When you notice water leaking from your air conditioning unit, especially those roof top units, know that it can pose a serious problem. Some dripping is normal. When an air conditioning unit develops condensation it will collect moisture and begin dripping. However, continual and excessive dripping typically points to a problem. Air Supply Heating & Air Conditioning would like to share what to do when you have a major leak and what could be causing the leaks to occur.
What to Do when You Have a Leaking Air Conditioner?
When you have excessive leaking from your air conditioner, it can cause water damage. To prevent water damage from occurring once you discover the leak, turn the air conditioning unit off. After you have turned off the unit, quickly clean any water that has entered your home. This may include wiping down the ceiling, walls and floor. After cleaning the water, you may want to call an HVAC technician to determine the source of the leak.
Causes of Excessive Condensation from Air Conditioning Unit
There can be a few problems with the air conditioner that can result in water leaking. In most cases it has to do with the drainage system or from dirty or frozen coils. Here is why:
Condensate Drain: One of the most common causes for water leakage is a problem with the condensate drain line. Often the drainage line goes through the home and routes to the outside. Condensation is normal and occurs often. As the condensation builds up, the water goes down to the condensate pan through the drain and then through the piping that sends the water out and away from the home. The condensate draining line can develop clogs and plug up. Once this happens, the water will eventually over flow resulting in a leak. Often the piping will need to be cleaned to allow proper water flow.
AC Drainage Pan: The drainage pan over time can corrode and rust, which allows particles to block the drain. Leaves and dust can also build up and block the flow in the drainage pan. It is important to have the pan checked and cleaned at least once a year to allow the condensation to drain correctly. If the rust causes small holes in the pan, the water can also leak through the small holes. If the pan drain gets plugged then the water can over flow. Make sure to have the condensate pan inspected during your HVAC annual service.
Dirty and Frozen AC Coils: If the evaporator coils get dirty they will begin to freeze up. The ice can build up in large amounts. When the ice melts, the water will leak into the home. The coils are not meant to freeze up and there is no drainage system for the ice as it melts. This can result in water damage.

Often water leaks from the air conditioning system can be prevented with proper maintenance. During annual maintenance the condensation drainage system is inspected as well as the coils. When needed, the HVAC components are cleaned and repaired to ensure proper function and without leaks.
