What size furnace do I need?

When the time comes to replace your outdated furnace, it’s important to realize one size does not fit all.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 properly for your home, will not only hurt your comfort, but can result in shortened life of your furnace, and leave you with larger energy costs.

If you select a furnace oversized for your house, you’ll start to notice short cycles. The reason is that your oversized furnace heated your home too quickly, 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 certain about the correct furnace size for your home? Get started with a load calculation from the team at Davis Heating & Air Conditioning. A load calculation takes specifics from your home into review and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your house.

Some Things that Influence Furnace Size

  • Square Footage—How large 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 needs to be included 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 strongly affects energy efficiency and how large of a heating system you’ll need. Let the experts from Davis Heating & Air Conditioning take a look at the insulation in your walls and attic. They’ll help you find a perfect furnace for your house.
  • Type of Window— Just like your walls, the specific 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 get in Rocky Mount. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
