One of the most common requests for air conditioning repair is due to the air conditioning unit leaking water. An air conditioner is designed to filter humid and warm air that inside your home through a condenser unit that is inside the air conditioner, and cycle dryer, cooler air into your home. This process is what keeps your home cool during the summer heat; unfortunately, the humidity inside your home can cause the air conditioner to leak water from a variety of different reasons. Here are three reasons why your air conditioner may be leaking water and how to repair the problem.
1. The Overflow Pan
In many situations, water is leaking from an air conditioner because of a problem with the overflow pan, which is used to catch the condensation from the air conditioner unit. If you notice a leak the first step is to inspect the overflow pan for any damage. Be sure to check along the outside edges, each corner and directly above the wettest spot. Small cracks and holes can often be patched with epoxy glue, but it is best to go ahead and replace a damaged overflow pan.
2. Clogged Air Filter
One of the most common causes of water leaking from your air conditioner is a clogged air filter; this is also one of the easiest things you can do to prevent the problem. When the air filter gets clogged with dust and dirt, it blocks the airflow over the evaporator coil, which causes the coil to get too cold and it freezes over. As the ice melts from the coil, it causes more water to drip in the overflow pan than the pan can handle. Changing the air filter once a month may help to prevent this problem.
3. Clogged Condensate Line
A clogged condensate line is generally the most common cause of an air conditioning leak. The condensate line drains from the overflow pan either directly into a drainpipe or to the outside. If the line gets clogged the water backs up and floods the overflow pan, causing the water to leak out.
Most air conditioner units are equipped with a water-overflow cutoff switch that automatically shuts the unit down if a clog in the condensate line is detected. If the air conditioner suddenly shuts off, it is best to contact a professional HVAC company to make the repairs. Having routine maintenance on the HVAC unit generally includes cleaning the line, which will prevent clogging.
The best way to prevent the risk of your air conditioning unit from leaking is with regular maintenance. Homeowners can do many of the maintenance tasks themselves, such as changing the air filter monthly. Many HVAC companies offer maintenance service plans that include routine inspections of the unit as well as cleaning the lines and checking for damages.
