Certified Detention HVAC Specialist (CDHS) Detention facilities demand HVAC systems that balance security protocols with climate control?a hybrid skillset most general technicians never encounter. The CDHS separates specialists who grasp confined-space airflow management, restricted-access equipment maintenance, and compliance with correctional building codes from those trained only in commercial or residential settings. This exam’s focus on high-security ventilation challenges and emergency system redundancy reflects real detention-center complexity.
