What Are The Causes Of Water Leakage In Air Conditioners?

There's always a reason for everything. If there's water leaking in your AC, then there must be a reason behind it. There can be many factors; the most common are

Air Filters

When your air filters are dirty and clogged, they won't be able to pull the air into the air handler. That ultimately results in poor-quality cooling because there is no way for the cold particles to pass, which makes the evaporator coil freeze.

The frozen coils melt gradually, and the water starts leaking from your air conditioner.

You need to replace flat filters once or twice a month and pleated filters once or twice in three months. Replacing filters is good for IAQ (Indoor Air Quality) and efficiency.


The evaporator coil can freeze if the air conditioning system has low freon levels. If there's ice on the line that connects indoor and outdoor units, it means you have low refrigerant. You can fix the refrigerant leak by getting help from a professional

Disconnected Or Blocked Drain

If the drain pipe is disconnected or clogged. You can face some major water leaking from your air conditioner. A good way to unclog the drain is to use a vacuum to remove trash or residue stuck in the drain.

Broken Pump

Broken Pump

To move the water from the condensate plate, pumps are used. If that pump is broken or clogged, the water will start dripping from the air conditioners.

Disconnected Channel Line

If your A/C's channel line isn't introduced correctly, then it will cause the dripping of water. There can be many reasons for its disconnection, e.g., vibration; etc.

Frozen Coil

Frozen coils are the major cause of water leakage. They get frozen mostly because of uncleaned filters.
