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When it’s time to update your outdated furnace, it’s important to understand one size does not fit all.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

If you choose a system oversized for your home, you’ll start to run into short cycles. This means your oversized furnace heated your home too fast, turning off before the furnace can reach proper operating temperatures. An undersized or oversized system can lead to shortened lifespan and higher costs.

How can you be confident in the right furnace size for your home? Begin with a load calculation from the team at All Weather Heating & Air Conditioning Inc. A load calculation takes aspects from your home into review and gauges the Btu (a number that indicates the heating capacity of a furnace) necessary to heat your house.

Some Things that Influence Furnace Size

  • Square Footage—How big is the area your furnace will be heating? 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 works to keep warm air from leaving your home throughout the cold winter months. It also strongly affects energy efficiency and how large of a heating system will be necessary. Let the experts from All Weather Heating & Air Conditioning Inc 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 influence your heating and cooling requirements.
  • Outdoor Climate—Factor in the range of weather you experience in Huntsville. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
