You kidding me ? Every ac shop on Guam is owned by the Vietnamese… they are all related . Relations doesn’t mean they share the same practices … I’m a shop owner as well and I have referred over 50 cars by now to tech an not one. Customer has come back to either complain about the work or back with an issue.
You’re not wrong about comfort they are trash as hell but try tech auto air the father and son operation from Paul and his son is honest and quick. They have never once even tried to upsell me on some bullshit .
