What size furnace do I need?

January 31, 2019

When the time comes to replace your outdated furnace, it’s important to understand one size does not fit all.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 spending extra money on your utility bills.

If you select a system oversized for your space, you’ll start to notice short cycles. This means your oversized furnace heated your home too rapidly, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to reduced lifespan and cost you more in energy bills.

How can you be certain about the correct furnace size for your home? Get started with a load calculation from the team at AC Sales. A load calculation takes specifics from your home into account and identifies the Btu (a number that indicates the heating capacity of a furnace) needed to heat your home.

Some Items that Influence Furnace Size

  • Square Footage—How large 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 may be considered during this process. Often, it is more valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from escaping your home through the cold winter months. It also greatly affects energy efficiency and how large of a heating system will be necessary. Let the experts from AC Sales take a look at the insulation in your walls and attic. They’ll help you find a best furnace for your house.
  • Type of Window— Just like your walls, the certain 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—Factor in the range of weather you experience in Lafayette. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
