HVAC Contractor helping a couple choose a furnace

What size furnace do I need?

When the time comes to upgrade your outdated furnace, it’s important to realize one size does not fit all. A system that is not sized properly for your home, will not only hurt your comfort, but can result in shortened life of your furnace, and leave you stuck with higher energy bills.

If you select a furnace oversized for your space, you’ll start to experience short cycles. This means your oversized furnace heated your home too fast, turning off before the furnace can reach correct 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? Get started with a load calculation from the team at Jent Mechanical LLC. A load calculation takes specifics from your home into account and gauges the Btu (a number that indicates the heating capacity of a furnace) needed to heat your house.

Some Factors that Influence Furnace Size

  • Square Footage—How big 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 needs to be considered during this process. Often, 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 is required. Let the team from Jent Mechanical LLC take a look at the insulation in your walls and attic. They’ll help you choose the 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 play into what heating and cooling needs your home requires.
  • Outdoor Climate—Factor in the range of weather you receive in Dayton. You’ll want a furnace that can handle the conditions of your environment every year, without overworking itself.
