Reasons For Air Conditioner Water Leakages Inside My Home

With summers overhead, air conditioners are constantly running. This kind of excess functioning can cause hiccups or damage to the system over time. Even with a recent AC installation in Folsom, CA, homeowners face minor air conditioner repairs. Amongst the long list, water leakage in the air conditioner is a common issue.

While a small amount of leakage is normal, excess dripping can be alarming and puzzling. Here are some reasons why your air conditioner might be leaking water inside:

Old Condensation Pan

A condensation pan is responsible for collecting the condensed water. Over time, the pan gets old and rusted, resulting in water leakage. Replacing the pan is a quick solution.

Dirty Air Filters

A common cause of water leakages is dirty or clogged air filters. These clogged air filters freeze the evaporator coils resulting in excess water spilling indoors. Avoid leakages through frequent filter cleanings and changings

Low Refrigerant Volume

When the volume of the refrigerant in your AC unit decreases, the pressure in the unit decreases as well, causing the evaporator coils to freeze. Consequently, the unit gets wet and starts leaking water. Ensure to keep a check on your refrigerant levels, indicated through the cooling of your home.

Clogged Drain Lines

The condensate drain lines encounter a lot of debris, dirt, and mold that gets accumulated, clogging the drain line. With a clogged drain line, the water that is supposed to drain out is left in the system. As a result, the water leaks into your home. Contacting an air conditioner contractor helps in cleaning the drain lines and fixing the leak.

Faulty AC Installation

If a new air conditioner installation or recent repair is done incorrectly leads to water leakages. Often, gaps between the units expose the condensate tray or the drain pipe. This, in turn, causes the condensed water to drip into your room. Thus, being vigilant during and after the installation or repair of the air conditioner is essential to avoid this problem.

Broken Float Switch or Condensate Pump

If the air conditioner unit is placed in the basement or the attic, draining the water becomes difficult. A condensate pump is responsible for removing the water from the system. When the condensate pump reservoir is filled with water, the float switch turns on, draining the water outside. A faulty or broken condensate pump and float switch hampers the draining system and leaks the water into your home. To fix a broken condensate pump, contacting a technician is necessary.
