What size furnace do I need?

January 31, 2019

When it’s time to upgrade your outdated furnace, it’s important to understand one size does not fit all.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 mean a shortened life of your furnace, and leave you with larger energy costs.

If you choose a unit oversized for your home, you’ll start to experience 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 reduced lifespan and higher costs.

How can you be confident in the right furnace size for your home? Start with a load calculation from the team at American HVAC Inc. A load calculation takes particulars from your home into review and gauges the Btu (a number that indicates the heating capacity of a furnace) needed to heat your home.

Some Items that Influence Furnace Size

  • Square Footage—How large is the area your furnace will have to heat up? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be included 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 you’ll need. Let the team from American HVAC Inc take a look at the insulation in your walls and attic. They’ll help you find a best furnace for your house.
  • Type of Window— Just like your walls, the certain 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—Consider the range of weather you experience in Sacramento. You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
