HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to update your outdated furnace, it’s important to realize one size does not fit all.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

If you pick a furnace oversized for your house, you’ll start to experience short cycles. This means your oversized furnace heated your home too quickly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to decreased lifespan and higher costs.

How can you be sure you know the proper furnace size for your home? Start with a load calculation from the team at Scott Temperature. A load calculation takes particulars from your home into account and gauges the Btu (a number that indicates the heating capacity of a furnace) needed 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 may be accounted for during this process. Usually, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from filtering out of your home during the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the team from Scott Temperature take a look at the insulation in your walls and attic. They’ll help you choose the ideal furnace for your house.
  • Type of Window— Just like your walls, the particular type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will influence your heating and cooling requirements.
  • Outdoor Climate—Consider the range of weather you experience in Lawrence. You’ll want a furnace that can keep up with the conditions of your climate every year, without overworking itself.
