HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When the time comes to upgrade your outdated furnace, it’s important to know that one size does not fit all.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

If you pick a unit oversized for your home, you’ll start to run into short cycles. The reason is that 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 shortened lifespan and cost you more in energy bills.

How can you be confident in the correct furnace size for your home? Get started with a load calculation from the team at Air Alliance Team. A load calculation takes particulars from your home into account and measures the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

Some Items that Influence Furnace Size

  • Square Footage—How large is the area your furnace will need to heat? Your 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. Many times, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from leaving your home through the cold winter months. It also greatly affects energy efficiency and how large of a heating system will be necessary. Let the professionals from Air Alliance Team 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Factor in the range of weather you experience in Saint Charles. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
