A common mistake that homeowners make when purchasing an air conditioner is choosing a system with improper capacity and incorrect sizing for their homes. An error like this can cost you big bucks and cause lasting headaches in the process. Here's a quick look at some of the effects that you may face when dealing with an AC system that is too large or too small for your home.


Air Conditioner Too Large

If your system is too large, you run the risk of short cycling. Short cycling is an issue that involves your air conditioner cycling on-and-off very frequently. As a result, your living space is unable to be cooled because the compressor isn’t running long enough to dehumidify your space. Not only that, but the frequent on-and-off cycling means increased energy bills. And to top it all off, your system is more prone to breakdowns due to the added stress of the constant cycling.

Potential Problems 

  • Short cycling
  • Improper cooling
  • Difficulty dehumidifying
  • Increased energy bills
  • Increased stress on system
  • System more prone to breakdowns


Air Conditioner Undersized

If your AC system is undersized, you may experience some of the same problems mentioned above, including an overworked system, and issues with keeping your home cool. You may also have dry and warm air, because of the temperatures not being lowered enough.

Potential Problems 

  • Compressor failure
  • Short cycling
  • Elevated humidity
  • Increased runtime
  • Increased operational costs
  • Shortened equipment life


Purchasing an air conditioner for your home is an investment, and there are many factors to consider when properly sizing HVAC equipment for your home. It is vitally important to pay strict attention when it comes to the sizing of your air conditioner, because the correct size optimizes the performance and life span of your system.
