What you describe sounds like an AC system with just a little bit too much freon (or air and freon mix). When you charged it did you vacuum the system for at least 10 minutes?

Expert:  Jared D replied 9 months ago.

30 minutes is best, ***** ***** kind of vacuum when doing it at home is tough.

Expert:  Jared D replied 9 months ago.

Also, what kind of pressure are you getting on the high and low side with the engine running?

Customer: replied 9 months ago.

system was evacuated by a machine my mechanic, pressure on high and low sides according to him are high , trying to get some information it seems that his head is spinning, he is trying to guess that there is a restriction in the system somewhere,

Expert:  Jared D replied 9 months ago.

Sorry, your question wouldn't let me lock in to respond last night.

The only place for a restriction in this system would be the expansion valve. Normally, however when the expansion valve malfunctions the system pulls a vacuum on the low side and then about 70 PSI on the high side.

For both sides to be high it just sounds like the system is overcharged. If there was a restriction one side would be higher or lower than normal. If both sides are high then the system just seems to have too much pressure- too much freon causes too much pressure.

I suppose the expansion valve could be stuck wide open, but then it wouldn't really blow very cold at all.
