HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to upgrade your outdated furnace, it’s important to understand one size does not fit all.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 select a furnace oversized for your house, you’ll start to run into short cycles. The reason is that 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 reduced lifespan and bigger expenses.

How can you be sure you know the proper furnace size for your home? Start with a load calculation from the team at Kirkfield Heating & Air Conditioning. A load calculation takes aspects 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 Factors that Influence Furnace Size

  • Square Footage—How large is the area your furnace will need to heat? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home needs to be included during this process. Usually, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from filtering out of your home through the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the professionals from Kirkfield Heating & Air Conditioning evaluate 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—Think about the range of weather you get in Winnipeg. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
