What size furnace do I need?

January 31, 2019

When you need to upgrade your outdated furnace, it’s important to realize one size does not fit all.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 hurt your comfort, but can result in shortened life of your furnace, and leave you with larger energy costs.

If you choose a unit oversized for your home, you’ll start to experience short cycles. This is because 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 reduced lifespan and cost you more in energy bills.

How can you be certain about the right furnace size for your home? Start with a load calculation from the experts at Integrity AC & Heating LLC. A load calculation takes aspects from your home into review and gauges the Btu (a number that indicates the heating capacity of a furnace) needed to heat your home.

Some Items 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 will be accounted for during this process. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from filtering out of 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 experts from Integrity AC & Heating LLC 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Consider the range of weather you get in Phoenix. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
