Static Pressure
Static pressure is an important measurement in heating, ventilation, and air conditioning (HVAC) systems. Think of it like the blood pressure of a building's air system - it tells us how well air is moving through the ducts and vents. When HVAC technicians talk about static pressure, they're referring to the force that helps move air through the building's ductwork. It's similar to water pressure in pipes, but for air instead. Understanding static pressure is crucial because it affects how well heating and cooling systems work, how much energy they use, and how comfortable a building feels.

Example Interview Questions
Senior Level Questions
Q: How would you troubleshoot a complex static pressure issue in a large commercial building?
Expected Answer: A senior technician should discuss systematic approach including measuring pressure at different points, checking for duct restrictions, verifying fan performance, and understanding how the entire system works together. They should mention using diagnostic tools and past experience to identify problems.
Q: How do you train junior technicians on proper static pressure testing?
Expected Answer: Should demonstrate leadership skills by explaining their teaching method, emphasizing safety, proper tool use, and the importance of accurate measurements. Should mention common mistakes to avoid and how to interpret results.
Mid Level Questions
Q: What tools do you use to measure static pressure and how do you ensure accurate readings?
Expected Answer: Should be able to explain use of manometers and other pressure measuring devices, proper placement of test points, and factors that might affect readings. Should understand normal pressure ranges for different systems.
Q: What steps do you take to correct high static pressure in a system?
Expected Answer: Should explain checking for blocked filters, duct restrictions, closed dampers, and other common causes. Should discuss methods to resolve issues and verify improvements.
Junior Level Questions
Q: What is static pressure and why is it important in HVAC systems?
Expected Answer: Should explain basic concept of air pressure in ducts and its impact on system performance. Should understand that proper pressure is needed for efficient operation.
Q: What are normal static pressure readings for a residential system?
Expected Answer: Should know basic pressure ranges and understand when readings indicate a problem. Should be familiar with using basic measuring tools.
