1. What is the primary purpose of air balancing in HVAC
systems?
A. Increase refrigerant pressure
B. Ensure proper airflow distribution
C. Reduce electrical consumption only
D. Replace ductwork
Rationale: Air balancing ensures each space receives the
designed airflow for comfort and efficiency.
Correct Answer: B. Ensure proper airflow distribution
2. Which instrument is commonly used to measure air velocity
in ducts?
A. Manometer
B. Anemometer
C. Psychrometer
D. Tachometer
,Rationale: Anemometers measure air speed directly in ducts
and vents.
Correct Answer: B. Anemometer
3. What does CFM stand for in HVAC systems?
A. Cooling Flow Measurement
B. Cubic Feet per Minute
C. Controlled Fan Mode
D. Current Flow Measurement
Rationale: CFM measures airflow volume in HVAC systems.
Correct Answer: B. Cubic Feet per Minute
4. What is static pressure in a duct system?
A. Air temperature in ducts
B. Resistance to airflow in the system
C. Fan motor speed
D. Moisture level in air
Rationale: Static pressure represents resistance airflow faces in
ducts.
Correct Answer: B. Resistance to airflow in the system
5. Which tool measures static pressure in HVAC systems?
,A. Hygrometer
B. Manometer
C. Thermometer
D. Flow hood
Rationale: A manometer measures pressure differences in
ducts.
Correct Answer: B. Manometer
6. What is the purpose of a balancing damper?
A. Increase refrigerant flow
B. Control airflow in duct branches
C. Measure temperature
D. Clean air filters
Rationale: Dampers regulate airflow distribution in ducts.
Correct Answer: B. Control airflow in duct branches
7. Which airflow condition indicates an unbalanced system?
A. Equal airflow in all zones
B. Excess airflow in one room and low in another
C. Constant temperature everywhere
D. Low humidity only
Rationale: Uneven airflow indicates imbalance.
Correct Answer: B. Excess airflow in one room and low in
another
, 8. What is a flow hood used for?
A. Measuring refrigerant pressure
B. Measuring supply air volume at diffusers
C. Cleaning ducts
D. Heating air
Rationale: Flow hoods measure airflow at outlets.
Correct Answer: B. Measuring supply air volume at diffusers
9. What is the first step in air balancing?
A. Adjust dampers
B. Measure system airflow
C. Replace filters
D. Seal ducts
Rationale: Initial measurement establishes baseline system
performance.
Correct Answer: B. Measure system airflow
10. What does a high static pressure reading usually indicate?
A. Oversized ducts
B. Restricted airflow
C. Low fan speed
D. Clean system
