While it’s normal for your air conditioning system to drip condensation while it’s running—especially on hot, humid days—constant puddles of water or indoor leaks are a cause for concern. There are a few different air conditioner repair and maintenance issues that could contribute to this. Here’s a look at the most common.

Why Do AC Units Leak?

1. Blocked Condensate Line

The condensate drain line is the usual culprit behind AC leaks. This line is responsible for getting condensation away from the unit and the house, ensuring that it drips outside. Over time, it can get blocked by mold or sludge that builds up in the moist environment. To fix the clog, the line should be cleaned with a wet/dry vacuum.

2. Refrigerant Leaks

A refrigerant leak lessens your system’s cooling capability. It also lowers the system pressure, which may cause the evaporator coil to freeze.

Exposure to heat will eventually cause this ice to melt, and the drain pan will likely overflow. While air conditioner repair can often repair the refrigerant leak, sometimes the entire unit may need to be replaced.

3. Damaged Drain Pan

The drain pan is designed to collect condensation and get water to the condensate drain line. Over time, however, rust and corrosion can break down the drain pan, allowing water to leak inside the house. This issue is most common in older air conditioning systems, but it’s easily fixed by replacing the damaged drain pan.
