Commercial aircons, including cassette-type units, ceiling-mounted systems, and centralized air conditioning systems used in offices, restaurants, hotels, and retail spaces in the Philippines, should be cleaned more frequently than residential units due to their continuous operation and the higher volume of people and activity they are exposed to. A monthly inspection and filter cleaning is recommended for most commercial setups, with a thorough professional cleaning of the coils, drainage system, and fan components scheduled every two to three months. For businesses in the food service industry or those operating in dusty or high-traffic environments, even more frequent servicing may be necessary to comply with health and safety standards and to prevent system breakdowns that could disrupt operations.
