Not very happy with my service trip there. I have a 2008 Ford Mustang GT. A/C system is leaking from the schrader valves in the low and high side ports. I took it in to have it fixed. My service advisor Brandon Gafgen was very professional and took my car right in. Then it went down hill from there. After about 15 minutes with the mechanic i get a estimate of $944. dollars to fix it. The mechanic stated that he could not remove the schrader valve from the low side. So, they want to charge me for a whole new a/c hose. So, i tell them not to fix it. It was way too much. So,after waiting another 45 minutes they finally bring my car around. Oh,and charge me $100.00 for about 15 minutes of looking at it and not touching it? So,i get home and check the low side schrader valve with my tool and it comes right out with very little effort. Go figure. I ordered a service kit for $15 dollars to fix it myself. Not $944 dollars? It's just a shame i wasted $100. dollars for nothing. Oh,and now i definetly won't be getting my trans flushed there. So,there's $240. dollars they lost. I just don't trust someone that doesn't even try to fix something simple but want to charge me a ridiculous amount of money to do way more then it needed. Only good point was Brandon Gafgen,thank you sir for trying to take care of the customer.
