HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When it’s time to upgrade your outdated furnace, it’s important to know that one size does not fit all.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

If you choose a system oversized for your space, you’ll start to run into short cycles. The reason is that 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 certain about the proper furnace size for your home? Start with a load calculation from the professionals at Rescue Heating & Air . A load calculation takes particulars from your home into account and measures 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 big is the area your furnace will have to heat up? 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. 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 greatly affects energy efficiency and how large of a heating system will be necessary. Let the team from Rescue Heating & 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 Alice. You’ll want a furnace that can keep up with the conditions of your environment every year, without overworking itself.
