Well, it just keeps getting worse with this A/C shop. I did alittle research on the so called R12 that they put in my truck. While I was at the shop I watch them fill the truck with what I thought was a name brand type of R12 called Freeze-12. After doing alittle research I found out that Freeze-12 is a less effiecent alternitive for R12. It is half the cost of R12 and lighter. Which means that it take 10% less to fill a system than R12. The really screwed up thing was that this shop charged me for R12 freon at 40 bucks a pound. I called them on this and they did sayed that they had made a mistake. They now what to take it out and replace it with R12. My problem is whether I should trust them or not. I really dont want to take it back but I feel I dont have much of a choose. This is one of the reason I like to work on my own truck. I know what I am doing to it and I know if it is done right with good parts. I am so glad that I sat out in the shop bay watching them work on the truck or I would have had no idea what they were putting in my truck. I cant even imagine how many people before me got hosed on this kind of wrip off. Makes me sick to even think about it. I would have to say that one of the hardest things to find out there is a good tech that is honest, fair, and trust worthy. Thats all for now. Hope this doesnt happen to any of you..... By the way for anyone in AZ. Dont go to Wright Brothers Automotive and Air on Bell and 59th AVE. You have been warned.
