What size furnace do I need?

January 31, 2019

When it’s time to upgrade your outdated furnace, it’s important to understand one size does not fit all.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

If you select a unit oversized for your house, you’ll start to run into short cycles. This is because your oversized furnace heated your home too rapidly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to shortened lifespan and bigger expenses.

How can you be certain about the correct furnace size for your home? Get started with a load calculation from the experts at Morgner Inc. Air Conditioning & Heating. A load calculation takes particulars from your home into account and gauges the Btu (a number that indicates the heating capacity of a furnace) required to heat your space.

Some Factors that Influence Furnace Size

  • Square Footage—How large 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 needs to be accounted for during this process. Often, it is more beneficial 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 is required. Let the team from Morgner Inc. Air Conditioning & Heating evaluate the insulation in your walls and attic. They’ll help you find a 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 St. Louis. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
