Why Air Conditioner Leaking Inside?

  • Clogged condensate drain line

A clogged condensate drain line is the most common cause of water leaking from air conditioner into home.

If the drain line gets clogged with dust, dirt, sludge or mold, that water backs up into your home. In that case, you’ll need to unclog it. There are multiple unclogging methods, like using a wet/dry vac on the condensate line.

But the surefire way is to have a professional use a special vacuum to suck the blockage material out

  • Damaged/rusted drain pan

Got an old air conditioner (12-15 years)? The drain pan may be damaged or rusted through, so water just falls right through. You’ll need to replace the pan.

  • Broken condensate pump

Is your furnace and indoor AC unit installed in the basement? If so then there is a condensate pump that pumps the water outside. But if the pump breaks, the water isn’t being pumped outside anymore. You will need to repair or replace the pump.

  • Dirty air filter

A dirty air filter blocks airflow over the evaporator coil. When that happens, the evaporator coil gets too cold and freezes over. When it melts, it drips an excess amount of water that the pan may not be able to handle.

  • Low refrigerant

Similar to a dirty air filter, low refrigerant will lower pressure in the AC system, causing the evaporator coil to freeze over. When the coil melts, water overflows the drain pan.
