HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When you need to upgrade your outdated furnace, it’s important to understand one size does not fit all. A system that is not sized properly for your home, will not only impact 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 house, you’ll start to experience short cycles. This means your oversized furnace heated your home too rapidly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to shortened lifespan and cost you more in energy bills.

How can you be sure you know the right furnace size for your home? Begin with a load calculation from the experts at Ken Parker Service Inc. A load calculation takes particulars from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your house.

Some Items that Influence Furnace Size

  • Square Footage—How big 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 may be considered during this process. Many times, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from leaving your home throughout the cold winter months. It also greatly affects energy efficiency and how large of a heating system will be necessary. Let the professionals from Ken Parker Service Inc 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 influence your heating and cooling requirements.
  • Outdoor Climate—Factor in the range of weather you experience in Greenville. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
