1 review of Ao Smith Water Heaters and Motors "Horrible service and they do not back up their water heater warranty. Stay away from them. Purchased a new water heater in 2015 with a 10 year warranty. Broke in 2019. They did not honor their warranty in the end of fall start of winter. Lame company that can't be trusted."
