Inverter split air conditioners generally require more frequent cleaning of condensers and evaporators compared to non-inverter split air conditioners due to a few reasons:
Increased runtime: Inverter air conditioners operate at variable speeds, adjusting the compressor's speed to maintain a consistent temperature. They typically run for longer durations at lower speeds compared to non-inverter ACs. The extended runtime allows more time for dust, dirt, and debris to accumulate on the condenser and evaporator coils, reducing their efficiency.
Lower airflow: Inverter ACs often have a lower airflow rate compared to non-inverter models. The reduced airflow can result in slower heat transfer and less efficient cooling. It also makes the condenser and evaporator coils more susceptible to dirt buildup, as the lower airflow may not dislodge debris as effectively.
Finer coil design: Inverter ACs tend to have coil designs with smaller and thinner fins, which enhance heat transfer efficiency. However, these smaller fins can be more easily clogged by dust particles, reducing the airflow through the coils and impairing performance. Regular cleaning is necessary to maintain optimal heat transfer and prevent any blockage.
To ensure the proper functioning and energy efficiency of an inverter split AC, it's important to clean the condenser and evaporator coils regularly. This can be done by removing any accumulated dirt, dust, or debris using a soft brush or a vacuum cleaner. It's recommended to follow the manufacturer's guidelines and instructions for cleaning and maintenance specific to your air conditioner model.
