Completed system tune up. Checked pressures, volts, amps and all electrical components. Checked evaporator coil and drain line. Found dual run capacitor well below factory specs and also found 2 pole contactor very rusted and corroded. Replaced capacitor with turbo 200 which carries a 5 year warranty, replaced contactor and signed customer up for taps annual maintenance membership. Used todays tune up as 1 of 2. Left system in good working order.
