To tackle the problem of dripping air-conditioners, the Food and Environmental Hygiene Department (FEHD) has implemented a scheme in certain private housing estates since 2005 to solicit participation from respective property management agents (PMAs) in handling complaints on dripping air-conditioners during summer season. Staff of participating PMAs, while performing routine management duties in the estate, will help to identify the source of dripping and advise the occupier concerned to rectify the problem. If such effort of the PMA cannot resolve the complaint, FEHD will intervene by taking up the case for follow-up action. Through the high-quality customer service provided by the PMAs, the harmonious relationship among occupiers can be effectively maintained, and the interaction and active cooperation between occupiers can be strengthened to assist in identifying the source of water dripping from the air-conditioners.
