What size furnace do I need?

January 31, 2019

When you need to upgrade your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized correctly for your home, will not only hurt your comfort, but can result in shortened life of your furnace, and leave you stuck with higher energy bills.

If you pick a furnace oversized for your house, you’ll start to experience 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 decreased lifespan and higher costs.

How can you be certain about the proper furnace size for your home? Begin with a load calculation from the professionals at Home Comfort Heating & Air. A load calculation takes particulars from your home into account and identifies 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 big is the area your furnace will be heating? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home needs to be accounted for during this process. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from escaping your home during the cold winter months. It also strongly affects energy efficiency and how large of a heating system is required. Let the team from Home Comfort Heating & Air evaluate the insulation in your walls and attic. They’ll help you find a best furnace for your house.
  • Type of Window— Just like your walls, the certain type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will play into what heating and cooling needs your home requires.
  • Outdoor Climate—Factor in the range of weather you receive in Elk River. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
