What size furnace do I need?

January 31, 2019

When the time comes to replace your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized correctly 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 select a furnace oversized for your house, you’ll start to run into 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 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 professionals at Dave's Diversified Services. A load calculation takes particulars 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 Things that Influence Furnace Size

  • Square Footage—How big is the area your furnace will have to heat up? Your 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 during the cold winter months. It also strongly affects energy efficiency and how large of a heating system will be necessary. Let the professionals from Dave's Diversified Services review 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 influence your heating and cooling requirements.
  • Outdoor Climate—Consider the range of weather you experience in Front Royal. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.
