Timeline of Events: A.O. Smith Warranty Dispute Update -A.O. Smith contacted me And they are going to horror the warranty transfer that the representative said because I had the confirmation number he gave me. They said it’s not their policy to transfer warranties, but they would honor what the representative said even though it was the wrong information. I am a happy camper. Not out $ and a defective unit. Moved to 1 star to 4 star! January 7, 2026 (10:00 AM): I contacted A.O. Smith customer service to inquire whether moving a gas water heater from one property to another would void the warranty. The representative explicitly stated the warranty would remain in effect. She collected my personal information—including my name, address, email, and phone number—to process a formal "site transfer" in their database and provided me with a reference number. Based entirely on this corporate authorization, I invested significant funds into vehicle delivery and professional plumber installation at the new property. July 2026 (7 Months Later): The water heater required service, and I called to file a warranty claim. The initial customer service representative located my updated account information and address in their system. However, I was then informed that the warranty was non-transferable and the claim was denied. When I escalated the call to a manager, the manager claimed they had no record of my January 7th phone call, asserting that "everything is recorded." This statement directly contradicts the fact that the previous representative had just successfully located my transfer information in their database. I would never have incurred the heavy costs of relocation and installation if A.O. Smith's representative had not explicitly authorized the transfer and updated my account.

Wish I could give them 0 stars. Poor warranty and a refusal to try and work with the customer. Their tanks barely last and you will definitely need to replace it.

Bought a hybrid water heater in a new home build within the last 3 years. Water heater has a 10 year warranty. AO Smith immediately agreed that the heater is defective and gave an authorization for Lowes to replace it but Lowes doesn't carry it anymore. I am now stuck between 2 companies who don't care that there is a warranty. I was offered a refund at approx 22% less than what I paid which isn't appropriate or fair. Now, neither company will respond to any communication and I am stuck with a non-functioning water heater with 7 years of warranty left.

I purchased two A. O. Smith water heaters five years ago during a home renovation. Both were installed by a licensed plumber. In May, the first unit catastrophically failed, spraying water throughout my basement. My plumber said he had never seen a water heater fail this way—the back of the tank had actually bulged outward and was spraying water. Even the A. O. Smith customer service representative commented that they had never seen a failure like it. Just one month later, the second water heater also failed, leaking from the bottom overnight and resulting in another costly replacement. While both units were replaced under warranty, A. O. Smith would not cover any installation costs or the significant water bills caused by these failures. I've spent over $2,500 on installation alone. I've also spent hours on the phone trying to speak with a manager, only to receive conflicting information from different representatives and repeated promises of callbacks that never happened. Having two water heaters fail within a month of each other after only five years strongly suggests I received defective units. I'm simply asking A. O. Smith to help with the installation costs caused by these failures. To add to my frustration, I was also told the replacement units do not receive a new warranty period—they only continue the original warranty from the five-year mark. I hope someone from A. O. Smith's customer relations team will finally reach out to resolve this fairly.

I wish I had read the reviews before I bought this thing. I had a plumber install my new A.O. water heater 3 months ago and I had a slight smell to the water. It didn't come from the heater. It was coming from my well. I was told to get an electric anode tube. So, I got one and tried to get the one out of the heater. It won't come out. I tried with a wrench then, went and got an impact wrench with 130 pounds of pressure. It wouldn't move. I called smith and they told me,, Nothing they can do about that. That's not covered under the warranty. So, I'm stuck with this piece of sxxt.. It does heat the water that's all I can say for it.. Stay away from A.O. Smith heaters...Customer service sucks!!!

Erg tevreden over het advies van Ao Smith. Ze dachten echt mee over wat voor ons de beste duurzame oplossing is

I just got to say they helped me out a lot. A bit of back and forth, and in the end Larry was amazing walked me through the checking of the electrical and we found out in the end the water heater was fine it was the switch I have above the water heater that turns the water heater on and off. The switch had arced and was 40 yrs old to. 😂. So new switch and checked the upper element for 240 volts. Got that, and Larry’s yr uncle😏. In no time we have hot water again. Thanks a ton Larry.

Horrible customer service and garbage products. Stay away
