Suction Pressure
Suction Pressure is an important measurement that HVAC technicians use to check how well an air conditioning system is working. It's like taking the blood pressure of an AC unit - it tells you if the system is healthy. This measurement shows how strongly the system is pulling in refrigerant (the cooling fluid). When HVAC technicians mention suction pressure in their experience, it shows they know how to diagnose and fix air conditioning systems. It's sometimes also called "low-side pressure" because it's measured on the low-pressure side of the system.

Example Interview Questions
Senior Level Questions
Q: How do you train junior technicians to properly measure and interpret suction pressure readings?
Expected Answer: A senior technician should explain their teaching process, including safety procedures, proper tool use, and how to interpret readings in different weather conditions. They should mention how they help juniors understand the relationship between suction pressure and system performance.
Q: What troubleshooting steps do you take when encountering abnormal suction pressure readings?
Expected Answer: They should describe a systematic approach to diagnosis, including checking for refrigerant levels, blockages, and component failures. Should mention the importance of considering multiple factors like outdoor temperature and humidity.
Mid Level Questions
Q: What are the normal suction pressure ranges for different types of refrigerants?
Expected Answer: Should demonstrate knowledge of common refrigerants and their typical pressure ranges in different weather conditions, showing understanding of how these readings indicate system health.
Q: How do you document and track suction pressure readings over time?
Expected Answer: Should explain their method for recording readings, tracking system performance over time, and using this information to predict potential issues before they become major problems.
Junior Level Questions
Q: What tools do you use to measure suction pressure?
Expected Answer: Should be able to identify basic pressure gauge sets and digital manifolds, explain how to connect them safely, and describe basic safety precautions.
Q: Why is measuring suction pressure important in AC maintenance?
Expected Answer: Should explain that suction pressure helps determine if the system is working properly and helps identify common problems like low refrigerant or blockages.
