A leak in the air conditioning unit isn’t a problem that should be ignored. Even the smallest leaks can cause electrical issues or mold and mildew growth. If you spot water dripping from the AC unit, a professional HVAC technician can determine the cause and fix the problem. Below are some of the most common culprits of AC leaks.

Why Is Your AC Unit Leaking?

1. Clogged Drain Line

The condensate drain line siphons moisture away from the air conditioning system. If the line becomes clogged by algae, dirt, and other debris, it will prevent water from exiting properly and cause moisture to drip from the unit.

2. Broken Drain Pan

Your AC unit has a drain pan welded to its underside to collect condensation. If this pan breaks, corrodes, or sustains other damage, it will cause water to leak out of the unit. This situation is common in systems that are over 12 years old and will typically require a replacement.

3. Dirty Air Filter

When an AC filter becomes blocked by dirt and dust, it can restrict airflow over the evaporator coil and cause the component to freeze. Eventually, the ice will melt and overflow in the drain pan. To avoid this scenario, replace the unit’s filter every two to three months.

4. Low Refrigerant

Refrigerant, which is sometimes referred to as coolant, creates the cool air inside the AC unit. When the liquid leaks, the system can’t cool the hot interior air, which causes the frozen evaporator coil to heat up and release condensation into the drain pan. If the compartment is too full, it spill liquid into your house.
