Sample HVAC Technician Practice Questions
Six questions from the free hvac technician bank, with the answer and the reasoning behind it.
-
1. What is a split system? (Refrigeration)
- A. A broken system
- B. Indoor and outdoor units connected by refrigerant lines
- C. Two separate AC units
- D. A heating-only system
Answer: B — Indoor and outdoor units connected by refrigerant lines
A split system has an indoor unit (evaporator) and outdoor unit (condenser/compressor) connected by refrigerant lines.
-
2. What is the function of a defrost cycle? (Refrigeration)
- A. Cool the system faster
- B. Remove ice from outdoor coil in heat pump mode
- C. Increase refrigerant flow
- D. Clean the filter
Answer: B — Remove ice from outdoor coil in heat pump mode
The defrost cycle melts ice that builds up on the outdoor coil when a heat pump operates in heating mode.
-
3. What is a Manual J calculation? (Efficiency)
- A. A repair manual
- B. A heating/cooling load calculation for sizing equipment
- C. A refrigerant chart
- D. A duct sizing method
Answer: B — A heating/cooling load calculation for sizing equipment
Manual J is the industry standard for calculating residential heating and cooling loads to properly size HVAC equipment.
-
4. What is short cycling in HVAC? (Troubleshooting)
- A. Using short ducts
- B. System turning on and off too frequently
- C. Low refrigerant
- D. Quick installation
Answer: B — System turning on and off too frequently
Short cycling is when the system turns on and off too frequently, reducing efficiency and increasing wear.
-
