Performed cooling tune up. Checked volts, amps, temperature splits, refrigerant pressures including superheat and subcool, checked capacitors, contactors, blower wheel, filter is clean, tightened electrical, noticed the company that installed it jumped the 25 Amp breaker to 60 Amp breaker overloading the 60 Amp breaker so I turned off the extra 25 Amp breaker and showed the homeowner. Capacitors tested in range, contactor contacts look good, unit is working good at this time. Needs new wire to 25 Amp breaker in furnace, they jumped it off the 60 Amp circuit
