Air Handler
An Air Handler is a large piece of equipment that manages air flow in buildings' heating and cooling systems. Think of it as the heart of a building's air system - it moves, filters, heats, or cools air before sending it through the building. When someone mentions working with Air Handlers (also called AHUs or Air Handling Units), they're talking about installing, maintaining, or repairing these essential systems that keep buildings comfortable. It's a key part of what HVAC technicians work with, alongside other equipment like furnaces and air conditioners.
Examples in Resumes

Senior Level Questions
Q: How would you handle a large commercial building's Air Handler that's not maintaining proper air pressure?
Expected Answer: A senior technician should explain the systematic approach to troubleshooting: checking fan belts, motor operation, damper positions, ductwork for leaks, and filter conditions. They should also mention the importance of checking building pressurization and control systems.
Q: Describe your experience managing a team during a major Air Handler replacement project.
Expected Answer: Should discuss coordinating with different trades, scheduling around building occupancy, ensuring safety procedures, managing timeline and budget, and minimizing disruption to building operations.
Mid Level Questions
Q: What regular maintenance steps do you perform on Air Handlers?
Expected Answer: Should mention checking belts, lubricating bearings, cleaning or replacing filters, inspecting coils, checking drain pans, testing controls, and verifying proper air flow and temperatures.
Q: How do you diagnose unusual noise coming from an Air Handler?
Expected Answer: Should explain listening for specific types of sounds (squealing, grinding, rattling) and what each might indicate (belt issues, bearing problems, loose components) and the process of inspection and repair.
Junior Level Questions
Q: What are the basic components of an Air Handler?
Expected Answer: Should identify main parts like blower fan, filters, heating/cooling coils, dampers, and drain pan. Should understand basic function of each component.
Q: What safety procedures do you follow when working on Air Handlers?
Expected Answer: Should mention proper lockout/tagout procedures, wearing appropriate PPE (personal protective equipment), ensuring power is off before servicing, and basic electrical safety.
