If I Replace My Furnace, What Size Will I Need?

Published on: October 16, 2013

If you’re looking to replace your furnace, you no doubt have many questions. What type of furnace? What brand? In addition to those questions, when it comes time to replace a furnace, what size is also a common and very important question.

It’s important that you have the right size furnace for several reasons. A furnace that’s too small won’t heat your home adequately, while one that’s too large will not only cost more to run, but it will also need repair and replacement more frequently. This is because it will put out too much heat in a short period of time, and as a result, will shut itself off and on more often than it should. This is called short cycling, and it adds significantly more wear and tear on your furnace.

When determining the right furnace size for your home, don’t look to the current size, as it may not be accurate. An HVAC professional can assess your needs. Here are some of the things that will factor in to determining the right size furnace for your home:

  • Square footage of your home
  • Insulation and other energy efficiency factors
  • Layout of the home
  • Number of people living in the home
  • Landscape elements, such as shade trees and direction of sunlight, among others
