HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to update your outdated furnace, it’s important to know that one size does not fit all.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 impact your comfort, but can result in shortened life of your furnace, and leave you stuck with higher energy bills.

If you choose a furnace oversized for your house, you’ll start to experience short cycles. The reason is that your oversized furnace heated your home too fast, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to shortened lifespan and bigger expenses.

How can you be certain about the right furnace size for your home? Begin with a load calculation from the professionals at WM J Kraus & Son. A load calculation takes specifics from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) needed to heat your home.

Some Things 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 needs to be included during this process. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping 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 experts from WM J Kraus & Son evaluate the insulation in your walls and attic. They’ll help you select the ideal furnace for your house.
  • Type of Window— Just like your walls, the particular type of windows in your home, frame type, glaze type, gas fills/spaces, etc. will have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Consider the range of weather you receive in Keokuk. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.
