Quick Answer:
If your AC is leaking water, turn off the system, check for a clogged drain line or dirty air filter and call a licensed HVAC technician to inspect and repair the issue. Common causes include:
- A clogged condensate drain line
- Frozen evaporator coils
- A cracked or overflowing drain pan
Is It Dangerous If My AC Is Leaking?
While a water leak isn’t usually dangerous, it can cause water damage or mold growth if ignored — and refrigerant leaks should always be handled by professionals.
A water leak from your AC is usually caused by condensation buildup and isn’t harmful by itself. However, if you notice oily residue, a chemical smell or hissing noises, you could be dealing with a refrigerant (Freon) leak, which is hazardous and requires immediate professional help.
If you’re unsure, it’s safest to call an HVAC expert like Express Air Conditioning and Heating to inspect your system.
Common Reasons Your AC Is Leaking Water
1. Clogged Condensate Drain Line
The drain line removes humidity pulled from your home’s air. Dirt and debris can clog it, causing water to back up and leak around your unit. This is one of the most common (and easily preventable) issues homeowners face.
2. Frozen Evaporator Coils
When airflow is restricted — usually due to a dirty air filter — the coils can freeze over. As the ice melts, it creates excess water that may overflow the pan. Regular filter changes and AC tune-ups help prevent this.
3. Damaged Or Overflowing Drain Pan
The drain pan sits beneath the evaporator coils to collect condensation. If it’s cracked, rusted or full, water will leak instead of draining properly. A technician can quickly replace or repair the pan.
What To Do When You See A Leak
Follow these simple steps to minimize damage until a professional arrives:
- Turn off your AC at the thermostat and breaker.
- Replace your air filter if it’s dirty.
- Empty the drain pan if you can access it.
- Check for obvious blockages in the drain line.
