Model # GSX16S241AA Serial # 1906210614 Completed a preventative maintenance on a 3 year old Goodman air conditioner that we installed. I changed the 16x25x1 filter supplied by the customer. After that I took a split temperature reading and it was 18 degrees. I also made sure the condensate pump was working. After that I performed a amperage readings on the compressor 4.5 amps and the condenser fan motor was at .77 amps the capacitor and contactor are both operating properly. The system is operating properly at this time
