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

• A. Replacing a condenser coil
• B. Replacing a light bulb
• C. Replacing a pre-filter
• D. Cleaning the condenser fins

Answer: (A)

Under EPA regulations, a major repair is defined as replacing a major component of the refrigerant circuit or performing work that significantly affects system performance. Replacing a condenser coil fits this because the condenser is a major component of the refrigerant loop responsible for rejecting heat; swapping it out changes how the system operates and typically requires proper refrigerant handling and verification of charge. The other options are routine maintenance or non-refrigerant tasks: replacing a light bulb, replacing a pre-filter, or cleaning the condenser fins do not involve changing refrigerant-circuit components or significantly altering performance. Therefore, replacing the condenser coil is the major repair.
