I brought AutoTech a VW Jetta with a terribly under-performing a.c. system. Allen diagnosed the problem, fixed it, and had it blowing cold air again in just a couple of days. It wasn't a cheap fix, but I didn't expect it to be, and I am confident that the job was done right. The shop is very good about communicating the facts and the options, and then following through on timing as promised. Plus, the people are just fun to be around. I'm completely satisfied, and am comfortable recommending AutoTech to others.
