Refrigeration System Maintenance Services With Kuhlman

At Kuhlman, our experienced technicians deliver a range of maintenance services for custom and standard refrigeration systems, including:


Kuhlman offers calibration services to help maintain controls for optimal performance. When refrigeration systems do not have proper calibration, the system can be less energy-efficient. Temperature sensors, gauges, and slide valves also require calibration to deliver the best performance. Improper calibration can result in:

  • Compensating for unknown factors with more conservative settings
  • Misinformation regarding the system and misdiagnosis of system issues
  • Substandard or ineffective performance overall
