Yes, regular cleaning can meaningfully reduce the electricity consumption of an aircon, as a unit with clean coils, filters, and fans operates at its designed efficiency level and does not need to run the compressor harder or longer to achieve the desired cooling effect. Studies and real-world experience consistently show that a heavily soiled aircon can consume 10 to 25 percent more electricity than a clean one of the same model and capacity, a significant difference when aircons are running for eight or more hours a day in Philippine households. Keeping the aircon clean is one of the simplest and most cost-effective ways to reduce monthly electric bills without sacrificing comfort.
