Before replacing the compressor I'd replace the expansion valve.

Btw if you do in fact need a compressor I have a brand new Denso 10pa15c in box I'll sell to you less than anywhere online...it's been sitting in my garage after I thought mine was bad and I need it gone now.

Do yourself a favor and go to harbor freight and buy the ac gauge kit it's 50 bucks then you can do all this yourself. 150psi is too low to cool. You'll need closer to 200 before you will feel anything.
