Preview Questions HVAC Technician | Role Specific Skill

Question 1: Under the Energy Policy Act (EPAct), what is the main goal for HVAC systems in commercial buildings?

Which action should you take?

Choose only one option

To focus only on heating systems and ignore cooling requirements

To promote the use of gas-based HVAC systems over electric systems

To limit the use of HVAC systems to only one per building floor

To reduce energy consumption by improving HVAC system efficiency and ensuring proper maintenance

Question 2: How do variable refrigerant flow (VRF) systems differ from traditional HVAC systems?

Which action should you take?

Choose only one option

VRF systems are not as efficient as traditional systems

VRF systems only provide heating, not cooling

VRF systems allow for independent control of multiple zones, improving efficiency

VRF systems use a single compressor for all zones

Question 3: What does the Low-Emission Refrigerant Management Plan (LERMP) require for HVAC systems?

Which action should you take?

Choose only one option

The use of refrigerants with lower global warming potential (GWP) and their proper handling

An increase in the number of refrigerant types used in HVAC systems

The mandatory use of fluorinated gases in all HVAC systems

The complete phase-out of refrigerants in commercial buildings

Question 4: How should an HVAC technician ensure optimal performance of a cooling system during the operation?

Which action should you take?

Choose only one option

Regularly clean and inspect the condenser coils and evaporator coils

Increase the refrigerant charge regardless of system performance

Only replace the air filter every six months

Ignore the airflow and focus only on refrigerant levels

Question 5: What is the key to ensuring the longevity of an HVAC system after installation?

Which action should you take?

Choose only one option

Using the system intermittently to save energy consumption

Running the system at maximum capacity at all times

Regular maintenance, proper sizing, and appropriate system settings

Ignoring routine service checks as long as the system works

Question 6: What is the primary function of the evaporator coil in an HVAC system?

Which action should you take?

Choose only one option

To filter debris from the air passing through the system

To control the flow of air through the ductwork system

To absorb heat from the air inside the building and transfer it to the refrigerant

To release heat to the environment outside the building
