It’s summertime, and you’ve noticed your AC never stops running.
Should you be concerned?
Here’s the thing: It’s normal for your AC to run continuously during hot summer months.
You see, on extremely hot days—we’re talkin’ high 90s to 100s—your system needs to keep up with the incoming heat. To do that, it will run longer in order to maintain a constant, desired temperature in your home.
However, if your AC is always running but you’re never comfortable, that’s a clear sign of a problem that needs to be fixed.
Here are 4 common causes of an AC that constantly runs and never delivers.
Your system requires a certain amount of airflow to cool your home. If airflow is blocked or restricted in any way, your system works harder and runs longer.
Common culprits of this issue include dirty air filters, leaky or disconnected ducts and closed or blocked air vents. So…
If your inside unit’s evaporator coil is dirty it makes it tough for refrigerant (or “Freon”) to absorb heat from your air.
The same goes for dirt buildup on an outside unit’s condenser coils. A dirty condenser can block the release of absorbed heat from the refrigerant.
Basically, both issues will cause your system to run constantly since it’s struggling to remove heat from your home.
When your system is low on refrigerant, it will struggle to reach the temperature setting, causing it to run constantly.
You need a professional to check your system's refrigerant level. If it’s low, make sure they find and fix the leak (since a leak is why you lose refrigerant), and then add more.
An undersized AC is like “The Little Engine That Could” but can't. It will constantly run but the system is simply too small to meet your home’s cooling demands.

Have a professional air conditioning contractor perform a heat load calculation on your home to know what size (measured in tons) your home needs. If you suspect this is your problem you’ll want to fix it fast to prevent costly repairs with your compressor due to frozen coils and constant wear and tear from your system working too hard.
