HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to update your outdated furnace, it’s important to understand one size does not fit all.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

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

How can you be certain about the proper furnace size for your home? Begin with a load calculation from the team at Moon's Air. A load calculation takes aspects from your home into account and measures the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your house.

Some Factors that Influence Furnace Size

  • Square Footage—What size is the area your furnace will need to heat? The technician will be sure to carefully measure the square footage of your home. Not every inch of your home may be accounted for during this process. Often, it is more beneficial to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from filtering out of your home throughout the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the experts from Moon's Air review the insulation in your walls and attic. They’ll help you select the 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Factor in the range of weather you receive in Shreveport. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.
