HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When the time comes to update your outdated furnace, it’s important to understand one size does not fit all.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

If you choose a unit oversized for your space, you’ll start to notice 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 decreased lifespan and bigger expenses.

How can you be confident in the proper furnace size for your home? Get started with a load calculation from the experts at Fleming Heating & Air Conditioning Inc.. A load calculation takes aspects from your home into consideration and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your space.

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 included during this process. Usually, 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 through the cold winter months. It also heavily affects energy efficiency and how large of a heating system is required. Let the experts from Fleming Heating & Air Conditioning Inc. take a look at the insulation in your walls and attic. They’ll help you select the 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—Consider the range of weather you receive in South Beloit and Belvidere. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
