What size furnace do I need?

January 31, 2019

When it’s time to replace your outdated furnace, it’s important to know that one size does not fit all.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 result in shortened life of your furnace, and leave you spending extra money on your utility bills.

If you choose a system oversized for your space, you’ll start to notice 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 higher costs.

How can you be confident in the correct furnace size for your home? Begin with a load calculation from the professionals at Honke Heating & AC. A load calculation takes particulars from your home into consideration 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 have to heat up? Your 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 valuable to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from filtering out of your home through the cold winter months. It also strongly affects energy efficiency and how large of a heating system you’ll need. Let the professionals from Honke Heating & AC review the insulation in your walls and attic. They’ll help you find a 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 get in Gresham. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
