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When the time comes to replace your outdated furnace, it’s important to understand one size does not fit all.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 properly 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 pick a furnace oversized for your home, you’ll start to experience short cycles. The reason is that your oversized furnace heated your home too quickly, turning off before the furnace can reach correct operating temperatures. An undersized or oversized system can lead to shortened lifespan and cost you more in energy bills.

How can you be sure you know the correct furnace size for your home? Begin with a load calculation from the experts at A2Z Air 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 home.

Some Factors that Influence Furnace Size

  • Square Footage—What size is the area your furnace will need to heat? Your technician will be sure to carefully measure the square footage of your home. Not every inch of your home needs to be considered during this process. Usually, it is more useful to account only for the space that needs heating.
  • Home Insulation—Insulation helps keep warm air from escaping your home during the cold winter months. It also greatly affects energy efficiency and how large of a heating system will be necessary. Let the professionals from A2Z Air Inc review the insulation in your walls and attic. They’ll help you find a perfect furnace for your house.
  • Type of Window— Just like your walls, the specific 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 receive in Boynton Beach. You’ll want a furnace that can sustain the conditions of your environment every year, without overworking itself.
