No cool upstair system. Check and find air conditioner fail due to low charge. Check and find media coil badly rusted and leaking charge. Test and find compressor operating stress with high amp. System voltage absorption also weak. Suggest customer to upgrade system, customer want to wait. Customer want to repair system. Recharge system with sealer HJ8B. System operating at this time. Clean coil for customer due to coil dirty and causing high head pressure. If charge continues to leak out will need to replace cooling system. Test downstair system for customer, find system operating but have worn part due to age, high amp on compressor, weak voltage absorption and minor pitted on voltage distribution. Need to keep check on system. Suggest plan to help maintain system.
