I bought a new 5 ton ac and had it installed on 14 Apr. They didn't leave any filters, said they would bring some out the nest day. They never showed. 4 months later, I got a letter from goettl telling me I had 6 months from date of install to get it inspected and need a certificate on installation to show the inspector. I never got so I called. I was told that a goettl employee would set up an inspection and they would meet the inspector with the needed certificate. No one from goettl ever called. The inspector showed up the next day unexpected and alone. I again called goettl to tell them what happened. They set up an appointment for Aug 23 @ 10AM. About 10 minutes before the scheduled appt, goettl called and said he was going to set up the appointment. I told him it was supposed to be an hour earlier. Several people LIED to me to cover up their lack of professionalism. I won't put up with blatant lying to me. Their slogan of "We do things the right way, not the easy way" is a complete joke. I have used goettl several times, but I will NEVER, EVER use them again. Unless you want unprofessional customer service who is willing to lie about what they said would happen, DON'T even consider using them for anything.
