What size furnace do I need?

January 31, 2019

When it’s time to update your outdated furnace, it’s important to realize one size does not fit all.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 impact your comfort, but can lead to shortened life of your furnace, and leave you with larger energy costs.

If you select a unit oversized for your home, you’ll start to notice short cycles. This means your oversized furnace heated your home too quickly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to decreased lifespan and bigger expenses.

How can you be sure you know the proper furnace size for your home? Begin with a load calculation from the team at Connolly Electric & Mechanical. A load calculation takes aspects from your home into account and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

Some Factors 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 may be accounted for during this process. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from leaving your home through the cold winter months. It also greatly affects energy efficiency and how large of a heating system will be necessary. Let the experts from Connolly Electric & Mechanical take a look at the insulation in your walls and attic. They’ll help you choose the 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Think about the range of weather you get in Cottonwood . You’ll want a furnace that can handle the conditions of your climate every year, without overworking itself.
