What size furnace do I need?

January 31, 2019

When you need to update your outdated furnace, it’s important to know that one size does not fit all.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 hurt your comfort, but can lead to shortened life of your furnace, and leave you stuck with higher energy bills.

If you select a furnace oversized for your home, you’ll start to experience short cycles. This is because your oversized furnace heated your home too quickly, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to reduced 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 experts at Three Rivers Heating & Cooling. A load calculation takes particulars from your home into consideration and measures the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your home.

Some Items that Influence Furnace Size

  • Square Footage—How large is the area your furnace will be heating? A 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. Often, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation works to 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 is required. Let the experts from Three Rivers Heating & Cooling 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 receive in Portland. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
