Why Is Water Leaking from the Air Conditioner and into the House?

One of the most common air conditioning issues is also one of the most damaging: a leaky system. Water can leak from an air conditioning system and into a home. Depending on the position of the indoor portion of the unit, it may leak into a room of the home and damage valuables or the walls, cabinetry, or flooring. So why is there water in your air conditioner, and how does it get out?

Air Conditioners and Humidity Control

Air conditioners don’t actually “create” cool air in the same way that a heater generates heat. Instead, they remove heat from the air that the blower fan sucks up from around the home. This air blows over an evaporator coil and, as refrigerant moving through the coil turns into a gas, it absorbs the heat from the air. This cools down the coil, and any water vapor in the air (humidity) collects on the coil.

The water should then drip down into a condensate drip tray, where it either flows into a drain via gravity or with the help of a condensate pump. When everything is working properly, this allows you to feel cooler due to lower humidity levels in the air.

When the System Won’t Drain

But if the condensate drain system goes unchecked for a long period of time, it could develop issues. One of the most common problems is a clogged condensate drain, which can cause water to backup into the home. If you schedule annual air conditioning maintenance with professionals, your technicians should check the drain and clean it out as necessary. Other common problems include holes in the condensate pan, a pan that is improperly positioned, or a broken condensate pump. In any case, you’ll want a professional air conditioning repair technician to make the final diagnosis.
