Commercial HVAC repair. Noisy operation. I’m going to grease the bearing again while it is running. We may have to order new blower bearings and a shaft and pull the blower assembly and rebuild it. I would do this on a cool day, though. Also administration unit tripped breaker Friday and when we arrived it was off and tripped again I reset breaker and did amp reads on all 3 legs they are running 18-22 amps the main breaker is 60 amps but is warm to the touch, after unit was running for sometime also the unit is on year 3 has so wear and tear on it which will make the breaker warm. I also swept the cottonwood off the police AC unit.
