Choosing the Right Size Air Conditioning Unit

Tonnage And BTUs

In order to determine which size is right for your home, it’s best to start with an understanding of how it all works. The sizing of an AC unit is measured in tonnage, which is not the weight of the unit, but it’s ability to cool a space. With a one-ton air conditioner, it is capable of cooling 12,000 BTU (British Thermal Unit) in an hour. A BTU is how we measure the energy that’s required to cool one pound of water by one degree. If you get an air conditioner that is one ton, it can cool 12,000 pounds of water by one degree in an hour. As the BTU increases, the stronger it is and it will use more energy.

Air Conditioning Service FredericksburgWhy Size Matters

You may be thinking that the larger the air conditioning unit is, the better. You do want a cool house all of the time, right? Well, it doesn’t really work that way. And if you want to run your AC unit efficiently and protect your wallet as well, it’s important to pay attention to size.

If It’s Too Big

A large AC unit will cool the house very quickly, which may sound like a good thing, but there is a consequence. When the house is cooled quickly, the AC unit will turn off quickly too. This quick on and off process doesn’t let the system run through the entire cycle that it is supposed to, allowing warm air to seep into your home, requiring the system to turn back on again. This is incredibly inefficient and will cause your electric bill to rise.

If It’s Too Small

As you can probably guess, when the unit is too small it will constantly be running to try to cool your home. If the unit is multiple sizes too small, it will have a hard time keeping your home as cool as you’d like it. This will again cause your electric bill to rise.

When considering the right size AC unit for your home, ask yourself these questions:

  • How hot does it get in the Fredericksburg area?
  • Is there shade around your house?
  • Is there a basement or a slab?
  • What color is your roof?
  • What is the square footage of your home?
  • How tall are the ceilings?

A 2.5-ton unit should be enough to efficiently cool a space that is between 1,300 and 1,600 square feet. But it’s best to get a professional opinion on the correct size air conditioner for your home.
