Question 1: What is the effect of an undersized air handler in an HVAC system?

Which action should you take?

Choose only one option

It will increase the overall system efficiency

It will struggle to provide adequate airflow, resulting in poor system performance

It will help to reduce the need for air filtration

It will reduce energy consumption

Question 2: How can the installation of a smart thermostat improve energy efficiency in an HVAC system?

Which action should you take?

Choose only one option

By automatically scheduling maintenance tasks

By increasing the airflow to distribute air more effectively

By allowing precise control of the temperature, reducing heating and cooling when not needed

By using more refrigerant to reduce system load

Question 3: How does an air handler unit (AHU) contribute to the heating or cooling process in an HVAC system?

Which action should you take?

Choose only one option

It circulates conditioned air throughout the building by using fans

It stores excess refrigerant for later use

It filters the air to remove contaminants before conditioning

It compresses refrigerant to increase cooling power

Question 4: How can an HVAC technician troubleshoot inconsistent airflow in different rooms of a building?

Which action should you take?

Choose only one option

Increase refrigerant pressure

Replace the air handler

Check for ductwork blockages, leaks, or imbalance in airflow

Adjust the thermostat

Question 5: What is the primary purpose of a pressure switch in an HVAC system?

Which action should you take?

Choose only one option

To control the temperature settings in the evaporator coil

To monitor airflow and adjust the fan speed accordingly

To regulate the thermostat settings based on outdoor temperature

To monitor the refrigerant pressure and shut down the system if the pressure is too high or low

Question 6: How does the condenser coil contribute to the HVAC cooling cycle?

Which action should you take?

Choose only one option

It prevents refrigerant from escaping through leaks

It releases the heat absorbed by the refrigerant, allowing it to cool and condense

It filters the air to ensure better air quality

It circulates air through the system to regulate temperature
