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When you need to replace your outdated furnace, it’s important to know that one size does not fit all.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 properly for your home, will not only hurt your comfort, but can lead to shortened life of your furnace, and leave you with larger energy costs.

If you pick a furnace oversized for your home, you’ll start to run into short cycles. The reason is that your oversized furnace heated your home too rapidly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to reduced lifespan and higher costs.

How can you be sure you know the proper furnace size for your home? Start with a load calculation from the professionals at Air Commander's Heating & Air Conditioning Co.. A load calculation takes aspects from your home into consideration and measures the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your house.

Some Items that Influence Furnace Size

  • Square Footage—How big 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 will be accounted for during this process. Usually, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from leaving your home during the cold winter months. It also heavily affects energy efficiency and how large of a heating system will be necessary. Let the experts from Air Commander's Heating & Air Conditioning Co. 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Think about the range of weather you receive in Haines City. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
