Techs arrived on site and performed ac tune up of commercial package unit. Cleaned coils and electrical cabinet. Tested electrical components. Found the condenser fan motor to be leaking oil. Start caps are okay and within range but reading low. Condensate line had broken off and is leaking onto rooftop. Filters need to be changed. System is 2 stage but currently wired for 1 stage. Need to upgrade thermostat for 2 stage. Will send estimate for quarterly commercial service.
