HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When the time comes to update your outdated furnace, it’s important to realize one size does not fit all.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 properly for your home, will not only affect your comfort, but can result in shortened life of your furnace, and leave you stuck with higher energy bills.

If you pick a system oversized for your home, you’ll start to notice short cycles. The reason is that your oversized furnace heated your home too fast, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to decreased lifespan and bigger expenses.

How can you be sure you know the proper furnace size for your home? Start with a load calculation from the team at Wallpe Heating & Cooling. A load calculation takes specifics from your home into consideration and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your house.

Some Items that Influence Furnace Size

  • Square Footage—How big is the area your furnace will need to heat? Your 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 valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping your home during the cold winter months. It also strongly affects energy efficiency and how large of a heating system you’ll need. Let the team from Wallpe Heating & Cooling review 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Consider the range of weather you experience in Greensburg. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
