave you stuck with higher energy bills.

If you choose a unit oversized for your house, you’ll start to notice short cycles. This means your oversized furnace heated your home too fast, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to shortened lifespan and cost you more in energy bills.

How can you be certain about the proper furnace size for your home? Begin with a load calculation from the team at Walter's-Eaton's Electric, Plumbing, Heating & AC. A load calculation takes aspects from your home into account and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—How big 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 accounted for during this process. Many times, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping your home through the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the experts from Walter's-Eaton's Electric, Plumbing, Heating & AC review the insulation in your walls and attic. They’ll help you select the 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Factor in the range of weather you receive in Ellsworth. You’ll want a furnace that can keep up with the conditions of your climate every year, without overworking itself.
