Sizing Your Air Conditioner

This is what you need to know when it comes to sizing your air conditioner. Make sure that you keep these guidelines in mind when you need quality service:

  • Oversized and Undersized Systems: If you’re looking into how to perfectly size an air conditioning system, you should familiarize yourself with the terms “oversized” and “undersized.” We want you to know that these terms don’t literally refer to the physical size of the air conditioning system—it refers to power and capacity of your AC system.
  • Load Calculations: A load calculation is what our professionals will perform to make sure that you get the perfect air conditioner for your home. When we conduct this calculation, we consider the size of your home, the amount of people living in your home, the layout of your home, and the materials used to construct your home.
  • Tonnage: Tonnage refers to the amount of heat that your air conditioner can remove from your home within an hour. This is measured in BTUs.

The Problem With an Improperly Sized AC

Now, let’s get into improperly sized air conditioners. We’ll go through units that are either too big or too small.

Too Big

Having an air conditioner that’s too big is proof that bigger isn’t always better. You need an air conditioning system that’s perfectly fitted to your home. You don’t want an air conditioner that’s too big because it’s going to flood your home with cool air too fast. Then you’ll run into problems like short cycling.

Short cycling is when your air conditioner starts, runs for a limited amount of time, stops short, and then starts the entire process again in short succession. This happens because your air conditioner is too large for your space.

You don’t want to let this go on forever because short cycling is so hard on your home’s air conditioner. The start-up portion of an air conditioning cycle is the hardest part of the cooling process. If your air conditioner is forced to do this multiple times an hour due to short cycling, your air conditioner is much more likely to give out on you sooner.  

Too Small

When you have an air conditioner that is too small, you’ll notice that you’re lack in the comfort category. You’re not going to get cool if your air conditioner can’t perform for your space.
