Why Your A/C is Leaking Water & How to Fix It
Finding a puddle of water near your cooling equipment requires immediate attention. If you are asking yourself why your air conditioning is leaking water, the issue is usually caused by a drainage blockage or a frozen component. Air conditioners naturally remove humidity from the air in your home as they run, and that moisture needs a clear path to drain outside. This guide explains the common reasons for an A/C leak, steps you can take to protect your property, and how to know it is time to call a professional for repairs.
Common Reasons Your A/C is Leaking Water
A leaking cooling system happens when normal condensation cannot exit your unit properly. The following issues are the most frequent culprits behind indoor water leaks.
Over time, dust, dirt, and algae can build up inside the PVC pipe that carries condensation away from your unit. As this buildup restricts the flow of water, the moisture backs up into your home. This is the most common reason homeowners experience an indoor A/C leak.
Your system features a drain pan designed to catch the water dripping off the evaporator coil. In older A/C units, this metal or plastic pan can develop cracks or rust. A compromised pan allows water to escape before it ever reaches the drain line.
Restricted airflow or low refrigerant levels can cause your evaporator coil to freeze solid. Once the system turns off and the ice begins to melt, the sudden rush of water overwhelms the drain pan, resulting in an overflow.
Immediate Steps to Take if You Find a Leak
Before calling a technician, you can take a few practical steps to prevent water damage to your floors and potentially identify the source of the leak.
Shut off your air conditioner at the thermostat right away. Stopping the cooling cycle prevents the system from generating any more condensation.
Thoroughly dry the area around your indoor unit. Removing standing water quickly protects your flooring, drywall, and nearby structural components from mold growth and rot.
A dirty air filter blocks the airflow your system needs to function. This restriction often causes the evaporator coil to freeze over. Check your filter and replace it immediately if it is clogged with dust. A clean filter can sometimes resolve the root cause of the freezing and leaking.
