A.O. Smith Service Done Right in Dana Point

A.O. Smith is one of North America's largest water heater manufacturers, with a wide range of tank and tankless units across multiple price points.

A.O. Smith is one of the largest water heater manufacturers in North America, producing a comprehensive range of residential and commercial tank and tankless water heaters. Their units are sold through both contractor channels and retail stores, making them one of the most commonly installed brands across Dana Point.

Our technicians are experienced with A.O. Smith's full product lineup including their Signature, ProLine, and Voltex series, and carry common parts for same-visit repairs. We also perform annual sediment flush maintenance to extend your unit's life in Dana Point's demanding hard water conditions.

Dana Point A.O. Smith Note: A.O. Smith tank units rated for 8 to 12 years often fail in the 7 to 9 year range in Dana Point due to hard water sediment accelerating corrosion. An annual sediment flush and a water softener are the two most effective steps to reach or exceed the rated lifespan.

Signs Your A.O. Smith Unit Needs Service

1

Hard water sediment at the bottom of the tank — a flush can extend unit life significantly.

Leaking From Tank

May indicate corrosion has penetrated the tank wall — we assess repair vs. replacement.

Thermostat calibration or sediment affecting heating element efficiency.
