II. Understanding the Split AC System
Before we dive into the common causes of water leakage from split AC units, let’s take a moment to understand how these systems work. A split AC consists of two main components: the indoor unit and the outdoor unit.
The indoor unit, also known as the evaporator unit, is typically installed inside the room you want to cool. It contains the evaporator coil, which is responsible for absorbing heat from the air. The outdoor unit, or the condenser unit, is usually placed outside the house and houses the condenser coil and the compressor.
When you turn on the AC, the compressor in the outdoor unit pumps refrigerant to the evaporator coil in the indoor unit. The refrigerant absorbs heat from the indoor air, causing it to cool down. As the warm air passes over the evaporator coil, the moisture in the air condenses and collects on the coil.
This condensed moisture, also known as condensate, is then drained away through a drainage pipe. However, when something goes wrong with the AC system, this condensate may not be properly drained, leading to water leakage. Now, let’s explore the common causes of water leakage from split AC units.
III. Common Causes of Water Leakage from Split AC
A. Clogged or Dirty Air Filters
One of the most common causes of water leakage from split AC units is clogged or dirty air filters.
