FAQ
Frequently Asked Questions — PM in Chino
How quickly can you respond to Chino facilities?
Our shop is in Santa Fe Springs — San Bernardino County is part of our core territory. For PM contract clients, we respond same day or next day for emergency issues. Scheduled visits are set up in advance on your production calendar.
What types of equipment do you maintain in Chino?
In Chino, we commonly maintain: refrigeration compressors, pasteurization equipment, conveyor lines, pumps, HVAC. If you have equipment outside that scope, tell us what you're running and we'll let you know upfront if it fits our program.
How often do you recommend PM visits for dairy operations?
It depends on equipment age, criticality, and run hours. For most dairy facilities, we start with quarterly visits and adjust based on what we find. High-cycle equipment often warrants monthly checks. We'll make a specific recommendation after a site walkthrough.
Do we need to stop production for a PM visit?
Rarely. We schedule around your shifts and work on equipment during natural downtime windows. When we need a brief shutdown for specific tasks, we coordinate that in advance — no surprises.
What's included in a PM visit report?
Every visit produces a written report: what was inspected, what was found, measurements logged, parts replaced, and anything flagged for follow-up with our recommendation. The report is yours to keep — it becomes your maintenance history.
Do you handle emergency calls between PM visits?
Yes. PM contract clients get priority scheduling for emergency calls. We cover Chino and all of San Bernardino County and can typically respond same day or next day.
