The system will have to be inspected, using pressure gauges on the high and low side, and other tools, in order to determine the exact cause. The relevant service to request is YourMechanic’s a/c system inspection/diagnostic. To give you an indication of possibilities, though, you would have these two, at least: 1) the relief valve is defective; and/or 2) the system pressure is indeed too high due to overcharging, trapped air in the system, blockages or a compressor/compressor controls malfunction. When the mechanic applies pressure gauges that should give him a good initial indication of what is going on. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
