What size furnace do I need?

January 31, 2019

When you need to update your outdated furnace, it’s important to realize one size does not fit all.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 mean a shortened life of your furnace, and leave you with larger energy costs.

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

How can you be certain about the proper furnace size for your home? Start with a load calculation from the professionals at Breathe Healthier Air. A load calculation takes particulars from your home into account and measures the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your house.

Some Things that Influence Furnace Size

  • Square Footage—How large 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 included during this process. Often, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from filtering out of your home during the cold winter months. It also heavily affects energy efficiency and how large of a heating system is required. Let the professionals from Breathe Healthier Air evaluate the insulation in your walls and attic. They’ll help you find a 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 receive in Stuart. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
