AC Replacement: Upon inspection of a client's AC unit, which was struggling to efficiently cool the space and emitting unusual noises, I conducted a comprehensive assessment. My findings indicated a malfunctioning compressor. Considering the age of the system and anticipating potential future issues with other components, I advised the client to consider replacing the entire AC system instead of solely replacing the compressor. This holistic approach ensures long-term reliability and efficiency, avoiding potential sequential breakdowns in the near future.
