1. Which license classification allows a conditioned air contractor to work
on systems of unlimited capacity?
A. Class II
B. Restricted Class
C. Limited Class
D. Class I
Answer: D
Rationale: Class I allows installation, service, and repair of
conditioned air systems of unlimited capacity under Georgia law.
2. Which component is primarily responsible for increasing refrigerant
pressure in a vapor-compression system?
A. Evaporator
B. Condenser
C. Compressor
D. Expansion valve
Answer: C
Rationale: The compressor raises the pressure and temperature of
the refrigerant vapor.
,3. What is the primary purpose of a condenser in an HVAC system?
A. Absorb indoor heat
B. Reject heat to the surroundings
C. Meter refrigerant flow
D. Dehumidify indoor air
Answer: B
Rationale: The condenser releases heat absorbed from the indoor
space to the outside environment.
4. Which refrigerant property allows heat transfer during phase change
at constant temperature?
A. Sensible heat
B. Superheat
C. Latent heat
D. Specific heat
Answer: C
Rationale: Latent heat is absorbed or released during a change of
state without temperature change.
5. What instrument is used to measure airflow in duct systems?
A. Manifold gauge
B. Psychrometer
C. Anemometer
D. Micron gauge
Answer: C
Rationale: An anemometer measures air velocity, which is used to
calculate airflow.
6. Which type of heat transfer occurs through direct contact of
molecules? A. Radiation
, B. Conduction
C. Convection
D. Evaporation
Answer: B
Rationale: Conduction is heat transfer through direct molecular
contact.
7. What is the primary function of an expansion valve?
A. Compress refrigerant
B. Condense refrigerant
C. Control refrigerant flow and pressure
D. Store refrigerant
Answer: C
Rationale: Expansion valves meter refrigerant flow and reduce
pressure entering the evaporator.
8. Which system component removes moisture from indoor air?
A. Condenser
B. Compressor
C. Evaporator coil
D. Blower motor
Answer: C
Rationale: Moisture condenses on the cold evaporator coil during
cooling.
9. What electrical device protects motors from overload conditions?
A. Transformer
B. Contactor
C. Overload relay
D. Capacitor
