*UPDATE - Please see below. Do not use this facility. They told me that I needed a new air conditioning unit and everything would have to be replaced. They supposedly performed a dye test twice, on two separate occasions and came to the same conclusion each time. They wanted to charge me over 900.00 dollars for the repair. I brought the car home and did a dye test myself. I found that there was a hole in one of the AC lines. I picked up a brand new line from NAPA for under 100 bucks.. changed it out, recharged the AC system and now my AC has worked flawlessly for the past 3 months. I am considering filing a BBB complaint against these scammers. DO NOT BRING YOUR CAR HERE! *UPDATE - So after writing this review, Michael (the store manager) contacted me about my troubles. He was very professional and sorry for what had happened. He reassured me that the technician who performed the second dye test was no longer with Stamps Auto. Michael was not there for the second test and told me that if he had been there, things would have been handled differently. We both agreed that he would compensate me for my ac line, my initial visit charges and also extra for my troubles. I am very pleased by the outcome of this situation and pleasantly surprised by the way this was handled. Michael is very professional and did the right thing for me.
