Reduce your risk of unexpected downtime and expensive emergency repair costs resulting in Automatic Transfer Switch (ATS) failure with a Holt of California Planned Maintenance program.

At Holt of California, we customize each ATS Inspection and maintenance contract to meet the needs of our customers. Our maintenance services team can schedule a service to take place any day of the week and at any hour.

Enrolling your ATS into our Planned Maintenance program can help to identify problems before a failure occurs. During the initial installation, start-up and commissioning, special attention is given to the integrity of power cables, enclosure mounting and interconnect wires. Over time, these components can deteriorate, vibrate loose or become contaminated by the environment. Without regular maintenance, failure can occur, which can cause extensive damage to the ATS, generator and downstream loads.

Enjoy peace of mind that your system has the best chance of working properly during the next power outage with a maintenance contract from Holt of California. Services performed by our factory-trained technicians are well documented. We even call you to schedule an appointment when you're due for service.

We are an authorized sales, service and warranty dealer for Caterpillar and Zenith ATS switches and additionally service the following ATS brands:

  • Asco
  • Cutler Hammer
  • Onan
  • Russelectric
  • Generac
  • Kohler
