Goettl Air Conditioning & Plumbing review: Tankless water heater

Goettl charged me $21,000 for a tankless water heater install and it works sometimes but never in the morning when I try to take a shower before work. They tried to fix the issue on 4 separate occasions and now they refuse to accept my call. Be aware of their deceptive trade practices, I am an attorney and plan to file a lawsuit to seek treble damages under the deceptive trade practices act, please let me know if you would like to join my lawsuit
