They rebuilt my air conditioning system in my 93 Corvette using parts I acquired, new condenser and HP switch and the accumulator that they provided. It works well, although they estimated 5 hours labor, but it took them two days to get it done, hence the four star rating. It seems that they take tow-ins, with out-of-town people standing around waiting for their car, so mine just sat at times. The Chevy dealer couldn't do this job because my car has the old type refrigerant, which they could not provide, but Paso Robles Auto can. Good job overall by Greg, but don't be in a hurry. This is my second time to use these guys - the first was when they did the smog test on the Corvette - it also took a lot longer than they estimated.
