Sample Air Conditioning Repair Practice Questions
Try these questions from our free Air Conditioning Repair practice tests. The correct answer and an explanation follow each question.
What does the Sensible Heat Ratio (SHR) indicate about an air conditioning system?
- A. The ratio of refrigerant charge to system capacity
- B. The proportion of total cooling capacity devoted to sensible versus latent heat removal
- C. The efficiency rating of the compressor
- D. The ratio of supply air to return air volume
Answer: B. The proportion of total cooling capacity devoted to sensible versus latent heat removal
SHR is the ratio of sensible cooling (temperature reduction) to total cooling capacity, indicating how much of the system's capacity is used for temperature versus humidity removal.
A technician installs a new 2-ton split system and finds the existing ductwork was designed for a 1.5-ton system. What is the most likely result?
- A. Improved comfort due to higher airflow
- B. Higher static pressure, reduced airflow, poor efficiency and comfort
- C. Reduced refrigerant charge requirement
- D. Faster system response time
Answer: B. Higher static pressure, reduced airflow, poor efficiency and comfort
Undersized ductwork increases external static pressure, restricts airflow, reduces system efficiency, and can cause the evaporator coil to freeze.
When brazing copper refrigerant lines, nitrogen should be flowing through the lines at what approximate pressure?
- A. 0 psig (off)
- B. 2–5 psig
- C. 15–20 psig
- D. 50 psig
Answer: B. 2–5 psig
A low nitrogen purge of 2–5 psig displaces oxygen inside the tubing to prevent copper oxide scale formation without blowing out the brazing alloy.
An HVAC technician measures 0V AC between the R and C terminals at the air handler control board with the disconnect closed. What does this indicate?
- A. The thermostat is in standby mode
- B. The 24V transformer has failed or is not receiving primary voltage
- C. The contactor coil is open
- D. The low-pressure switch has opened the circuit
Answer: B. The 24V transformer has failed or is not receiving primary voltage
No voltage between R and C with power applied means the 24V transformer is not producing output, either due to a failed transformer or no primary voltage reaching it.
