What size furnace do I need?

January 31, 2019

When the time comes to upgrade your outdated furnace, it’s important to realize one size does not fit all.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 impact your comfort, but can mean a shortened life of your furnace, and leave you with larger energy costs.

If you choose a unit oversized for your house, you’ll start to notice short cycles. This means 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 shortened lifespan and higher costs.

How can you be confident in the right furnace size for your home? Start with a load calculation from the professionals at Dearing's Service & Solutions. A load calculation takes aspects from your home into account and identifies the Btu (a number that indicates the heating capacity of a furnace) required to heat your home.

Some Factors that Influence Furnace Size

  • Square Footage—What size is the area your furnace will have to heat up? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be included during this process. Usually, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from escaping 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 Dearing's Service & Solutions take a look at the insulation in your walls and attic. They’ll help you choose 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Consider the range of weather you get in Huntingburg. You’ll want a furnace that can keep up with the conditions of your climate every year, without overworking itself.
