State reviews skew positive overall. The dominant theme: same product as AO Smith Signature at lower price, with shorter warranty as the tradeoff.
What ProLine owners praise
- Reliability matching AO Smith Signature (same manufacturing)
- Value pricing at Lowe\'s
- LED flash code system makes diagnostics straightforward
- Parts availability through Lowe\'s + AO Smith distribution
- FVIR intake screen — homeowners who clean it annually report fewer 8-flash issues
What ProLine owners complain about
- 6-year warranty (shorter than AO Smith Signature Select 9-year and Premier 12-year)
- Anode rod consumed faster than expected in hard water (universal issue, not State-specific)
- Sediment buildup on units that don\'t get annual flushing
- Power Vent fan noise on some installs (universal power vent issue)
What Premier Hybrid owners praise
- Energy bills drop dramatically vs previous standard electric tank
- IRA tax credit + state/utility rebates can net the install at $500-1,500
- 10-year warranty matches AO Smith Voltex (no warranty downside for the State badge)
- Quiet enough for basement/garage installs (~50 dB)
- Hybrid mode handles peak demand reliably
What Premier Hybrid owners complain about
- Slow recovery in Heat Pump Only mode (8-12 GPH vs 20+ for resistance)
- Condensate drain requires careful install
- Compressor noise objectionable in finished living spaces near bedrooms
- Cold-climate basement installs lose efficiency below 40°F ambient
What Sandblaster commercial owners praise
- Cheaper than AO Smith commercial equivalents
- Standard atmospheric venting works in older commercial buildings
- Reliable for the duty cycle in light commercial applications
Reliability data
State ProLine tank water heaters in residential service typically reach year 8-12 with proper anode rod replacement. Premier Hybrid units installed 2020+ are still in their first decade — early field reports are positive matching Voltex. Sandblaster commercial units in restaurant/salon duty typically reach year 5-8 with annual service.
Who shouldn\'t buy State
- Buyers who want the longer 9-12 year warranty — choose AO Smith Signature Select or Premier instead
- Buyers wanting tankless (State doesn\'t make tankless; AO Smith routes that through Takagi)
- Plumber-channel-only premium buyers — choose Bradford White
Bottom line
State delivers AO Smith manufacturing at value pricing. For warranty-focused buyers, the shorter ProLine warranty is the real tradeoff. For Premier Hybrid heat pump, the 10-year warranty matches Voltex with no penalty — the value play is clearer.
