Evaporator Coils

Evaporator coils play a crucial role in the cooling process of an air conditioner. Located inside the indoor unit, these coils absorb heat from the surrounding air. When warm air passes over the evaporator coils, the refrigerant within the coils absorbs the heat, causing the air to cool down. This cooled air is then circulated back into the room, providing a comfortable indoor environment.

Over time, the evaporator coils can accumulate dust, dirt, and other particles from the air. This buildup restricts the airflow and insulates the coils, hindering their ability to absorb heat effectively. As a result, the cooling efficiency of the air conditioner decreases, leading to reduced comfort and increased energy consumption. Regular cleaning of the evaporator coils is essential to maintain optimal cooling performance.

Condenser Coils

Condenser coils, on the other hand, are located in the outdoor unit of the air conditioner. These coils release the heat absorbed by the evaporator coils to the outside environment. As the refrigerant flows through the condenser coils, a fan blows air over them, allowing the heat to dissipate and cool down.

Similar to the evaporator coils, the condenser coils are also prone to accumulating dirt, debris, and even vegetation. This buildup acts as an insulating layer, preventing the coils from releasing heat efficiently. As a result, the air conditioner works harder to achieve the desired cooling, leading to increased energy consumption and potential damage to the compressor. Regular cleaning of the condenser coils is vital to maintain the overall performance and longevity of the air conditioning system.
