I performed diagnostic service on York Air Conditioning Unit. I determined that that the system is low on refrigerant and also tested dual capacitor and it is reading low and will need replaced in the near future, also the condenser coil was extremely dirty and rinsed off and cleaned. I informed owner of leak and explained about leak search/repairs /replacement options. He wants to charge the system for today and hope it lasts this season. He will look into replacement next season. System operational and cooling at departure.
