Before we delve into the potential causes of water leakage, let’s take a moment to understand the basics of how your air conditioning system works. This knowledge will give you a better grasp of the potential issues that may arise and will help you troubleshoot more effectively.

An air conditioning system operates by removing heat and humidity from the indoor air, leaving behind cool and dehumidified air. This cooling process primarily occurs in the evaporator coil, located in the indoor unit of the AC system. During operation, warm indoor air passes over the evaporator coil, and the refrigerant inside the coil absorbs the heat, resulting in the cooling of the air.

As the warm air passes over the chilled coil, water vapor in the air condenses into liquid form on the coil surface. This liquid water is then collected and channeled out of the system through a drain line, usually connected to a condensate pan and eventually leading to an exterior drain or a drain pump. However, in some cases, issues may arise that cause the water to leak from the AC unit instead of being properly drained away.

Now that we have a basic understanding of how air conditioners work, let’s explore the common causes of water leakage and how to address them. By following these troubleshooting steps, you can prevent further damage to your system and ensure the efficient operation of your air conditioning unit.

Before diving into the causes of water leakage, it’s important to have a solid understanding of the different components that make up your air conditioning system. This knowledge will help you identify and troubleshoot issues more effectively.

An air conditioning system typically consists of two main units – the indoor unit and the outdoor unit. The indoor unit, also known as the evaporator unit, is responsible for cooling and dehumidifying the air. It contains the evaporator coil, which is crucial in removing heat and moisture from the indoor air.

The outdoor unit, also known as the condenser unit, houses components such as the condenser coil, compressor, and fan. The condenser coil is responsible for releasing the heat absorbed from the indoor air, while the compressor circulates the refrigerant between the indoor and outdoor units, facilitating the cooling process.

When your air conditioner is turned on, the compressor in the outdoor unit pressurizes the refrigerant and sends it to the indoor unit. The refrigerant travels through the evaporator coil, absorbing heat from the indoor air, and then returns to the outdoor unit to release the heat. This continuous cycle helps maintain a comfortable indoor temperature.

During the cooling process, condensation forms on the evaporator coil as the warm air passes over it. This condensation drips down into a condensate pan located below the coil. From there, the water is directed to a condensate drain line and carried away from the unit.
