5 Common Causes of Air Conditioner Leak

In addition to keeping your home cool, your air conditioner controls humidity. Evaporator coils condense warm air coming into the unit and remove any humidity. This moisture ends up in a condensate drain line that removes water from your home.

If your AC is dripping water, that means something stopped the moisture from draining properly. Here are five reasons why this happens.

Water droplets on the air conditioner surface due to condensation When hot air comes into contact with the water vapor in the ducts, it condenses into water droplets called ductwork sweating.

Excessive Condensation

If an excessive amount of condensation builds up, water will eventually drip from the AC vents instead of its intended place. Condensation can build up if there is a leaky roof or inadequate insulation. Check the roof for any leaks and install ductwork insulation.

Frozen Evaporator Coils

The evaporator coils can freeze if the air filter becomes clogged or refrigerant leaks. With frozen coils, the moisture builds up until it eventually leaks out. If you have a clogged air filter, clean it or replace it. For a refrigerant leak, contact your HVAC technician to fix the problem.

Obstructed or Disconnected Condensate Drain Line

Dirt or debris from the moisture in the unit can gradually clog the condensate drain line and lead to a leak. The drain line can also disconnect, causing water to drip water from the AC. The only solution is for an HVAC technician to reconnect the drain line.

Broken Condensate Pump

The condensate pump removes the water from the AC unit, but if this part breaks, water has no way of draining, leaving you with an AC leaking water. Your HVAC technician can repair the damage or replace the part entirely.

Damaged Drain Pan

The drain pan helps prevent leaks by catching moisture from the AC unit. If the drain pan is damaged, it can rust and crack, causing water to leak out.
