Dealing With Water Dripping From AC Vents

3 Causes of Water Accumulation

There are several issues that could lead to water dripping out of your AC vents. If you notice this happening, it’s important to determine the cause of the problem and take action in a timely manner. Some issues can be resolved without professional assistance, and some will require an air conditioning professional to take a look.

Some of the most common issues that will lead to leaking air conditioning vents include the following.

1. Condensate Drain Line Issues

A condensate line in your AC system that is clogged can cause condensation around your vents. To determine if this is the problem, check the drip pan on the outside part of your air conditioner. If it is full, this is likely your issue. You can clean the drain line with a shop vac or call a professional.

2. Dirty Air Filters

If the air filters in your AC system are dirty, they can impede air flow. When this happens, it can cause frost to build up on the filter. When the AC unit is turned off, this frost will melt and end up dripping out of your vents. This problem can be fixed by replacing your dirty filters with new ones.

3. Poor Duct Insulation

Ducts that don’t have enough insulation will cause moisture to condense on them when the AC is running. This moisture will drip off after it is shut off. To resolve this problem, you can get fiberglass insulation batts at the store and wrap the ducts. Using R-11 or R-13 insulation will keep the moisture from condensing.
