That s why I question the dealers. Gauges are only a diagnostic tool. Without looking up the spec I'm guessing the system holds 2 to 3 lbs. Did they evacuate the system and measure? I'm guessing not. The dealer that said it was high probably only saw a high reading and assumed there was too much. Thats bad because high psi can be caused by a bad expansion valve. Connecting to both high and low sides and making sure the psi is equal would be my first step. Then start the engine,observe the readings. Now shut it all off. You should see the pressures begin to equalize.If not the expansion valve may be bad or blocked. This leads me back to say, make sure the dealer you have is HVAC certified. :cold:
