I brought my car in to get A/C converted to r134a from r12 and they claimed to do the service. I was returned a car that did not have fixed A/C so I brought it to the Toyota dealership they proved that RM did not do my service. An A/C conversion consists of changing ALL the o rings to r134a safe ones as well as other things. On my phone call with his worker he told me he did not change all the o rings. In my trunk I found the box with the sticker that is meant to be place on hood stating service was complete. This sticker was sitting in the box with every single o ring still inside, not installed onto vehicle. Do not trust the positive reviews. Mike tells people he will give discount to give a positive review.
