Rooftop chiller coil service

Challenge
Reduced airflow across a rooftop chiller coil was pushing discharge pressures higher than normal, risking a nuisance trip during peak demand.
Approach
Isolated the unit safely, pressure-washed the coil face, checked fan operation and verified pressures against the equipment nameplate.
Outcome
Coil airflow and running pressures returned to normal range, reducing near-term trip risk.

Approach
Connected gauges to the chiller circuit, checked refrigerant charge and reviewed control setpoints against the building schedule.
Outcome
