Responded to a no-cooling request at a Riverside County commercial property. Our HVAC technician found no power going to the unit. Found the breaker in the electrical panel off, not tripped. Was told by the manager on duty that a sign technician had been out working on their light-up signage the day before. Labeled the breaker as RTU #1 to avoid issues like this in the future. Once powered on, system is working well with a 52 degree supply temperature.
