If you’re experiencing issues with a leaky AC unit, don’t panic. While it is always frustrating when your AC leaks inside of your home, there are several common reasons it might be doing so, all of which have simple solutions. Here are four common reasons your AC could be leaking and ways to prevent or stop it:

1. A Clogged Drain

If you’re experiencing a leaking AC indoors, this can often be attributed to a clogged drain. Drains can easily get clogged with mold, dirt, debris, or dust. If this is the case, it means water can’t be released through the drain and outside of the home, causing it to leak inside the house. An easy fix to this problem is to unclog the drain with a wet and dry vacuum. If that doesn’t work, it may be time to call in professionals.

2. A Rusty Drain Pan

Condensation pans are part of an AC unit that collects moisture from the inside of your house. This moisture is then drained outside. However, it’s a relatively shallow pan, about an inch deep, and if its drain becomes clogged or rusted, the pan can overflow and leak water into your home. Just like above, try clearing the drain with a wet and dry vacuum or hire the help of a professional.

3. A Dirty Air Filter

Air filters should be changed once a month. If you’re not changing yours out or often forget to do so, this can easily cause your AC unit to leak. Because dirty air filters make an AC system work harder, they are more prone to getting damaged. When a unit’s evaporator coil becomes damaged due to a dirty air filter, it can freeze up. When it thaws, it will leak water into the house. This can easily be fixed and avoided by regularly changing out your air filters.

4. Low Refrigerant Volume

Just like a dirty air filter, having a low refrigerant volume in your AC unit can cause your evaporator coil to freeze, then unthaw and leak water into your home. One sign that your refrigerant volume is getting low is noticing when your home doesn’t cool down as it should.

The next time you notice your AC unit is leaking inside of your home, be sure to consider these four reasons. If the problem resides with your air filter, make an easy change of filters and the problem should go away on its own.
