If you’re considering a system replacement, fall is a good time to do so. But before you rush out and get an upgraded version of what you have now—or a bigger system—be careful to consider the air conditioner’s size. If sizing is ignored, you may very well find yourself replacing your entire cooling system way before you should have to.

Why Does My AC Need to Be the Right Size?

Let’s imagine that your cooling system is too small for your living space. If this is the case, then you won’t be able to achieve the right temperature, however your AC will run from long periods of time as it tries to get to that temperature anyway. This will cause your compressor to continuously overheat, which can lead to premature system failure.

But what if it’s too big? Well, then your air conditioner won’t be able to cycle long enough in order to remove humidity from the air. This will result in your unit shutting on and off rapidly—a process called short-cycling—which is inefficient and may eventually cause compressor damage.

So, How Will Professionals Size My AC?

There are a number of considerations that our HVAC professionals make when determining the right size cooling system for your home. These are some of the factors that they look at:

  • Type of Home Construction
  • Type of Insulation
  • Placement of Windows and Doors
  • Type of Windows
  • Number of People in the Living Space
  • Shading Outside of the Home
