How To Select The Right Size AC Unit For Your Home?

Many people choose air conditioners that are too small or too large for their homes, causing all sorts of problems. In addition, an oversized air conditioner can cause just as much trouble as a small one. It’s not an uncommon problem. To assist you with this issue, contact a professional for AC installation in Hollywood, FL, who can help you determine the perfect sized unit for your setting.

What are the benefits of Installing the Correct Size of Air Conditioners ?

  • If your air conditioner is too small, it will need to run longer to cool your home, resulting in higher energy bills. On the other hand, if your air conditioner is too large, it will cycle on and off frequently, increasing your energy bill.
  • A poorly sized air conditioner cannot maintain a consistent temperature in your home. Some rooms in your home may be too hot and others too cold.
  • If your air conditioner cycles on and off too frequently, it may make strange sounds, such as banging or clicking. It is a sign that your home is too small for the unit.
  • Air conditioners that are too small will have to work harder to cool your home, and they will wear out sooner. On the other hand, a large air conditioner will cycle on and off too frequently, which can also cause damage.

How to Calculate Your Cooling Unit's Size?

Three basic elements need to be understood to calculate the appropriate size.

You can solve this problem by multiplying the length by the width of the area that needs cooling. Once that amount is calculated, multiply it by 25 BTU.

Suppose your room measures 13 feet by 16 feet, for example. In other words, it will cover 208 square feet (13 x 16). The amount of 208 square feet should be multiplied by 25 BTU per square foot again. It is recommended that you need 5200 BTUs of cooling capacity in total.

It is most appropriate to use this measurement to calculate a single room’s size. The calculator estimates the amount of cooling your system will need. To calculate the size of the central air conditioner, you need to consider the size of the house. A recommendation from an expert is better in this case.


By calling a house estimate service, you can reduce your burden of choosing the perfect air conditioning system because they will consider all factors. Whether installing or replacing your air conditioner, Air Conditioning ProTech Corp will ensure the right size is selected for your home.
