Common Causes of an AC Leak

Keeping your air conditioning unit in prime condition is crucial. Now that spring has begun and summer is quickly approaching, you want to be sure your AC is working at its best. Unfortunately, your AC can become overworked during warmer months which can lead to a variety of issues, one of them being a leak. AC leaks can be a frustrating, often expensive mess. Knowing what causes these leaks is the first step to preventing them.

What can cause your AC to leak?

A Damaged Overflow Pan
Check your AC overflow pan to be sure there are no signs of problems, such as cracks or holes. This damage can be caused by extreme temperatures and everyday wear and tear. When your overflow pan is damaged, leaks can occur.

Drain Line Back-Up
This is a very common cause of a leak. Most of the time a drain line can get clogged with water or dirt. The water will go back into the pan with nowhere to go. The pan is only designed to hold so much water so when it is full it will overflow.

Clogged Air Filter
Another reason your AC unit may leak is due to a clogged filter. A dirty air filter blocks air from penetrating through the filter. When air cannot get through the filter it will begin to freeze. Once this frozen water starts to melt, water will start to drip. Be sure to change your air filters on a regular basis to prevent this.

Low Refrigerant
Check your refrigerant to be sure that it is full. Your AC unit can begin to leak when the refrigerant runs low. When it starts to get low the unit can begin to freeze. Once your unit is off than the frozen water will start melting. This can cause water to down to your ceiling. If you do not take care of this immediately, it can lead to water damage.

Every Day Wear
As your AC unit ages, it will start experiencing some issues naturally. The seals on the service valve and the joints of your system can start to deteriorate after time. This can lead to a leak. Check your system periodically, if you notice certain parts that are aging then replace or repair them.
