How Long Is the A.O. Smith Water Heater Warranty?
It depends on the model line. A.O. Smith residential tank water heaters carry manufacturer warranties from about 6 years on entry models up to 12 years on premium models like the ProLine series, and the length is printed on the rating label on the side of the tank. In most cases the manufacturer warranty covers the tank and parts, not the labor to replace them, which is why the installer’s labor warranty matters. Our labor warranty depends on the system and is written on your quote.

How to Check Your A.O. Smith Warranty With the Serial Number
- Find the rating label on the side of the tank. It lists the model number and the serial number.
- Read the manufacture date. On A.O. Smith water heaters, the first four digits of the serial number are the year and week the tank was built. A serial number starting with 1924 was built in 2019, week 24.
- Look it up. A.O. Smith’s website has a warranty lookup where you enter the serial number to see the coverage on your unit.
- Keep proof of the install date. Without it, coverage is usually counted from the manufacture date, which can cost you months of warranty.
What Voids an A.O. Smith Water Heater Warranty?
These are the most common reasons warranty claims get denied:
- An installation that does not meet code, or a missing or improperly piped T&P relief valve
- Damage from sediment or scale buildup, which is why a yearly flush matters in Tampa hard water
- Running the tank above its rated pressure, often in homes with high city pressure and no expansion tank
- Damage from flooding, freezing, fire, or a tank that was moved after it was installed
- No proof of when the tank was installed
A yearly flush keeps sediment from becoming the reason a claim is denied. Our $89 water heater flush includes a FREE whole-house plumbing inspection.
