What size furnace do I need?

January 31, 2019

When it’s time to replace your outdated furnace, it’s important to understand one size does not fit all.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 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 unit oversized for your home, you’ll start to experience short cycles. This means your oversized furnace heated your home too quickly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to decreased lifespan and higher costs.

How can you be confident in the right furnace size for your home? Start with a load calculation from the experts at Ilten's Incorporated. A load calculation takes aspects from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) required to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—How large 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 may be considered during this process. Many times, it is more useful 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 heavily affects energy efficiency and how large of a heating system is required. Let the professionals from Ilten's Incorporated review 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 Cedar Rapids. You’ll want a furnace that can keep up with the conditions of your area every year, without overworking itself.
