HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to upgrade your outdated furnace, it’s important to realize one size does not fit all.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

If you pick a unit oversized for your home, you’ll start to run into short cycles. This means your oversized furnace heated your home too quickly, turning off before the furnace can reach correct 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? Get started with a load calculation from the team at McFadden Heating & Cooling. A load calculation takes specifics from your home into review and measures the Btu (a number that indicates the heating capacity of a furnace) required to heat your home.

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 needs to be accounted for during this process. Many times, 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 during the cold winter months. It also heavily affects energy efficiency and how large of a heating system you’ll need. Let the team from McFadden Heating & Cooling take a look at the insulation in your walls and attic. They’ll help you choose 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Consider the range of weather you get in Dresden. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.
