← TechnologyWhich problem results when an air conditioning system refrigerant leak causes substantial pressure reduction?
A)Icing of the evaporator coil✓
B)Compressor motor overheating
C)Reduced cooling efficiency only
D)Increased head pressure throughout system
💡 Explanation
Evaporator icing occurs due to the pressure drop from refrigerant loss decreasing evaporating temperature below 0°C; therefore, moisture freezes on the coil because ice formation, rather than efficient heat transfer, is prioritized at very cold temperatures.
