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 condensing unit? (Refrigeration)
- A. Indoor air handler
- B. Outdoor unit containing compressor and condenser coil
- C. A dehumidifier

Answer: B — Outdoor unit containing compressor and condenser coil
The condensing unit is the outdoor portion of a split system containing the compressor, condenser coil, and fan.
-
2. What is latent heat? (Refrigeration)
- A. Hidden heat loss
- B. Heat absorbed or released during a phase change without temperature change
- C. Low-grade heat
- D. Heat from lighting
Answer: B — Heat absorbed or released during a phase change without temperature change
Latent heat is the energy absorbed or released during a phase change (liquid to gas or vice versa) without temperature change.
-
3. What is a ductless mini-split system? (Refrigeration)
- A. A system with damaged ducts
- B. A split system that uses individual air handlers instead of ductwork
- C. A single-room fan
- D. A window unit
Answer: B — A split system that uses individual air handlers instead of ductwork
Mini-splits use individual wall-mounted air handlers connected to an outdoor unit without ductwork.
-
4. What does EER stand for? (Efficiency)
- A. Electrical Energy Rating
- B. Energy Efficiency Ratio
- C. Equipment Evaluation Report
- D. Environmental Efficiency Rate
Answer: B — Energy Efficiency Ratio
EER (Energy Efficiency Ratio) measures cooling efficiency at a specific outdoor temperature (95°F).
-
5. What is a return air grille? (Air Flow)
- A. A grill for cooking
- B. An opening that allows room air to return to the air handler
- C. An exhaust vent
- D. A supply register
Answer: B — An opening that allows room air to return to the air handler
