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When the time comes to update your outdated furnace, it’s important to know that one size does not fit all.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 correctly for your home, will not only affect your comfort, but can result in shortened life of your furnace, and leave you stuck with higher energy bills.

If you pick a unit oversized for your home, you’ll start to experience 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 decreased lifespan and bigger expenses.

How can you be confident in the proper furnace size for your home? Start with a load calculation from the team at Stieferman Heating Company Inc. A load calculation takes aspects from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) required to heat your house.

Some Items that Influence Furnace Size

  • Square Footage—How large is the area your furnace will be heating? 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. Usually, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from filtering out of your home throughout the cold winter months. It also greatly affects energy efficiency and how large of a heating system will be necessary. Let the experts from Stieferman Heating Company Inc review 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 influence your heating and cooling requirements.
  • Outdoor Climate—Think about the range of weather you experience in Jefferson City. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
