Which action should you take?

Choose only one option

To check for leaks in the refrigerant system

To ensure that the system operates at the correct pressure range

To verify that the thermostat settings are accurate

To determine whether the compressor is oversized

Question 2: How do you determine the correct size of an HVAC system for a specific building or room?

Which action should you take?

Choose only one option

By choosing the largest available system to ensure high performance

By performing a Manual J load calculation based on the size, insulation, and purpose of the space

By using the same system size for every room size

By estimating based on the building's square footage alone

Question 3: Why is sealing and insulating ductwork essential for HVAC energy efficiency?

Which action should you take?

Choose only one option

It increases airflow, improving system cooling speed

It prevents air leaks, ensuring that conditioned air reaches its destination without energy loss

It reduces the need for air filters, improving system air quality

It increases refrigerant flow, improving cooling capacity

Question 4: What is the main purpose of the air handling unit (AHU) in an HVAC system?

Which action should you take?

Choose only one option

To control refrigerant flow and temperature

To filter outdoor air before it enters the building

To regulate humidity levels in the building

To circulate and condition the air throughout the building

Question 5: What is the purpose of refrigerant recovery equipment certification under EPA regulations?

Which action should you take?

Choose only one option

To ensure that refrigerants are recovered properly without being vented into the atmosphere

To ensure that technicians are paid for refrigerant recovery

To monitor energy consumption during refrigerant recovery

To ensure that only high-efficiency equipment is used

Question 6: What could cause a water leak from the HVAC system?

Which action should you take?

Choose only one option

A broken fan motor that affects condensation flow

Low refrigerant causing excessive moisture condensation

Incorrect thermostat settings causing condensation

A clogged condensate drain or improperly insulated pipes
