Contractor showed up on June 16, 2021. He was not trustworthy, said some very "shady" things about needing to drain our coolant and add different coolant. We told him we would go with his other diagnosis and wait on that recommendation. We have been contacting AHS since that date. We have asked for another contractor for a second opinion. We have been told they needed to speak with the contractors company, etc.. We have been told a supervisor or manager will give us a return call at least twice now, We have spent over 6 hours on the phone either trying to get to someone or on hold. I am now on again, and am now being told they can not even get someone in the escalation team on the phone. It is 112 degrees in AZ and we do not have AC! WE have been customers of AHS for over 20 years. This is absolutely unacceptable!
