HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When the time comes to update your outdated furnace, it’s important to understand one size does not fit all.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

If you choose a furnace oversized for your space, you’ll start to notice short cycles. The reason is that your oversized furnace heated your home too rapidly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to decreased lifespan and bigger expenses.

How can you be certain about the right furnace size for your home? Get started with a load calculation from the experts at Local HVAC Repair & Service . A load calculation takes particulars from your home into account and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your home.

Some Factors that Influence Furnace Size

  • Square Footage—How big 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 assists in keeping warm air from filtering out of your home throughout the cold winter months. It also heavily affects energy efficiency and how large of a heating system you’ll need. Let the team from Local HVAC Repair & Service 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 Wheeling. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
