Air conditioners generate moisture as part of their operation. Normally this condensation is directed out of your home via a pipe. If your air conditioner is leaking moisture into your home, this is a sign of a problem. There are several reasons an air conditioner might be leaking condensation.

Air conditioner is rusted through

The drain pan in the air conditioner might be rusted through or otherwise damaged. If this is the case, you will need to replace the drain pan.

Drain line is clogged

There could be clog in the condensation drain line. Water can back up into your home if the pipe is clogged with dirt, dust, or sludge. You can try using a wet/dry vacuum on the drain line, or call an HVAC professional to clear the line with specialized equipment.

The air filter is dirty

The air filter could be dirty. When the air filter is dirty, the evaporator coil doesn’t get the air flow it needs, which can cause it to freeze. Then when the evaporator coil melts, it might generate more moisture all at once than your air conditioner deal with. If this is the case, replace the air filter. In general, the air filter on your air conditioning should be replaced every few months.

You have a broken pipe

The condensation pump could be broken. The pump is what directs the water out of the air conditioner into the drain line. You will need to have the pump repaired or replaced.
