Top 10 Questions for Air Moving Technician Interview

1. What are the key components of an air handling unit (AHU) and what is the function of each component?

• Filter: Captures dust, dirt, and other contaminants from the air.
• Cooling coil: Removes heat from the air using cold water or refrigerant.
• Heating coil: Adds heat to the air using hot water or steam.
• Blower: Circulates the air through the AHU and ductwork.
• Damper: Controls the airflow through the AHU.
