IR Thermography Test Infrared thermography uses thermal imaging to assess electrical systems for hidden issues such as overheating connections and components. By detecting temperature abnormalities that are not visible to the naked eye, it helps prevent equipment failures, electrical fires, and costly downtime. This non-invasive technique converts heat signatures into visual thermal images, where color […]

Duct Leak Test A duct leak test is a diagnostic procedure used to measure the air tightness of a building’s ductwork. It helps identify and quantify air loss that can reduce system efficiency and affect indoor air quality. During the test, all supply and return registers are temporarily sealed, and a calibrated fan is connected […]

Electrical Live Test Electrical live testing is the process of evaluating an electrical system while it is energized to assess its performance, functionality, and safety. It is typically carried out when shutting down the system is not practical and involves using specialized instruments to measure voltage, current, impedance, and other operating parameters. Live testing helps […]

Electrical Cold Test An electrical cold test is a diagnostic procedure carried out on an electrical system without applying power. Its purpose is to verify correct wiring, check continuity, and measure insulation resistance before the system is energized. This step is essential to prevent equipment damage and ensure personnel safety during initial startup. Why Is […]

What Is Chilled Water Balancing? Chilled water balancing is a systematic procedure used to adjust and regulate water flow rates across the entire chilled water system—from the chiller plant to air handling units (AHUs) and fan coil units (FCUs).The objective is to ensure that each terminal unit receives the precise flow rate required to achieve […]

What is air balancing? Process: A technician uses testing devices to measure the airflow and temperature in different areas of a building. Adjustments: They then make adjustments to the system’s components, such as air diffusers, dampers, and fans, to regulate the air supply. Goal: The objective is to match the actual airflow to the designed airflow to achieve […]

HVAC System Testing and Commissioning The purpose of Testing and Commissioning (T&C) of HVAC systems is to ensure that all components — including equipment, ductwork, piping, and controls — are installed, adjusted, tested, and verified to operate as per the design intent, contract specifications, and manufacturer’s recommendations.The process confirms that the HVAC system performs safely, […]
