I would give them 0 stars if it was available. They are the worst. On my 1st appointment since I did not know what time they were coming, I went to work. As soon as I stepped into the front door at 8:30 am, the tech called. Had to turn around and go right back home. Why would they not know I was scheduled that early in the morning. Doesn't make sense to me.Note: THEY DO NOT GIVE YOU APPOINTMENT TIMES. YOU MUST MAKE YOURSELF AVAILABLE FROM 8-5 AS THOUGH YOU WORK FOR THEM. I am with AHS and had to call them back out with the same problem after 2 weeks. First it was freon, now I am told I need a coil. Was called and told by a rep that the tech would return 2 days later. Called them about 11:00 am since I had not heard from them to find out if they could estimate what time someone would come today since we are going into the long holiday weekend. I was told by Kenny that I was a liar and no one from US Air called me and rescheduled. I guess it was my imagination of phantom phone call from them by a phantom lady. VERY NASTY GUY WHO CARES NOTHING ABOUT THE CUSTOMER. Did not apologize one time. I will hope that they finish the job on Monday, but will put them on the refuse list at AHS. Only hope now that the job is done correctly. This company really SUCKS.
