When it’s time to update your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized correctly 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 select a furnace oversized for your space, you’ll start to notice short cycles. This means your oversized furnace heated your home too quickly, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to a decreased life span and higher costs.

How can you be sure you know the correct furnace size for your home? Begin with a load calculation from the team at B & G HVAC. A load calculation takes particulars from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) required to heat your space.

Some Things that Influence Furnace Size

  • Square Footage—What size is the area your furnace will be heating? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home needs to be considered during this process. Usually, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping 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 you’ll need. Let the experts from B & G HVAC evaluate 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 certain 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 get in Marshalltown. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
