Performed cooling maintenance on one heat pump system. Checked all electrical, mechanical and performance of the system. Cleared and treated the drain line and washed the outdoor coil. I found the outdoor condenser fan motor is showing signs of overheating. I informed the homeowner, and he chose to have the motor replaced at this time. I replaced the motor and cycled power at the thermostat. No other major issues were found, and the system is operational at this time.
