The AO Smith product is of good quality initially. However, there are concerns regarding the after-sales service, particularly with the AMC program. As a Customers I have experienced challenges with the technical expertise of service engineers and the responsiveness of the support teams. When issues are raised, the responses often involve referrals to dealers or regional teams, but resolutions is not there. While the companys website emphasizes prioritizing customer satisfaction but customer support is worst. Based on my experiences, I recommend due to poor service aspect not to go with purchasing AO Smith products.
