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When it’s time to upgrade your outdated furnace, it’s important to realize one size does not fit all.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 lead to shortened life of your furnace, and leave you with larger energy costs.

If you select a system oversized for your space, you’ll start to notice short cycles. This is because 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 decreased lifespan and bigger expenses.

How can you be certain about the right furnace size for your home? Start with a load calculation from the team at Gillman Heating and Air. A load calculation takes aspects from your home into consideration and measures the Btu (a number that indicates the heating capacity of a furnace) required to heat your space.

Some Items that Influence Furnace Size

  • Square Footage—How big 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 will 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 escaping your home throughout the cold winter months. It also strongly affects energy efficiency and how large of a heating system will be necessary. Let the team from Gillman Heating and Air take a look at the insulation in your walls and attic. They’ll help you find a ideal furnace for your house.
  • Type of Window— Just like your walls, the particular type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will influence your heating and cooling requirements.
  • Outdoor Climate—Think about the range of weather you get in Perry. You’ll want a furnace that can keep up with the conditions of your area every year, without overworking itself.
