Maintenance Program

Sutter Data Center

Sacramento, CA

Sutter Health currently utilizes our modified guaranteed maintenance for their data center needs. This program allows for small parts and items under a certain dollar amount to be replaced in a proactive manner to keep the facility up and running. The center has 25 Liebert units and 11 Trane units for its cooling needs. We also have a monitoring agreement in place and receive alarms on the equipment and respond immediately to any need. We have been the maintenance contractor of choice for Sutter Health Data Center since 2000.
