Air conditioners should be serviced at least twice a year—before and after peak summer use. Regular servicing includes cleaning or replacing filters, checking refrigerant levels, inspecting electrical connections, and ensuring the coils are free from dust and debris. If not maintained, ACs consume more power, resulting in higher electricity bills and poor cooling efficiency. Additionally, clogged filters can lead to unhealthy indoor air quality. If you use your AC frequently or live in a dusty area, consider servicing it quarterly for optimal performance and long-lasting efficiency.
