Lowe\'s Home Services
If you purchased through Lowe\'s, their Home Services team can handle some warranty questions and dispatch authorized contractors. Often faster initial response than going through AO Smith corporate, though complex issues still escalate to AO Smith.
Bottom line
Have model and serial ready. Support is competent for tank diagnostics. Hybrid issues may need escalation to AO Smith heat pump engineering (24-48 hour response in some cases).
