What are the typical symptoms of excessive pressure in an air conditioning system?

The typical symptoms of excessive pressure in an air conditioning system are characterized by both high suction pressure and high discharge pressure. This condition indicates that the refrigerant is not circulating properly or that there may be an obstruction in the system.

High suction pressure suggests that the evaporator is not absorbing enough heat, which can happen if there is a refrigerant overcharge or issues with the expansion device. Meanwhile, high discharge pressure indicates that the compressor is working harder than necessary to push the refrigerant through the system, which can lead to overheating and potential damage to the compressor.

Recognizing these high pressures is crucial for technicians because it helps diagnose problems early before they lead to system failures or costly repairs. Understanding that both pressures are elevated provides insight into the overall state of the system and points towards the necessity for service or further investigation into the components involved.
