Under EPA regulations, which action would be considered a major repair?

Explanation:
Under EPA regulations, a major repair is defined by work that replaces major components of the sealed refrigerant circuit. Replacing the condenser, compressor, auxiliary heat exchanger, or evaporator involves the key parts that contain and route the refrigerant, directly affecting the system’s operation and integrity. Because these components are part of the sealed loop and require proper refrigerant handling, such work is classified as a major repair. Replacing a fan motor, insulation, or a thermostat, on the other hand, does not involve the sealed refrigerant circuit. These tasks affect non-refrigerant parts or exterior performance and are considered minor repairs or routine maintenance.
