When you need to replace your outdated furnace, it’s important to know that one size does not fit all.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 spending extra money on your utility bills.

If you choose a system oversized for your home, you’ll start to notice short cycles. This is because 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 a decreased life span and bigger expenses.

How can you be certain about the proper furnace size for your home? Get started with a load calculation from the professionals at B & G HVAC. A load calculation takes specifics 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 Factors 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 will be included during this process. Many times, it is more beneficial 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 professionals from B & G HVAC review 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 specific type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will play into what heating and cooling needs your home requires.
  • Outdoor Climate—Think about the range of weather you experience in Marshalltown. You’ll want a furnace that can sustain the conditions of your area every year, without overworking itself.
