What size furnace do I need?

January 31, 2019

When the time comes to update your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized appropriately for your home, will not only hurt your comfort, but can mean a shortened life of your furnace, and leave you spending extra money on your utility bills.

If you pick a system oversized for your house, you’ll start to experience 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 cost you more in energy bills.

How can you be certain about the correct furnace size for your home? Get started with a load calculation from the team at Winters Heating and Cooling. A load calculation takes specifics from your home into consideration and measures the Btu (a number that indicates the heating capacity of a furnace) required to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—How large is the area your furnace will have to heat up? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be considered during this process. Usually, it is more valuable 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 is required. Let the professionals from Winters Heating and Cooling take a look at 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 influence your heating and cooling requirements.
  • Outdoor Climate—Think about the range of weather you get in Franklin. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
