Testing for both voltage and continuity in the AC system is crucial for identifying potential electrical failures and ensuring proper system operation. Voltage testing allows technicians to check if the electrical components of the AC system are receiving the necessary power to function effectively. Without adequate voltage, components such as the compressor, fans, and relays may fail to work, leading to inadequate or no cooling.

Continuity testing, on the other hand, ensures that there are no breaks or shorts in the wiring or connections within the system. If there is a discontinuity in the electrical path, it indicates a failure point that could prevent the AC system from functioning as intended. By conducting these tests, technicians can quickly isolate problems, verify that components are operational, and ensure the AC system operates efficiently without electrical issues affecting performance.

In contrast, checking refrigerant levels pertains to the thermal and pressure aspects of the system. Measuring temperature efficiency focuses on the system's ability to cool, while verifying the physical integrity of components deals with the structural state of parts rather than their electrical functionality. The key focus in this case is on electrical integrity, which makes identifying potential electrical failures and ensuring operation vital.
