I installed a new condensing unit and put freon in the unit, I am getting the same pressure on the high and low sides of the gauges. This leads me to believe that there is a compressor problem or that I put too much gas in it. I am reading 150 psi on the high side and the gauge is pinned on the low side. Any ideas on what to do?

Please call a professional. I doupt if the compressor is bad but you may have many other problems since you did not pull a vac on the unit and line set etc. I would also like to mention there is a $20,000.00 fine for the venting of refrigerant. Do you have a reclaim machine and use it like you should? Do you have a certification to do this ?
