Mission Critical Terminology Practice Test

Testing, Adjusting, and Balancing focuses on proving that an HVAC system actually delivers the design values it was built to meet. On site, technicians measure real performance—airflow in each duct, static pressures, supply and return temperatures, and room conditions—and compare these against the design specifications. When there are gaps, they adjust components (damper positions, valve settings, fan speeds) and rebalance zones so the system matches the intended performance. This direct measurement and tuning is what ensures the system meets the design criteria and supports environmental goals like proper ventilation, energy efficiency, and consistent indoor conditions. Building commissioning is a broader process that covers planning, verification, documentation, and overall system operation, while the other terms aren’t standard methods for confirming HVAC design-spec conformance.
