Why Is My AC Running But Not Cooling?
When the AC runs constantly but the house never cools, the system is working hard with little result. Here is what usually causes it.
Common Causes
- Low refrigerant from a leak
- Frozen evaporator coil from low airflow or low refrigerant
- Dirty outdoor condenser coil that cannot release heat
- Clogged air filter
- Failing compressor or capacitor
What You Can Check Yourself
- Turn the system off for a few hours to let a frozen coil thaw

Why Is My AC Running But Not Cooling?
When your AC runs but does not cool, the likely causes are low refrigerant, a frozen evaporator coil, a dirty outdoor unit, or a dirty filter. Turn the system off to prevent damage, change the filter, clear the outdoor unit, and call a technician if it still will not cool.
Why is my AC frozen with ice on it?
Ice on the coil or lines usually means low airflow or low refrigerant. Turn the AC off, let it thaw, change the filter, and call for service if it freezes again.
Can I add refrigerant myself?
No. Refrigerant requires EPA certification, and a leak that is not fixed will just run out again. A technician should find the leak and recharge it properly.
