Q&A | Instant Download Pdf
1. Which type of refrigerant is commonly used in residential air
conditioning systems in Georgia?
A. Ammonia
B. R-22
C. R-410A
D. Carbon dioxide
R-410A is the most common modern refrigerant for residential AC
systems due to its efficiency and ozone safety.
2. What is the primary function of a condenser in an air conditioning
system?
A. Absorb heat from indoor air
B. Release heat to the outdoor environment
C. Compress refrigerant
D. Filter the air
The condenser expels heat absorbed by the refrigerant to the
outside environment.
3. Which component of an AC system compresses the refrigerant
gas?
A. Evaporator coil
, B. Compressor
C. Expansion valve
D. Condenser coil
The compressor increases the refrigerant pressure and
temperature, enabling heat transfer.
4. What is the purpose of the evaporator coil?
A. Release heat to the outdoors
B. Compress the refrigerant
C. Absorb heat from indoor air
D. Increase refrigerant pressure
The evaporator coil removes heat from indoor air, cooling the
space.
5. What type of electrical protection device is typically installed on a
residential AC system?
A. GFCI only
B. Circuit breaker
C. Transformer
D. Rectifier
Circuit breakers protect the system from overcurrent and electrical
faults.
6. What does SEER stand for in air conditioning systems?
A. Standard Energy Efficiency Rating
B. Seasonal Energy Efficiency Ratio
C. Specific Energy Efficiency Rating
D. System Energy Emission Ratio
SEER measures the cooling output of an AC system relative to its
energy consumption over a typical season.
, 7. What is the minimum clearance required around an outdoor
condenser unit?
A. 6 inches
B. 12 inches
C. 24 inches
D. 48 inches
Adequate clearance ensures proper airflow and efficient heat
rejection.
8. Which of the following is a common cause of compressor failure?
A. Dirty air filter
B. Low refrigerant levels
C. Electrical overload
D. Improper duct sizing
Electrical overload or improper voltage can damage compressors.
9. In a split AC system, where is the indoor unit typically located?
A. Outside, on the ground
B. Inside the building
C. On the roof only
D. Near the outdoor condenser
The indoor unit contains the evaporator coil and air handler,
circulating cooled air.
10. What is the primary purpose of a TXV (Thermostatic
Expansion Valve)?
A. Compress refrigerant
B. Heat indoor air
C. Regulate refrigerant flow into the evaporator
D. Measure system pressure
