HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When you need to replace your outdated furnace, it’s important to understand one size does not fit all.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 stuck with higher energy bills.

If you choose a unit oversized for your home, you’ll start to notice short cycles. This means your oversized furnace heated your home too rapidly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to reduced lifespan and higher costs.

How can you be sure you know the right furnace size for your home? Start with a load calculation from the team at Rapids Sheet Metal Works Inc. A load calculation takes aspects 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 Items that Influence Furnace Size

  • Square Footage—How big 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 will be considered during this process. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation works to 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 find a best 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 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.
