Ac Technician Interview Questions and Answers (Technical)

Here are ten technical questions commonly asked in AC technician interviews along with sample answers:

1. What is the purpose of an air conditioning compressor?

air conditioning compressor

Answer: “The air conditioning compressor is responsible for compressing the refrigerant gas, increasing its pressure and temperature. This high-pressure, high-temperature refrigerant then flows to the condenser where it releases heat, allowing the refrigerant to cool down before entering the evaporator coil.”

2. Can you explain the refrigeration cycle in an air conditioning system?

Answer: “The refrigeration cycle is the process by which an air conditioning system cools and dehumidifies the air. It starts with the compressor, which compresses the refrigerant gas. The compressed gas then moves to the condenser, where it releases heat and becomes a high-pressure liquid. The liquid refrigerant passes through the expansion valve, which reduces its pressure, causing it to evaporate and absorb heat from the surrounding air. The cooled air is then distributed through the system’s ductwork, and the cycle continues.”

3. How do you determine the appropriate refrigerant charge for an air conditioning system?

Answer: “Determining the proper refrigerant charge involves several factors. I refer to the manufacturer’s specifications and guidelines for the specific system being worked on. Additionally, I measure and calculate the superheat and subcooling values to ensure the refrigerant charge aligns with the system’s requirements. By using the correct refrigerant charge, the system operates efficiently and prevents issues such as inadequate cooling or compressor damage.”

4. What is the purpose of an air conditioning evaporator coil?

air conditioning evaporator coil

Answer: “The evaporator coil is responsible for absorbing heat from the air. As the refrigerant evaporates within the coil, it extracts heat energy from the air passing over it, resulting in cool air being circulated into the living or working space. The evaporator coil also plays a role in dehumidifying the air, as moisture condenses on its surface.”

5. How do you troubleshoot an AC system that is blowing warm air?

Answer: “When troubleshooting an AC system blowing warm air, I follow a systematic approach. I check the thermostat settings to ensure it is set to cooling mode and the desired temperature. Then, I inspect the air filter for blockages and clean or replace it if necessary. Next, I verify that the outdoor unit’s fan is functioning properly and that the condenser coils are clean. Additionally, I check refrigerant levels, inspect for refrigerant leaks, and assess the compressor’s operation. By methodically addressing these components, I can identify and resolve the issue causing warm air.”

6. What is the purpose of an air conditioning condenser coil?

Answer: “The condenser coil in an air conditioning system helps dissipate heat from the refrigerant. As the high-pressure refrigerant gas flows through the condenser coil, it releases heat to the surrounding air. This process allows the refrigerant to cool down and convert into a high-pressure liquid before entering the expansion valve.”

7. How do you troubleshoot an AC system that is not turning on?

Answer: “When troubleshooting an AC system that is not turning on, I follow a step-by-step process. First, I check the power supply and ensure that the unit is receiving electricity. I inspect the circuit breaker or fuse box to ensure it hasn’t tripped or blown. If the electrical components are functioning correctly, I examine the thermostat and verify that it is set correctly. Additionally, I check for any loose wiring connections or damaged components that may be preventing the system from turning on.”

8. How do you identify and repair refrigerant leaks in an AC system?

Answer: “To identify refrigerant leaks in an AC system, I use various methods such as visual inspections, electronic leak detectors, or UV dye tests. Once a leak is detected, I determine its location and assess the severity. Repairing the leak involves fixing or replacing the faulty component, such as a damaged coil or tubing, and ensuring proper sealing. After the repair, I evacuate the system, conduct a pressure test, and recharge the refrigerant to the correct levels.”

9. How do you troubleshoot an AC system that is producing unusual noises?

Answer: “When troubleshooting an AC system producing unusual noises, I start by identifying the type of noise and its location. Rattling or vibrating noises could indicate loose components or a faulty fan motor. Hissing sounds might suggest a refrigerant leak. Grinding or squealing noises may point to a worn-out belt or motor bearings. Once I determine the source of the noise, I inspect and repair or replace the relevant component to eliminate the issue.”

10. How do you perform routine maintenance on an air conditioning system?

Answer: “Routine maintenance on an air conditioning system includes tasks such as cleaning or replacing air filters, inspecting and cleaning condenser coils, checking and tightening electrical connections, lubricating moving parts, inspecting and adjusting blower components, and verifying refrigerant levels. Regular maintenance helps ensure optimal system performance, energy efficiency, and longevity.”
