What size furnace do I need?

When the time comes to replace your outdated furnace, it’s important to understand one size does not fit all. A system that is not sized appropriately for your home, will not only impact your comfort, but can lead to shortened life of your furnace, and leave you with larger energy costs.

If you choose a furnace oversized for your house, you’ll start to experience short cycles. This means 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 cost you more in energy bills.

How can you be certain about the proper furnace size for your home? Get started with a load calculation from the professionals at Dial One Mears Air Conditioning & Heating 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) needed to heat your home.

Some Things that Influence Furnace Size

  • Square Footage—How big is the area your furnace will have to heat up? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home may 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 through the cold winter months. It also strongly affects energy efficiency and how large of a heating system is required. Let the professionals from Dial One Mears Air Conditioning & Heating Inc take a look at 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 experience in Phoenix. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
