Water Damage Caused By Air Conditioner By Water Damage Advisor Posted on July 18, 2015March 19, 2020 Air conditioners can cause water damage if not properly maintained. When a unit is working at its peak efficiency it can collect anywhere between 10 to 20 gallons of water a day. Because most of the unit is typically tucked away and out of sight, many times you won’t be able to see the amount of damage until it has already accumulated into major water damage. Common Causes of Air Conditioner Leak Although there are a few different reasons why an air conditioner might leak, here are two of the most common causes of leaks in A/C units: Clogged Drain Line Ideally, water will drain off the condensation coil into a collection pan, after which it is then disposed into the sewer system. But if a drain becomes clogged it can overflow and lead to damaged floors, carpeting, as well as creating unhealthy molds. If you’re ever unsure about the type of mold you have, you should always seek an expert’s opinion. Condensation Pump Malfunction A dirty condensation pump can cause water to leak. The excessive build-up of water can lead to the growth of mold and mildew inside the unit which can lead to further health issues if not taken care of within an appropriate amount of time. Most mold isn’t that harmful to humans or pets, but if you ever suspect black mold, you should always reach out to an expert.
