3 Reasons Water is Dripping From Your AC Vent

3 Reasons Water is Dripping From Your AC Vent

Water dripping from anywhere it shouldn’t is never a good sign. Mold growth, inflated utility bills, drywall and paint damage, are only a few of the problems accompanying water leaking from an air conditioning vent in the ceiling. Thankfully, there are a few ways to troubleshoot the leak and fix the problem before it causes extensive damage to your home. Read on to learn why your AC vent is leaking water and what you can do about it.

1. Repairing A Clogged Drain Line

As a homeowner in the Saint Petersburg and Clearwater, Florida area, a clogged drain pipe is one of the most common problems causing water leakages around your air handler. Being surrounded by water creates humid conditions allowing 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. Is water leaking from the air handler or your AC vent? Determining the source of the leak is the first step to fixing the problem. 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. 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. 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. Fixing a Refrigerant Leak

Your A/C vent can also leak water when Freon 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. 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. Locate your evaporator coil and assess the exterior for frost or ice indicating a leak.

Step 2. 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. Contact Climate Design immediately if you believe your refrigerant is leaking.

3. Changing a 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. A dirty air filter can cause the AC 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 a new air filter:

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