According to EPA regulations, the removal of which component is classified as a "major repair"?

• A. Evaporator
• B. Compressor
• C. Condenser
• D. Expansion valve

Answer: (B)

The removal of the compressor is classified as a "major repair" under EPA regulations because the compressor is a critical component of a refrigeration system responsible for circulating the refrigerant. Its removal typically involves significant disassembly of the system, and it can have a substantial impact on the system's operational integrity and efficiency.

Major repairs are defined as those that require a significant amount of time or effort and often involve handling refrigerants directly, which requires special attention to safety and compliance with EPA regulations. Because the compressor is integral to the system's function, its removal necessitates stringent adherence to recovery practices and may expose the system to additional risks if not handled correctly.

In contrast, other components such as the evaporator, condenser, and expansion valve may not be classified under the same category because their removal does not typically entail the same level of complexity or require the same regulatory considerations when it comes to refrigerant handling and system integrity.
