Came out to perform preventative maintenance on AC system. Customer met me at the front door and we discussed maintenance being performed today, filters and anything that I can do for her. Customer stated that she had the gate open for the AC in the back, and that she would change the filters inside if I could provide them. Gave customer filters she needed and proceeded to check the AC. Disassembled the AC system and cleaned the condenser coil thoroughly. Inspected the condenser coil, fan motor, compressor, fan motor, contactor, capacitor, electrical connections and overall condition of equipment. Found contactor pitted and wearing out. Customer cycled system on from thermostat and I checked amps, temperatures and pressures of the system. Found unit had high start up amps, reading 127 and the Lock Rotor Amp limit on the compressor is 130. Considering the age of the equipment, I highly recommended customer add a hard start kit to the system to help reduce the amps on start up. Customer
