HVAC Contractor helping a couple choose a furnace

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When the time comes to replace your outdated furnace, it’s important to realize one size does not fit all.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 correctly for your home, will not only impact 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 house, you’ll start to run into short cycles. The reason is that your oversized furnace heated your home too fast, 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 confident in the correct furnace size for your home? Get started with a load calculation from the experts at Bain Heating & Air Conditioning, Inc. A load calculation takes specifics from your home into account 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 needs to be accounted for 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 escaping your home through the cold winter months. It also greatly affects energy efficiency and how large of a heating system you’ll need. Let the professionals from Bain Heating & Air Conditioning, Inc take a look at 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 have an impact on the heating and cooling needs of your home.
  • Outdoor Climate—Factor in the range of weather you receive in Heflin. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.

Don’t settle for ‘close enough’ when choosing your new furnace. Let the professionals at Bain Heating & Air Conditioning, Inc help you find a system that will fit your home properly.
