What size furnace do I need?

January 31, 2019

When it’s time to replace your outdated furnace, it’s important to know that one size does not fit all.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 impact your comfort, but can lead to shortened life of your furnace, and leave you stuck with higher energy bills.

If you select a system oversized for your home, you’ll start to run into short cycles. The reason is that your oversized furnace heated your home too quickly, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to shortened lifespan and higher costs.

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—What size 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 accounted for during this process. Usually, 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 through the cold winter months. It also strongly affects energy efficiency and how large of a heating system you’ll need. 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 influence your heating and cooling requirements.
  • 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.
