HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to replace your outdated furnace, it’s important to know that one size does not fit all.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 with larger energy costs.

If you choose a unit oversized for your home, you’ll start to notice short cycles. This means your oversized furnace heated your home too rapidly, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to reduced lifespan and bigger expenses.

How can you be sure you know the right furnace size for your home? Begin with a load calculation from the team at Total Comfort. A load calculation takes specifics from your home into account and identifies the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your house.

Some Factors that Influence Furnace Size

  • Square Footage—How large is the area your furnace will have to heat up? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be accounted for during this process. Usually, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from escaping your home through the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the professionals from Total Comfort evaluate the insulation in your walls and attic. They’ll help you select 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 influence your heating and cooling requirements.
  • Outdoor Climate—Factor in the range of weather you experience in Franklin Lakes. You’ll want a furnace that can keep up with the conditions of your climate every year, without overworking itself.
