Scheduled regular maintenance of our central AC unit on line for a Friday between 8 am and 12 noon. I had to take off work that whole morning to be there. At 1:15 no one had called and no one had come to my home. I called the Customer Service line and they verified that there were no calls made to me but the the technician said he was at my home at 11:20 and I did not answer the door. That was absolutely not the case. At that time I was on the telephone in my study...directly across from the front door...and the landscapers were there -- 5 of them --- doing the front lawn at at time. This is horrendous service. read full review »
