When investing in a heat pump water heater, understanding the warranty is crucial. It protects your investment and ensures peace of mind. AO Smith offers some of the best warranties in the market, but what exactly do they cover? How long do they last? And is it worth opting for extended coverage? I dive into these questions to help you make an informed decision.
AO Smith Heater Warranty Details: What’s Covered?
AO Smith provides warranties that cover various components of their heat pump water heaters. Typically, the warranty includes:
Tank warranty: Covers leaks and defects in the water storage tank.
Parts warranty: Covers components like the compressor, fan, and controls.
Labor warranty: Covers the cost of labor for repairs during the warranty period.
The length of coverage varies by model and region but generally ranges from 6 to 12 years for the tank and 1 to 5 years for parts and labor. This tiered approach means you get long-term protection on the most critical part - the tank - while other components have shorter coverage.
AO Smith’s warranty is designed to cover manufacturing defects, not damage caused by improper installation, maintenance neglect, or external factors. So, regular maintenance is essential to keep your warranty valid.

How to Register and Maintain Your AO Smith Warranty
Registering your AO Smith heat pump water heater warranty is straightforward but essential. Most warranties require registration within a specific time frame after purchase, usually 30 to 60 days. You can register online or by mailing the warranty card.
To maintain your warranty:
Schedule regular maintenance checks.
Use authorized service providers for repairs.
Keep all receipts and service records.
Follow the manufacturer’s installation guidelines.
Failing to follow these steps can void your warranty. For example, if you install the unit yourself without professional help, AO Smith may refuse warranty claims related to installation errors.
If you need to make a claim, contact AO Smith customer service promptly. They will guide you through the process and may require proof of purchase and maintenance records.
Is it worth getting a 12 year warranty on a water heater?
A 12 year warranty on a water heater is a significant advantage. Here’s why:
Long-term peace of mind: You won’t worry about costly repairs or replacements for over a decade.
Higher resale value: If you sell your property, a transferable warranty can be a selling point.
Better protection against defects: Manufacturing defects can sometimes appear years after installation.
Cost savings: Avoid unexpected expenses on parts or labor.
However, extended warranties often come with conditions. You must maintain the unit properly and use authorized service providers. Also, some extended warranties may require an additional purchase or registration step.
For heat pump water heaters, which are more complex than traditional models, a 12 year warranty is especially valuable. These units have advanced components like compressors and fans that can be expensive to repair.
In my experience, opting for the longest warranty available is a smart move. It aligns with the typical lifespan of a quality heat pump water heater and protects your investment.
What Does the AO Smith Heat Pump Water Heater Warranty Include?
The ao smith heat pump water heater warranty covers:
Tank: 10 to 12 years against leaks and corrosion.

This warranty covers defects in materials and workmanship. It does not cover damage from:
