What are the most common ways leaks can occur?

• A. Wear and tear
• B. Poor initial construction
• C. Wear and tear, poor initial construction
• D. Improper maintenance

Answer: (C)

Leaks usually come from two common realities: parts wear down with use and flaws from how a component was built or installed. Over time, seals, gaskets, hoses, and joints face pressure, temperature changes, and vibration, which gradually create tiny openings that let refrigerant or fluid escape. At the same time, if something wasn’t constructed or installed correctly, weak welds, improper fittings, or misaligned seals can produce leaks from the start. Together, these two factors—wear and tear and poor initial construction—cover the main ways leaks develop, making the combined option the most accurate choice. While improper maintenance can contribute to leaks, the fundamental causes are aging of parts and initial construction deficiencies.
