What size furnace do I need?

January 31, 2019

When you need to replace your outdated furnace, it’s important to realize one size does not fit all.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

If you choose a system oversized for your house, you’ll start to notice 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 bigger expenses.

How can you be certain about the right furnace size for your home? Get started with a load calculation from the experts at Lanz Furnace and Fireplace. A load calculation takes aspects from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your home.

Some Things that Influence Furnace Size

  • Square Footage—How large 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 valuable to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from filtering out of 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 Lanz Furnace and Fireplace take a look at the insulation in your walls and attic. They’ll help you choose the 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Factor in the range of weather you get in Monroe. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
