Preview Questions HVAC Technician | Role Specific Skill

Question 1: What should be done if an HVAC system installation is not producing the expected performance?

Which action should you take?

Choose only one option

Increase system capacity to make up for the underperformance

Ignore the issue and continue operating the system

Replace the thermostat without further troubleshooting

Perform a system check to verify proper installation, refrigerant charge, and airflow

Question 2: What is the role of an HVAC technician in meeting the energy efficiency requirements of the Energy Independence and Security Act (EISA)?

Which action should you take?

Choose only one option

Technicians are responsible for selecting energy-efficient HVAC equipment

Technicians should focus only on controlling indoor air quality, not energy use

Technicians must only check for refrigerant leaks during installation

Technicians must ensure that HVAC systems are installed according to energy-saving guidelines and maintain their efficiency

Question 3: How do air-source heat pumps contribute to energy efficiency?

Which action should you take?

Choose only one option

They increase heating efficiency but have no effect on cooling

They only operate efficiently in moderate climates and require additional heating during the winter

They use electricity to produce both heating and cooling without any energy savings

They provide both heating and cooling, using less energy than traditional systems by transferring heat

Question 4: What should be done if an HVAC system has insufficient airflow during maintenance?

Which action should you take?

Choose only one option

Check for refrigerant leaks

Adjust the fan speed

Inspect and clean the evaporator coil

Clean the ducts and replace filters

Question 5: Which of the following is the proper procedure when conducting routine maintenance on an air handler unit (AHU)?

Which action should you take?

Choose only one option

Replacing the thermostat without inspecting other components

Only checking the refrigerant levels

Ignoring external components like fans or motors

Cleaning or replacing filters, checking coils, and inspecting fan and motor components

Question 6: What should be done if an HVAC system is installed but not providing adequate cooling?

Which action should you take?

Choose only one option

Check the refrigerant charge, the airflow, and the thermostat calibration

Increase the refrigerant charge until cooling improves

Reduce the fan speed to save energy

Check the compressor only and assume the issue is mechanical
