What size furnace do I need?

January 31, 2019

When you need to replace your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized appropriately 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 select a unit oversized for your home, 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 correct 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? Begin with a load calculation from the experts at McFadden Heating & Cooling. A load calculation takes aspects from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) needed to heat your house.

Some Factors that Influence Furnace Size

  • Square Footage—How large is the area your furnace will be heating? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be accounted for during this process. Often, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from leaving your home through the cold winter months. It also strongly affects energy efficiency and how large of a heating system is required. Let the experts from McFadden Heating & Cooling review 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 influence your heating and cooling requirements.
  • Outdoor Climate—Factor in the range of weather you receive in Dresden. You’ll want a furnace that can sustain the conditions of your area every year, without overworking itself.
