American Home Shield [AHS] review: AC unit repair

I recently submitted a claim to American Home Shield for an AC unit that was not turning on. Two service technicians inspected the unit, the first discovery was that the unit would need to be replaced due to the age, Freon and evaporator coils. American Home Shield sent a second technician to my home and his discovery was that my portion of the repair would exceed over three thousand dollars and according to him the repair would NOT resolve the problem. He also stated that I would be without AC again before the summer was over since this was only a temporary fix. He did include the same diagnosis of Freon and evaporator coil repair. I live in Texas where it can get in the 110's temps and have been without AC for a while now! Due to the AC needing replaced, my electricity bill exceeds $600 per month! AHS does not honor its warranty nor does customer service do anything besides read a script and give you the run around.
