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When you need to replace your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized appropriately for your home, will not only impact your comfort, but can mean a shortened life of your furnace, and leave you stuck with higher energy bills.

If you choose a system oversized for your space, you’ll start to run into short cycles. This means 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 certain about the proper furnace size for your home? Begin with a load calculation from the experts at Kapaun & Brown Inc.. A load calculation takes specifics from your home into account and gauges the Btu (a number that indicates the heating capacity of a furnace) required to heat your house.

Some Things that Influence Furnace Size

  • Square Footage—How large is the area your furnace will have to heat up? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be accounted for during this process. Many times, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from leaving your home through the cold winter months. It also strongly affects energy efficiency and how large of a heating system you’ll need. Let the team from Kapaun & Brown Inc. evaluate the insulation in your walls and attic. They’ll help you choose 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Consider the range of weather you receive in Marshalltown. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
