What size furnace do I need?

When it’s time to replace your outdated furnace, it’s important to know that one size does not fit all.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

If you pick a unit oversized for your home, you’ll start to run into short cycles. The reason is that your oversized furnace heated your home too rapidly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to reduced lifespan and higher costs.

How can you be certain about the correct furnace size for your home? Get started with a load calculation from the team at Guidry's Air Conditioning & Refrigeration Service. A load calculation takes specifics from your home into consideration and measures the Btu (a number that indicates the heating capacity of a furnace) necessary 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 may be included during this process. Often, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from escaping your home throughout the cold winter months. It also heavily affects energy efficiency and how large of a heating system you’ll need. Let the team from Guidry's Air Conditioning & Refrigeration Service evaluate 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 influence your heating and cooling requirements.
  • Outdoor Climate—Consider the range of weather you experience in Raceland. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
