I went here because of a dashboard error light. Jason told me it was the evac system and the only way to tell was to run a smoke test to see where the leak was coming from. They did the test and found a hose that had been disconnected and tucked under by a previous repair shop very recently. He fixed it and just charged me for the diagnostic test. If he weren't honest he could have easily charged me for some parts and labor and I wouldn't have been the wiser. He also spelled it out on the receipt so I could go back to the other repair shop for reimbursement. Nice to deal with competent, honest people.
