I have used American Home Shield (AHS) for 20+ years. They are a reputable company. I can't say I have always been thrilled with their policies, but they are, on balance, a fair and respectable enterprise. I don't know why they would call someone at strange hours or anything else weird. I would and do recommend them to my friends regularly.
I have had AHS on 2 different homes, 1 in LA and one in TX. They have treated me fairly and been reputable. Replaced an A/C cost to me was $800, actual cost would have been $3500 for the unit we needed. Saved a bundle and had no hassles. The only thing is you must choose a company contracted through them, but even that isn't hard as they offer a number of local choices to do various work.
Call from 901 266 7600 on Sunday morning 11AM Aug 23, 2009. I use to live in New Jersey, that 901 is a Jersey south area code. I don't even live in that state. Live message with no information, did not take call, they just left message.
Caller ID listed as Sevice Master C, I'm on a don't call list, really tired of these market people waking me up, I work nights.
