Keep reading to learn more about why your AC vent is leaking water and what you can do to stop it.

Common Causes of Water Dripping From Your AC Vent

Here’s what might cause water to start dripping from your AC vents.

Condensation Buildup

If you have water dripping from any AC vents, condensation is the most likely cause. When warm, moist air comes in contact with a cold surface—like an AC vent—condensation forms. That’s why dripping vents are extremely common in humid climates like Kentucky. Homes with poor insulation or an improperly sized AC unit are also prone to dripping vents.

Clogged Condensate Drain Line

The condensate drain line is a hose that moves water from the AC unit to other areas of your home. When this line gets clogged with debris, water starts to accumulate and can cause flooding. If you have a downflow system, this water could make its way to the AC vents.

Frozen Evaporator Coil

The evaporator coils—which are found inside the blower or air handler—absorb heat from indoor air as part of the cooling process. If these coils get wet and freeze, air has no way to get through. You run the risk of the coils leaking and causing other problems.

Improper Installation

Proper sizing and proper installation of an AC unit are essential. If your cooling system is installed incorrectly, the drain pan or even the entire unit could rest at an uneven angle. Even the slightest tilt can cause condensation to accumulate and drip from air vents in your home.

How to Stop Water Dripping From Your AC Vent

Once you notice water dripping from an AC vent, you should act fast to fix the problem. Here are some ways to stop the dripping.
  1. Regular maintenance: Routine maintenance is the easiest and most effective way to prevent common AC problems, such as water dripping from vents. Talk with your local HVAC technician to create a maintenance schedule that works for your home, which should include cleaning the vents at least once annually. If you live in an area with high humidity levels or a lot of dust, you may need to clean them more frequently.
  2. Clearing the condensate drain line: Flush vinegar down the condensate drain line twice a year to eliminate any mold or algae buildup that could be clogging the line and preventing water flow.
  3. Adjusting humidity levels: A high humidity level can cause condensation to accumulate and drip from the vents. You can stop this problem by adjusting the humidity level in your home to keep it balanced.
  4. Checking for refrigerant leaks: A refrigerant leak can cause your AC system to stop producing cool air, which would result in higher humidity levels and more condensation. Check your system regularly for refrigerant leaks, or hire an HVAC technician to do it for you.

Our Top Prevention Tips

Dealing with dripping AC vents once is enough; the last thing you want is to deal with the same problem again. Here are a few tips we recommend following to keep condensation levels low and your vents dry.
  1. Regularly changing air filters: Dirty air filters can cause accumulated condensation from the drain pan to freeze the evaporator coils. When the unit is turned on, the coils thaw, and the water drips through the air vents. Replacing the filter quarterly will prevent this from happening.
  2. Ensuring proper insulation: Poor insulation can cause built-up condensation to make it sway through your air vents. Check the condition of the insulation behind your vents—or if there even is any. If there’s no insulation or the quality of the insulation is poor, get new insulation installed. It will absorb any condensation before it gets to the air vents.
  3. Scheduling professional inspections: You should have your AC system inspected once a year to identify any issues and make the necessary repairs. This simple step will prevent water from dripping from the vents along with other problems that can decrease the efficiency and lifespan of your AC system.
  4. Monitoring for early signs of issues: Keep tabs on your AC system throughout the year to know when something goes wrong. As soon as you notice a problem, contact a trusted GreenBox technician to make things right.
