Static Pressure
Static Pressure is a basic but important measurement in heating, cooling, and ventilation systems. Think of it like blood pressure in the human body, but for air in ductwork. It helps HVAC technicians understand how well air is flowing through a building's air conditioning and heating system. When someone mentions static pressure in their resume, they're showing they know how to check if an HVAC system is working efficiently. It's similar to checking water pressure in plumbing, but for air instead. This measurement helps technicians figure out if there are any blockages, if the ducts are too small, or if the system needs cleaning or adjustment.

Example Interview Questions
Senior Level Questions
Q: How would you diagnose and solve complex static pressure issues in a large commercial building?
Expected Answer: A senior technician should explain the systematic approach: checking measurements at different points, understanding the building's layout, considering peak usage times, and developing a comprehensive solution plan.
Q: How do you train junior technicians on proper static pressure testing?
Expected Answer: Should discuss teaching proper measurement techniques, explaining the importance of accurate readings, demonstrating common problem scenarios, and emphasizing safety procedures.
Mid Level Questions
Q: What are the typical causes of high static pressure in an HVAC system?
Expected Answer: Should mention dirty filters, blocked vents, undersized ductwork, too many bends in ductwork, and closed dampers as common causes.
Q: How do you measure static pressure correctly?
Expected Answer: Should explain using a manometer, identifying correct measurement points, and the importance of taking multiple readings.
Junior Level Questions
Q: What is static pressure and why is it important?
Expected Answer: Should explain that it's the pressure inside ductwork that affects air flow, and how it helps determine if a system is working properly.
Q: What are normal static pressure readings for a residential system?
Expected Answer: Should know that typical readings are between 0.5 and 1.0 inches of water column for most residential systems.
