A/C stopped working on May 21 2011. They sent 5 different (so called techs) to work on it. They made a total of 6 trips to my house and never got it fixed. The last trip was June 23 2011. I ended up calling a different company to fix it. They were nasty on the phone ( I had to call them at lease 25 times to get them to come out. ) AHS did nothing to assist. I canceled that AHS contract, because it is no good.
