Common HVAC Technician Questions and Their Answers
Electrical Systems and Controls
1. Q: What is the purpose of a contactor in an HVAC system?
A: A contactor acts as a switch that controls the compressor and condenser fan motor, allowing them to turn on and off based on thermostat signals or control logic.
2. Q: How do you troubleshoot a non-starting compressor?
A: Check for power supply issues, inspect overload relays, verify contactor operation, and test the compressor windings for shorts or opens.
Refrigeration and Cooling Systems
1. Q: What are the signs of low refrigerant levels?
A: Reduced cooling capacity, ice build-up on evaporator coils, higher-than-normal pressure readings, and compressor overheating.
2. Q: How do you charge a refrigerant system?
A: Connect gauges to the service ports, evacuate the system if necessary, and add refrigerant gradually while monitoring pressure and temperature to reach manufacturer specifications.
Air Distribution and Ventilation
1. Q: Why is proper airflow important in HVAC systems?
A: Adequate airflow ensures efficient heat transfer, prevents system strain, and maintains indoor air quality.
2. Q: How can you improve airflow in a duct system?
A: Seal leaks, clean or replace filters, reduce duct restrictions, and ensure vents are unobstructed.
Safety and Codes
1. Q: What safety precautions should HVAC technicians follow?
A: Use personal protective equipment, turn off power before servicing electrical components, verify refrigerant containment, and follow OSHA standards.
2. Q: Why is adherence to local codes important?
