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When it’s time to upgrade your outdated furnace, it’s important to understand one size does not fit all. A system that is not sized appropriately for your home, will not only hurt your comfort, but can mean a shortened life of your furnace, and leave you with larger energy costs.

If you select a furnace oversized for your home, you’ll start to run into short cycles. This is because your oversized furnace heated your home too quickly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to decreased lifespan and higher costs.

How can you be certain about the right furnace size for your home? Begin with a load calculation from the team at Schagrin Gas Company. A load calculation takes specifics from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your house.

Some Things that Influence Furnace Size

  • Square Footage—How big is the area your furnace will be heating? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be considered during this process. Usually, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from filtering out of your home through the cold winter months. It also heavily affects energy efficiency and how large of a heating system you’ll need. Let the team from Schagrin Gas Company review the insulation in your walls and attic. They’ll help you choose the 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—Think about the range of weather you get in Middletown. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.
