The Common Causes of Water Leaking From AC Unit

Before we explore how to tackle this problem, let’s take a moment to understand how an air conditioner operates. 

Nowadays, air conditioning systems consist of two units – indoor and outdoor. The indoor unit contains a coil that cools the warm air as it flows over it, creating a comfortable indoor temperature. As the air passes over the coil, water droplets form, similar to a cold glass of water. This moisture is collected in a drain pan and then drained outside your home via a condensate drain line.

In general, you shouldn’t have issues with your air conditioner leaking water indoors. However, when things go awry, you might find the nightmare of your AC unit dripping water

Here are the primary culprits:


Clogged or Dirty Air Filters

When the air filters within your AC system become clogged or excessively dirty, they obstruct the airflow. This reduced airflow can cause the evaporator coils to become too cold. As a result, excess condensation forms on the coils, leading to water leakage from the AC unit.


Blocked or Disconnected Drain Lines

The condensate drain line is responsible for carrying away the water produced during the cooling process. If this drain line becomes blocked by debris, algae, or mold, or if it becomes disconnected, the collected water cannot properly drain, causing it to overflow and leak from your AC unit.


Refrigerant Issues

Refrigerant is responsible for absorbing and releasing heat during the cooling process. A refrigerant leak can lead to a drop in the evaporator coil’s temperature, resulting in excess condensation and water leakage when the coil thaws.


Frozen Evaporator Coils

If there is inadequate airflow over the evaporator coils or a refrigerant issue, the coils can freeze. When these coils are frozen, they cannot properly dehumidify the air, which leads to excess condensation and water leakage when they thaw.


Damaged Condenser

The condenser is the outdoor unit of your air conditioning system which plays an important role in releasing the heat collected by the indoor unit. If the condenser is damaged, it can lead to a leakage of water from the system.


Improper Installation or Maintenance

Faulty installation or inadequate maintenance can result in various problems that disrupt the normal operation of your AC system. Issues like improper unit tilt, loose components, or inadequate insulation can all contribute to water leaking from your AC unit.


Signs and Symptoms of AC Water Leakage

Knowing the signs why your AC is leaking water is crucial for prompt intervention. Look out for these telltale signs:

Water Pooling Around the AC Unit

Visible water puddles around your AC unit are a clear sign of a problem. Don’t ignore it; it could lead to damage to your flooring and even structural issues if left unchecked.

Musty Odors in the Home

Excess moisture from a leaking AC unit can promote mold and mildew growth. These fungi produce distinct odors that can permeate your living space, affecting your indoor air quality and creating an uncomfortable atmosphere.

Decreased Cooling Efficiency

If you notice that your AC isn’t cooling your home as effectively as it used to, it could be due to water leaking from AC unit. Water accumulation within the unit can disrupt the cooling process, making your air conditioner less efficient. Addressing this issue promptly can help restore your AC’s performance and maintain a comfortable indoor temperature.

Unusual Sounds or Vibrations

Gurgling or splashing sounds coming from your AC unit are not normal and can be indicative of water drainage issues. When water isn’t draining properly, you may hear these sounds as water moves around within the unit. Vibrations or noises you haven’t heard before should prompt an investigation to identify the source of the problem.
