Repair, Maintenance & Calibration Services

As specialists in the maintenance, repair, and calibration of environmental chambers, at H&H Environmental Systems we offer a comprehensive lineup of technical support services. We service several types of Environmental Simulation Equipment; temperature, humidity, altitude, shock, HALT/HASS and walk-in chambers. With our dedicated service philosophy, we ensure our customer’s environmental test chambers perform with the highest degree of accuracy and reliability.

We support industries including aerospace, HVAC, military, packaging, cryogenics, consumer goods, semiconductors, robotics, medical devices, and much more. Along with providing repair, retrofit, and upgrade services on an as-needed or emergency basis, we implement our RBF (“Repair Before Failure”) program that integrates real-time monitoring with preventive maintenance to obtain critical operational data of chamber performance. RBF is a Proven Proactive Preventative Maintenance and Repair program that reduces unscheduled downtime, addresses customer’s critical processes and allows repairs to be scheduled around Production and Engineering timetables.

By implementing RBF programs to keep environmental chambers performing reliably and operating efficiently, we help customers reduce the risk of a major breakdown while extending the service lifecycle of their assets.
