Co-op owner experiencing moisture in their floors

Co-op has installed an air conditioning / heating directly underneath my apartment and it is creating slugs of water under my floors which is affecting my health and sleep. It sounds like some sort of a pump. My complaint was dismissed by management and board and its not loud enough for city agencies to issue violation. Any advice as what can be done - some sort of circulation issue?  Floors are warm but only when bare feet walking on floor. What type of expert can I get to to resolve?
