What size furnace do I need?

January 31, 2019

When it’s time to replace your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized properly for your home, will not only hurt your comfort, but can lead to shortened life of your furnace, and leave you with larger energy costs.

If you pick a system oversized for your home, you’ll start to experience short cycles. The reason is that 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 cost you more in energy bills.

How can you be confident in the proper furnace size for your home? Begin with a load calculation from the experts at Kilbourne Heating & AC. A load calculation takes aspects from your home into account 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 big is the area your furnace will be heating? The 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. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping your home through the cold winter months. It also strongly affects energy efficiency and how large of a heating system will be necessary. Let the experts from Kilbourne Heating & AC review the insulation in your walls and attic. They’ll help you find a 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—Think about the range of weather you experience in Delray Beach. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
