Why Is My Air Conditioner Leaking Water?

air conditioner leaking water out of vents

While summer will come to a close soon enough, your AC system is still working overtime to keep your home cool in blazing temperatures. This hard work can take a toll on your air conditioner, and you could start to see water leaking from your system. 

This leakage can be a result of multiple factors affecting your AC unit. Let’s take a look at some reasons your system is leaking:

Dirty Air Filters

Be honest with yourself. When was the last time you changed your air filters? We recommend you change them every 1-2 months, but we understand that life gets in the way. Dirty air filters can cause leakage to develop due to the fact that your system is working harder. Dirty filters can also block the airflow that is supposed to go over your unit’s evaporator coil. This can freeze the coil resulting in water leaking from your AC.

Low Refrigerant Levels

When your levels drop due to a refrigerant leak, so does the air pressure of your air conditioning unit. Without much pressure, it will cause your evaporator coil to freeze and will begin to leak water out of your AC.

Clogged Drain Lines

Your drain lines are connected to your unit’s drain pan, which carries water to the outside of your air conditioner. When your drain lines clog from dirt, debris, and other contaminants, it can block water flow. If the blockage is so severe, it can stress the connection to the drain pan causing wear and tear resulting in your AC dripping water. 

Issues With Condensate Pump 

If your condensate pump begins to malfunction or even break, it can cause leaking. Since these pumps are located in an attic or basement, they can cause damage to your home if not repaired promptly. Your condensate pump can also clog due to the buildup of water that can form mold and mildew.
