When it comes to your air conditioning system, you want system that cools your home quickly without having to run non-stop all summer. This may lead you to believe that a bigger AC unit is always better, but did you know that it’s possible to have an AC unit that’s too big for your home?

You Could Have a Poorly Sized Air Conditioning Unit

AC unit size is the measure of an AC unit’s capacity to generate cool air, measured in BTU per hour or tons. Many HVAC specialists oversize air conditioning units, assuming that a home with a certain square footage is going to require a certain size unit. However, this leaves out factors such as how many exterior walls the house has, how much shading surrounds the house, recent energy efficiency upgrades, etc. It’s also possible to have an undersized unit, especially if you’ve recently built a new addition onto your home.

Sizing an AC unit for a house is an intricate process that involves assessing a household’s unique cooling needs and completing a manual J load calculation. If your HVAC contractor did not make these kinds of calculations when installing your air conditioner, chances are it’s improperly sized.
