• Verify temp and humidity levels as well as proper airflow (electronic monitoring/logging/alerting is a plus here) in multiple spots in the room, not just at the thermostat
  • Have filters changed on a schedule
  • Have an a/c tech perform scheduled maintenance per OEM recommendations
  • make sure your cold/hot aisles are still designed properly as equipment comes and goes
  • keep a log of maintenance along with any issues/notes for future reference
