The size of an air conditioner has a significant impact on its efficiency. When installing a new air conditioner, have skilled AC professionals help you choose the right size for your home. 

If you install an AC that is not suitable for your home, you may face a slew of problems or require emergency AC repair in Dallas in the future.

What Happens if your AC Unit is Incorrectly Sized?

  • When your AC unit is oversized
    Oversized systems attain your ideal temperature faster and cycle on and off more frequently. Conversely, short-cycling reduces the efficiency and life of your system. 
    It needs to work harder to turn on after each shutdown. Furthermore, big units cannot adequately dehumidify a home, which may result in moisture issues.
  • When your AC unit is too small
    If your AC team is too short for the room, it will not be efficient enough. That forces the system to run longer than necessary to maintain temperature, making it difficult to keep enough air cool.
    An undersized AC unit is more prone to failure and may void your manufacturer’s warranty. You may believe that a small system will save you money, but you will pay for it in the long run.

How do you Determine Air Conditioner Size?

To determine the exact capacity of AC, multiply the length by the width of the available area and then multiply that sum by 25 BTU. That is how you may select an air conditioner that provides adequate cooling on hot sunny days. 

The basic room size is 100 square grounds if the room is 10 feet wide and 10 feet long. That means the air conditioner with a cooling capacity of 100*25=2500 BTUs is the best match for your available space.


Making a hasty decision can cost you comfort or costly AC repair in Dallas. If you want to maximize the return on investment from your AC, make sure it is appropriately sized.
