I purchased a Trane heating & cooling system (not cheap) in 2006 from Advanced, at time of installation I added on service contract for few years. Eventually I went to a bi-yearly service maintenance format, which worked well for my family's needs. My furnace has a electrical filter which I am unable to maintain, as I am a disabled veteran and unable to utilize a ladder to reach the electrical filter unit. This week I had a scheduled appointment on Monday 12/09/2013 to service the furnace, I waited and waited at my house, no show from the service tech and no call back from Advanced. I phoned the business 1 hour after the scheduled time frame expired and was told because my appointment was set as a diagnostic service/tune up, I was low priority, as there were other people with serious heating problems. I spoke with Alanna (spl), whom I was led to believe was the manager, she apologized for the mis-communication and set up another appointment 9 am-11:00 am for today; Friday 12/13/2013. Again no show by Advanced! I phoned their office @ 11:47 am and spoke with Alanna (spl) she didn't offer any reason for the no-show but stated that a service tech would be at my house in another hour. I had explained to her on Monday that I'm unable to be at my house on Friday afternoon (VA medical appts.). At this point in our conversation, I was very displeased having been a regular customer and now feeling that I'm being shuffled around..and now my heating unit is not fully functional. Needless to say there must other customers with loads of money to spend, since I am now back to square 1; no service, maybe I'll get a appointment next week. Thanks for nothing Advanced, hopefully my family (2 young daughters included) will get use to the chilly temps in our house and my medical condition won't worsen.
