What can air entering a refrigerant system lead to?

Condenser blockage
Thermostat malfunction
Compressor failure
Evaporator coil freezing

The correct answer is: Compressor failure

Air entering a refrigerant system can lead to compressor failure. This is because air contains moisture and other contaminants that can cause corrosion and damage to the compressor. In addition, air can also decrease the efficiency of the compressor, leading to overheating and potential failure. Options A, B, and D may also be potential issues caused by air entering a refrigerant system, but they do not specifically address the issue of compressor failure.
