How to Tell if Your A/C is Oversized

We sometimes get asked, “Why do you schedule in-home estimates instead of just selling the equipment?” Reputable HVAC companies take this extra step instead of just selling you equipment for an important reason: in-home estimates let us know what size A/C you need!

Two homes can buy the same model of A/C, but the size of the unit will vary depending on the unique factors of each home. If you purchase a unit that is incorrectly sized, you can face issues with your HVAC system, which is why it’s extremely important to have your equipment sized for your home.

Here are the top three problems that can occur as the result of an improperly-sized A/C unit:

Short Cycling:

Air conditioners run until the indoor temperature reaches the desired setting on your thermostat. If your A/C is oversized, it will pump out cold air at a quicker rate, rapidly lowering the temperature. This may sound like a good thing, but it cuts the A/C cycle short and prevents your home from being cooled properly.

If your A/C runs for less than ten minutes at a time, you might have an oversized unit.


Your air conditioner’s secondary function, in addition to cooling your home, is to remove humidity from the air. If your unit is short cycling because it is too big, it won’t have enough time to properly lower the humidity levels in your home.


The wear and tear of your unit constantly starting and stopping can shorten the life expectancy of your A/C (and raise your monthly bills!).
