HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to replace your outdated furnace, it’s important to understand one size does not fit all. A system that is not sized correctly 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 system oversized for your house, you’ll start to notice short cycles. The reason is that your oversized furnace heated your home too rapidly, turning off before the furnace can reach proper 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 team at Rapids Sheet Metal Works Inc. A load calculation takes specifics from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—How big 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 accounted for during this process. Many times, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from escaping your home through the cold winter months. It also heavily affects energy efficiency and how large of a heating system will be necessary. Let the experts from Rapids Sheet Metal Works Inc 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Factor in the range of weather you get in Wisconsin Rapids. You’ll want a furnace that can sustain the conditions of your area every year, without overworking itself.
