Tech performed maintenance per service agreement. Tech found compressor not running on arrival. Capacitor was reading good and compressor was getting 240v. Tech found oil residue in drain pan. Homeowner had leak freeze put in last year. Tech suspects system is low on refrigerant. Tech contacted office to get help from a service tech. Homeowner did not have water available. Tech will have to return to clean coils. System is not operating properly at this time. Turned over to service tech.
