AC performance tuneup times two systems. Changed out client supplied filter. Inspect blowers, evaporators and ductwork. York evaporator coil has a small fracture. I did detect a leak inside of that evaporator coil box. I am leaving a quote for what I concluded , the repairs that need to be done for the system to last through the summer. Train system is operating at manufacturer specs at this time. Washed both condenser coils.
