The 3 Most Common Causes of Water Dripping From AC Vent

Read on to learn why water is dripping from your AC vent and what you can do about it.

1. Clogged Drain Line

As a homeowner in Florida, a clogged AC drain line is one of the most common problems causing water leakages around your air handler. Being surrounded by water creates humid conditions that allow algae and bacteria to clog a drain pipe easily.

Troubleshooting your condenser unit for a clog is simple. If the drip pan is full or overflowing the condensate drain line is probably clogged. The blockage prevents water from flowing through the drain line, so the water ends up in the drip pan, where it eventually causes water to leak around the air handler.

Step 1. Determine the source of the leak. Is water leaking from the air handler or your AC vent? If you own a split ductless heating and air conditioning system, the air handler is located in a closet or the attic. The following image highlights the area where you would typically see leakage.

Step 2. Unclog your drain line. Now that you have determined where the leak is coming from it’s time to unclog the condensate drain line. Luckily, cleaning the condensate drain is easy. All you need is something you probably already have: vinegar.

Step 3. Empty your drain pan. A clogged drain line prevents water from flowing through the drainpipe out of your home. Your drain pan serves as a reservoir carrying water from the evaporator coil to the drainpipe. The following image shows how this part of your air conditioner functions, how to locate your drain pan, and how to empty it out.

2. Refrigerant Leak

Your AC vent can also leak water when Freon, also called refrigerant, levels are low. Low refrigerant levels will cause the evaporator coils to freeze and water in the drain pan to rise as the coil melts.

Let’s discuss the steps you can take to fixing your HVAC refrigerant leak.

Step 1. Locate your evaporator coil and assess the exterior for frost or ice indicating a leak. Do you see a layer of frost or ice on the evaporator coils? Water leaking from the ceiling air conditioner vent is one way to alert you of a frozen evaporator coil.

Step 2. Contact Climate Design immediately if you believe your refrigerant is leaking. An air conditioner leaking Freon poses a severe threat to your HVAC unit. If your unit continues to run in this condition, your compressor will burn out and leave you with a costly repair.

3. Dirty Air Filter

Air filters play a crucial role in a properly functioning air conditioner. Without them, all of the dander, dirt, dust and excess debris would fill the rooms in your home.

It is essential to change your air filter on a monthly basis.

Dirty air filters can cause your AC system to freeze up. As the ice melts, the condensation can drip down and out through the air vents.

If your condenser unit shows minor frost, replace your air filter and run your system as usual.

If there is significant frost or ice, call a professional heating, venting, and cooling company to schedule a service.

3 Signs you need to replace your air filter:

1. Decreased airflow
2. Excess dust in your home
3. Frost on your AC unit
