Have you noticed water spots around the indoor cabinet of your air conditioner? Have you seen a large puddle of water next to your outside air-conditioning unit for several days? While a small amount of water near your air conditioner’s drainpipe is normal, if the water leak is large or continues for more than a day, you may have a problem. Here are some common reasons why your air conditioner is dripping water.
Your air conditioner doesn't use water as part of the cooling process—a chemical blend called refrigerant moves heat from inside the home and releases it to the outside. Water is a byproduct of this process. As the evaporator coil inside the unit removes heat from the air, it also draws moisture from that air. The water condenses along the evaporator coil and drips off, collecting in the condensate pan. A pump removes the water through a drain. That's why you'll occasionally hear the sound of dripping water from inside an air conditioner. There are 3 common reasons to explain water leaking from your AC unit:
· The condensate drain has become clogged or has come loose or broken off from the pan, causing the pan to overflow.
· The condensate pump has failed and is no longer removing water from the pan, leading to an overflow.
· The evaporator coils are frozen.
Issues with the condensate drain line are the most common cause of an air conditioner leaking water inside the home. Algae or fungi can clog your AC condensate drain line and will need to be cleaned. The condensate drain line can also become separated from the drain pan, allowing water to escape through the bottom of the pan. If your unit is older, the drain pan, which is located underneath your evaporator coil and collects any condensate from your indoor unit, may be damaged or rusted through. You’ll need to call for AC service to have the pan replaced.
The condensate pump supports water removal from the air-conditioning system. Due to the continual presence of water, mold can grow inside the unit, causing the pump to become clogged. When the condensate pump fails, water can't be removed from the system. As a result, water spills out from the drain pan, flooding your attic or basement.
If your air filter is dirty, air can’t pass through as easily, causing the evaporator coils to freeze up. The refrigerant flows through the evaporator coils and requires proper airflow to absorb heat. If the airflow is restricted, ice will form and drip water. Dirty coils, blocked vents or registers, a broken blower motor, or lack of refrigerant can also cause evaporator coils to freeze. If the evaporator coils are frozen, the refrigerant can no longer remove the heat from your home. This can lead to warm air or no air and potential problems with your compressor. You can help avoid frozen evaporator coils by replacing your air filter every 30 to 90 days and by keeping all air vents and registers open and uncovered. If you notice a frozen evaporator coil, turn the unit off immediately and don’t turn it on again until the problem has been fixed.
