Came out today to perform one system HVAC service call. On arrival customer stated that their unit was coming on and then would shut off shortly after. Upon inspection of the unit found the inside of the unit to be very dusty and dirty, the blower wheel was very dirty, the blower capacitor was bad and the blower motor was very dirty and pulling high amps. Upon further inspection found lots of rust on the major heating components. Upon speaking with customer they declined any repairs at this time. At this time system is up and running.
