HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to replace your outdated furnace, it’s important to know that one size does not fit all.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 appropriately for your home, will not only hurt your comfort, but can lead to shortened life of your furnace, and leave you spending extra money on your utility bills.

If you select a unit oversized for your space, you’ll start to run into short cycles. This means 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 certain about the correct furnace size for your home? Begin with a load calculation from the team at Giordanos Heating and Air Conditioning. 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 space.

Some Items that Influence Furnace Size

  • Square Footage—What size is the area your furnace will have to heat up? A technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be considered during this process. Often, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from leaving your home throughout the cold winter months. It also strongly affects energy efficiency and how large of a heating system will be necessary. Let the team from Giordanos Heating and Air Conditioning 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 get in Derby. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
