How much ac refrigerant do you add to your new compressor?

You should not attempt to add refrigerant to your new compressor. Adding the refrigerant to an air conditioner is a task that should be performed by a certified professional. If too much refrigerant is added to the system, it could cause damage to the compressor and reduce the efficiency of the air conditioner. Also, in vehicles if the refrigerant level is wrong, the air conditioning system will not function properly. An incorrect charge can result in poor cooling performance, compressor damage or worse, a fire.
