Trust me, that old review is bad. A guy named Kelly does not work here, been coming here a year, the guy's name is Mike. He is respectful (unlike those asses at the AC place in Round Rock), works his butt off to get you in/out & generally seems like a guy I would hang out with. I got my unit installed in another state & Guardian services multiple states but there computer management system needs work. I always have a hard time when traveling but Mike has always went out of his way to find my info & take care of my business, stick with this guy when in ATX! read more
