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When you need to replace your outdated furnace, it’s important to know that one size does not fit all.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 affect your comfort, but can mean a shortened life of your furnace, and leave you spending extra money on your utility bills.

If you select a unit oversized for your home, you’ll start to notice short cycles. The reason is that 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 decreased lifespan and bigger expenses.

How can you be sure you know the correct furnace size for your home? Get started with a load calculation from the experts at Gillman Heating and 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 Items that Influence Furnace Size

  • Square Footage—What size is the area your furnace will need to heat? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be included during this process. Usually, it is more valuable 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 greatly affects energy efficiency and how large of a heating system will be necessary. Let the professionals from Gillman Heating and Air evaluate the insulation in your walls and attic. They’ll help you select the 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 influence your heating and cooling requirements.
  • Outdoor Climate—Factor in the range of weather you get in Perry. You’ll want a furnace that can sustain the conditions of your area every year, without overworking itself.
