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When it’s time to upgrade your outdated furnace, it’s important to know that one size does not fit all. A system that is not sized correctly for your home, will not only affect your comfort, but can lead to shortened life of your furnace, and leave you stuck with higher energy bills.

If you pick a unit oversized for your home, you’ll start to notice short cycles. This is because 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 higher costs.

How can you be sure you know the right furnace size for your home? Begin with a load calculation from the experts at Morgner Inc. Air Conditioning & Heating. 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 Things that Influence Furnace Size

  • Square Footage—What size is the area your furnace will be heating? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home will be included during this process. Usually, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from filtering out of your home throughout the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the professionals from Morgner Inc. Air Conditioning & Heating take a look at the insulation in your walls and attic. They’ll help you find a ideal furnace for your house.
  • Type of Window— Just like your walls, the particular 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—Factor in the range of weather you experience in St. Louis. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
