Air Conditioning Recharge
It may be necessary to recharge the air conditioning system refrigerant if the system has lost its cooling efficiency. Before any AC system repairs are performed, the system must be free of moisture and contaminates and leaks should already be repaired.
To recharge the AC system, gauges are attached to the AC system to measure pressures in the system, and refrigerant is added as needed.
AC systems should be worked on only by competent, trained personnel.
