Installing a New Air Conditioner: Why Does Size Matter?

Are you considering having a new air conditioning system installed this year? When that time comes, you’ll have many factors to consider. You’ll want to look into system efficiency, its configuration in your house, and even what model is best for you and your home. Another factor you’ll need to consider that is often forgotten is the size of the system.

Many homeowners assume that the bigger the system is, the better it will perform. This is untrue. It’s important that you have one of our professional HVAC technicians help you make an educated decision about the correct size of an air conditioning system. Keep reading to learn more about what happens if your system is too big or too small.

Oversized Air Conditioner

If your air conditioner is oversized, then it’s going to have too much power for your home. This may not seem like a big problem, however this causes your thermostat to shut your AC down before it has a chance to complete a full cycle. This process is called short-cycling and can cause a lot of damage to your air conditioner.

AC systems are designed to put out a certain amount of cool air over a given length of time. When the system short-cycles, the amount of wear and tear on it will be increased. An air conditioner that is too big for its intended space is going to be a lot less efficient than one that is properly sized, and will break down far more often than it otherwise would have.

Undersized Air Conditioner

If your AC system is too small for the space it’s installed in, then it won’t be able to cool your home effectively or efficiently. Too small of a system forces the air conditioner to operate far longer than it is designed to in order to attempt to keep your home cool.

The longer operating times caused by too small of a system makes the cost of using your AC go up. It also contributes to faster wear and tear on the air conditioning system. Unfortunately you’ll find that you need to replace an undersized air conditioner a lot faster than you would have had to otherwise.
