What size furnace do I need?

January 31, 2019

When you need to replace your outdated furnace, it’s important to know that one size does not fit all.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 stuck with higher energy bills.

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

How can you be certain about the right furnace size for your home? Get started with a load calculation from the professionals at Total Comfort. A load calculation takes specifics from your home into consideration and measures the Btu (a number that indicates the heating capacity of a furnace) needed to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—How large 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 may be considered during this process. Usually, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from filtering out of your home throughout the cold winter months. It also heavily affects energy efficiency and how large of a heating system you’ll need. Let the team from Total Comfort 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Think about the range of weather you experience in Franklin Lakes. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
