What size furnace do I need?

January 31, 2019

When the time comes to update your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized correctly for your home, will not only affect your comfort, but can mean a shortened life of your furnace, and leave you with larger energy costs.

If you select a unit oversized for your home, you’ll start to experience 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 shortened lifespan and bigger expenses.

How can you be sure you know the correct furnace size for your home? Get started with a load calculation from the professionals at Bain Heating & Air Conditioning, Inc. A load calculation takes specifics from your home into consideration and measures the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your house.

Some Factors that Influence Furnace Size

  • Square Footage—How large is the area your furnace will need to heat? 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. Many times, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from escaping your home through the cold winter months. It also heavily affects energy efficiency and how large of a heating system you’ll need. Let the professionals from Bain Heating & Air Conditioning, 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 receive in Heflin. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
