HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to update your outdated furnace, it’s important to realize one size does not fit all.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

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 rapidly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to shortened lifespan and higher costs.

How can you be sure you know the right furnace size for your home? Begin with a load calculation from the professionals at Wolfe & Sons Heating and Cooling. 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—What size 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 included 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 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 Wolfe & Sons Heating and Cooling take a look at 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 influence your heating and cooling requirements.
  • Outdoor Climate—Factor in the range of weather you get in Columbus. You’ll want a furnace that can sustain the conditions of your climate every year, without overworking itself.
