What size furnace do I need?

January 31, 2019

When it’s time to upgrade your outdated furnace, it’s important to understand one size does not fit all. A system that is not sized correctly for your home, will not only impact your comfort, but can lead to shortened life of your furnace, and leave you spending extra money on your utility bills.

If you choose a system 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 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 sure you know the proper furnace size for your home? Get started with a load calculation from the team at Southern Heating & Cooling Inc.. A load calculation takes particulars from your home into review and measures the Btu (a number that indicates the heating capacity of a furnace) needed to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—How big is the area your furnace will be heating? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be considered during this process. Often, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping 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 team from Southern Heating & Cooling Inc. evaluate 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 Scottsboro. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.
