What size furnace do I need?

Installation

When the time comes to update your outdated furnace, it’s important to realize one size does not fit all.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 impact your comfort, but can lead to shortened life of your furnace, and leave you spending extra money on your utility bills.

If you select a system oversized for your space, you’ll start to experience short cycles. This is because 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 right furnace size for your home? Begin with a load calculation from the experts at Central Air Inc. A load calculation takes specifics from your home into review and measures the Btu (a number that indicates the heating capacity of a furnace) required to heat your home.

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 valuable to account only for the space that needs heating.
  • Home Insulation—Insulation assists in keeping warm air from leaving 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 Central 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 influence your heating and cooling requirements.
  • Outdoor Climate—Consider the range of weather you receive in Clackamas. You’ll want a furnace that can sustain the conditions of your climate every year, without overworking itself.
