Sample HVAC Technician Practice Questions
Six questions from the free hvac technician bank, with the answer and the reasoning behind it.
-
1. What does a reversing valve do? (Refrigeration)
- A. Increases pressure
- B. Reverses refrigerant flow
- C. Filters refrigerant
- D. Measures temperature
Answer: B — Reverses refrigerant flow
A reversing valve changes the direction of refrigerant flow to switch between heating and cooling modes.
-
2. What is the purpose of a crankcase heater? (Refrigeration)
- A. Heat the building
- B. Prevent refrigerant from migrating to compressor oil
- C. Speed up defrost
- D. Heat return air
Answer: B — Prevent refrigerant from migrating to compressor oil
A crankcase heater keeps compressor oil warm to prevent liquid refrigerant from mixing with it during off cycles.
-
3. What does CFM stand for? (Air Flow)
- A. Cubic Feet per Minute
- B. Central Fan Motor
- C. Cooling Factor Measurement
- D. Condenser Flow Meter
Answer: A — Cubic Feet per Minute
CFM stands for Cubic Feet per Minute, measuring the volume of air flow in HVAC systems.
-
4. What is a variable frequency drive (VFD)? (Controls)
- A. A type of thermostat
- B. Controls motor speed by varying frequency
- C. A refrigerant gauge
- D. An air filter
Answer: B — Controls motor speed by varying frequency

-
5. What is a zoning system? (Controls)
- A. A city permit
- B. Controls temperature independently in different areas
- C. A type of ductwork
- D. An outdoor unit
Answer: B — Controls temperature independently in different areas
A zoning system uses dampers and multiple thermostats to independently control temperature in different areas.
-
6. What is a plenum in HVAC? (Air Flow)
- A. A type of refrigerant
- B. An air distribution box connected to supply or return ductwork
- C. A motor type
- D. A thermostat setting
Answer: B — An air distribution box connected to supply or return ductwork
