HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When you need to replace your outdated furnace, it’s important to realize one size does not fit all.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 affect your comfort, but can result in shortened life of your furnace, and leave you spending extra money on your utility bills.

If you choose a system oversized for your home, you’ll start to experience short cycles. This means your oversized furnace heated your home too fast, turning off before the furnace can reach proper 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 correct furnace size for your home? Begin with a load calculation from the team at AW Heating & Air Conditioning. A load calculation takes aspects from your home into review and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your space.

Some Items that Influence Furnace Size

  • Square Footage—How large 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 accounted for during this process. Usually, it is more useful 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 is required. Let the professionals from AW Heating & Air Conditioning evaluate the insulation in your walls and attic. They’ll help you select the 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 Lincoln. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
