What size furnace do I need?

January 31, 2019

When it’s time to replace your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized correctly for your home, will not only affect 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 house, you’ll start to notice short cycles. This is because your oversized furnace heated your home too rapidly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to shortened lifespan and higher costs.

How can you be certain about the correct furnace size for your home? Start with a load calculation from the experts at Kowalski Heating, Cooling & Plumbing. A load calculation takes aspects from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) required to heat your house.

Some Factors 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 included 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 escaping your home throughout the cold winter months. It also strongly affects energy efficiency and how large of a heating system you’ll need. Let the team from Kowalski Heating, Cooling & Plumbing review the insulation in your walls and attic. They’ll help you select the perfect furnace for your house.
  • Type of Window— Just like your walls, the specific 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 McMurray. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
