Why Is My Air Conditioner Leaking Water?
For some reason or another, sometimes the air conditioning unit may start leaking water. This problem occurs because the AC unit contains an evaporator coil that cools the warm air blown over it. Sometimes, this part of the system causes condensation or moisture that forms on the coil. The excess of moisture in this area makes the AC ducts or vents leak water.
Here you will find 5 reasons why your AC might be leaking water:
Reason 1: Clogged Drain Lines
Clogged drain lines form one of the more common reasons for AC leaks. Mold, dust, dirt, and ugly sludge can build up over time and prevent vapors from escaping. If this happens, you will have to unclog the drain line through a professional cleaning service. There are also a couple of DIY unclogging methods you could explore. For example: using a wet/dry vacuum on the clogged line you could suck up most dirt preventing airflow. However, you might accidentally break the ductwork, or the drain might be in a hard-to-reach area (like the attic or roof). The best way to get this done safely is by calling a professional that has all the standards equipment and the experience needed.
Reason 2: Damage Air Pan
The air pan is a central part of the air conditioning system. As the warm air goes through the cooling coils, moisture accumulates on the coils and drips into the condensate pan. If this pan becomes clogged, rusted or damaged, you will have to replace it. By replacing this, you will prevent water from leaking into places where it can damage other components of the HVAC system.
Reason 3: Dirty Air Filters
Having dirty air filters blocks airflow over the evaporator coil. When this happens, the evaporator coil can get too cold and freeze. When the frost melts, the excess of water goes to the air pan, which may not be able to sustain this amount of water. Checking your air filters regularly will prevent this problem to happen. You should replace filters about every 1-3 months.
Reason 4: Low Refrigerator
Lower refrigeration will lower the pressure in the AC system. When this happens, the coil melts and the water can overflow into the drain pan. You may have an abnormally low air pressure if your system doesn’t cool correctly or you hear a bubbling noise. Depending on the situation, you may have to replace the entire AC unit or repair the leak.
Reason 5: Too Cold Outside
When the cold weather sets in suddenly, you may notice problems in your HVAC system. If the outside temperature drops below 60 degrees Fahrenheit, the cooling coil may ice up during the night and melts in the morning. These types of drastic change could damage the whole AC unit or flood components. To help solve this problem, you should unplug the AC at night and turn it on in the morning.
You should routinely check your system for general maintenance issues. In fact, Beaufort Air offers a scheduled yearly HVAC checkup yearly HVAC checkup at a discounted rate. You don’t want to leave a system leaking for too long as you won’t get any heating and cooling. Not to mention, you risk electrical shock! Water and mechanical wiring don’t mix!
