What happens to the pressure when the condenser coil becomes dirty?

In the case of a dirty condenser coil, the reduced heat transfer results in higher than normal head pressure and discharge temperatures. This condition causes the compressor to work harder to pump against the higher pressures. The end result is the compressor motor overheats and wears out prematurely.

What happens if condenser is clogged?

With a dirty or blocked condenser, even the subcooled liquid temperature coming out of the condenser will be at a higher temperature. This means that the liquid temperature out of the condenser will be further from the evaporating temperature.
