Found system fan on and operating normally checked system capacitors, electrical draws, and cycled system to check start up, operation, and shutdown of fan motor. Noted a loss of refrigerant since last visit in May - system has lost about 20-30 psi r410a - system is still operating within manufacturers' specifications but system is still leaking refrigerant and will lose more capacity over time. Recommended tenant to watch system for awhile and explained how fan motor and system operation works and what to do and look for if motor were to prematurely fail again. Still recommend replacement of system evaporator coil.
