Undetected refrigerant leaks can lead to a range of negative consequences, including reduced system efficiency, increased energy consumption, and system failures. Leaks can also cause compressor damage, leading to costly repairs or even replacement. Furthermore, refrigerant leaks release harmful greenhouse gases into the atmosphere, contributing to environmental harm. In addition, undetected leaks can lead to safety hazards, such as asphyxiation or explosions, in extreme cases.
