Portable Ac Unit Leaking Water

Understanding Portable AC Unit Leaking Water

When you find water pooling around your portable AC unit it can be concerning. This is often a result of condensation which is a natural occurrence when warm air meets a cold surface. The cold coils within the AC unit cause moisture in the air to condense into water droplets.

Causes of Leaks

Condensate Drain Blockage

Over time dust and debris can accumulate in the condensate drain leading to a blockage. This blockage prevents the proper drainage of water causing it to overflow and leak from the unit.

Incorrect Installation

Improper installation can result in the unit not being level causing water to collect in one area instead of draining properly.

Excessive Humidity

High humidity levels can lead to more condensation within the unit potentially overwhelming the drainage system.

Preventive Measures

Regular Maintenance

Clean the filters and condensate drain regularly to prevent blockages and ensure smooth water drainage.

Proper Unit Placement

Place the AC unit on a level surface to ensure proper drainage and prevent water accumulation.

Use of a Drain Pan

Consider placing a drain pan under the unit to catch any excess water and prevent damage to your flooring.
