What size furnace do I need?

January 31, 2019

When it’s time to replace your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized correctly 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 system oversized for your home, you’ll start to notice short cycles. This is because your oversized furnace heated your home too quickly, turning off before the furnace can reach the right operating temperatures. An undersized or oversized system can lead to reduced lifespan and bigger expenses.

How can you be certain about the correct furnace size for your home? Begin with a load calculation from the experts at JTech Mechanical. A load calculation takes specifics from your home into account and gauges the Btu (a number that indicates the heating capacity of a furnace) required to heat your home.

Some Things that Influence Furnace Size

  • Square Footage—How large is the area your furnace will have to heat up? A 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 useful to account only for the space that needs heating.
  • Home Insulation—Insulation works to keep warm air from filtering out of your home during the cold winter months. It also greatly affects energy efficiency and how large of a heating system is required. Let the experts from JTech Mechanical evaluate the insulation in your walls and attic. They’ll help you find a ideal furnace for your house.
  • Type of Window— Just like your walls, the particular 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 receive in Magnolia. You’ll want a furnace that can handle the conditions of your area every year, without overworking itself.
