What size furnace do I need?

January 31, 2019

When the time comes to update your outdated furnace, it’s important to realize one size does not fit all.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 stuck with higher energy bills.

If you choose a unit oversized for your space, you’ll start to notice 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 decreased lifespan and bigger expenses.

How can you be sure you know the correct furnace size for your home? Begin with a load calculation from the team at Jack's Heating, Cooling, Stoves & Fireplaces. A load calculation takes aspects from your home into review and measures the Btu (a number that indicates the heating capacity of a furnace) needed to heat your home.

Some Things that Influence Furnace Size

  • Square Footage—How large is the area your furnace will have to heat up? A 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. Usually, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping your home throughout the cold winter months. It also strongly affects energy efficiency and how large of a heating system is required. Let the professionals from Jack's Heating, Cooling, Stoves & Fireplaces 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Think about the range of weather you experience in Alliance. You’ll want a furnace that can keep up with the conditions of your climate every year, without overworking itself.
