Performed cooling maintenance. Checked electrical, mechanical and performance of the system. Cleared and treated drain line and washed condenser coil. Found the indoor blower wheel covered with mold and the condenser fan motor was leaking grease. Please see attached checklist for full tune-up details. Showed customer options for repairs and they chose to have the blower wheel cleaned and fan motor replaced. I replaced the fan motor, and everything is on and running at this time.
