What size furnace do I need?

January 31, 2019

When it’s time to replace your outdated furnace, it’s important to understand one size does not fit all.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 lead to shortened life of your furnace, and leave you stuck with higher energy bills.

If you choose a system oversized for your home, you’ll start to run into short cycles. This is because your oversized furnace heated your home too quickly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to reduced lifespan and cost you more in energy bills.

How can you be sure you know the correct furnace size for your home? Get started with a load calculation from the experts at Freed Heating & Air Conditioning. A load calculation takes specifics from your home into account and measures the Btu (a number that indicates the heating capacity of a furnace) required to heat your house.

Some Items 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 considered 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 during the cold winter months. It also greatly affects energy efficiency and how large of a heating system you’ll need. Let the experts from Freed Heating & Air Conditioning evaluate 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 influence your heating and cooling requirements.
  • Outdoor Climate—Consider the range of weather you get in Moline. You’ll want a furnace that can sustain the conditions of your climate every year, without overworking itself.
