AC cool check completed on 11 year-old horizontal Carrier system. Drain line has been flushed and treated. Condenser coils have been cleaned. I found that the condenser fan motor was leaking lubricant. I presented options for repair to the homeowner and she decided to replace the condenser fan motor today. I drove to the parts house and picked up the part. I then returned and replaced the condenser fan motor with the new one. I function tested the system. All other mechanical and electrical components are within manufacturer specs. No other major issues were found. The system is cooling properly at time of departure.
