On my 3rd AO Smith heat pump water heater in 3 years. Very Discouraging! I’m not sure what is going on in there factory, but these heat pump water heaters are junk and this will be my last one. I’ve been told that several heat pump water heaters made by AO Smith and installed in my area are having similar issues. This is happening in the state of Maine.The unit keeps throwing an error code or the compressor is faulty.The anode rods are also part of their failure. My hot water smells like rotten eggs, never have I smelled that only since the heat pump was installed.They just dissolve inside of the tank, what a mess. When I drained the tank to remove from my basement the liquid that came out of the bottom reminds me of gray wall paper paste.Would not Recommend!!!!!!

Stay away from the A O Smith Vertex. I just replaced this water heater after 8 years. I had six service calls on the unit over the ownership period. Everything from rust inhibiting operation in the first two years, to an igniter going out to ultimately a bad blower vent motor vibrating so much it caused the wires to come out of the plastic clip. I called A O Smith about replacing the blower motor and they wanted $1500. I don’t know how a company can produce a product with so many flaws and have the indecency to charge half the price of the water heater to replace the blower motor. My parents had an A O Smith and also had many issues. I will never buy an A O Smith product again.

I called the technical assistance number listed in the manual. I asked to get a part NUMBER for the anode rod on a water heater. They required I provide them with name, address, phone number, location in the house of the water heater, serial number, model number, and who installed it. This amount of information is ABSURD to get a part number for a non warranty part. Anode rod can be bought at a local hardware store. After multiple conversations, I was told it was due to gas regulations. Not true. I called a supply distributor and ordered the part before even being asked my name. Ao smith kept referring me by a name I stopped using (get this) 33 YEARS ago. When asked where they got the name, they refused. No need to wonder how my identity was hacked.

Purchased a Natural gas hw heater from Lowes with a 6 yr.warranty. Working in the industry for 30 yrs. I installed it myself and maintained it regularly ! After less than 3 yrs, the water I regularly drained from it began to show rust and showed leakage in the drain pan ! Warranty staff instructed me to remove it and return to Lowes for replacement and pay the difference in cost !!!! REALLY !! Keep your warranty ! I'll never buy your products again !!

I purchased and installed an AO Smith Signature 100 water heater in June 2022. About a year later, the electric panel circuit braker started to trigger, causing the water to go cold. After contacting an electrician and conducting a review, it was determined the water heater was defective. I went to the manufacture's website and contacted one of their approved technical support companies. I called New York Cooling Corporation (843) 458-1302 for warranty service. After verifying some information about the heater, the representative informed me the service was not covered under warranty, only the parts. The warranty flat fee was $250, parts would be covered. I agreed and scheduled an appointment for the following Friday, the first opening available. On Friday late in the afternoon, I texted the technician who then informed me he was not going to be able to come to service the unit because his previous job had taken longer than anticipated. Finally, when the water heater was serviced, the upper heating element was 100% corroded and malfunctioned. It is IMPOSSIBLE the heating element would be in this condition in only one year of use, which makes me come to the conclusion this was a poorly refurbished water heater that I paid as new. Unfortunately, this is not a reliable product, lacking good warranty service and has poor quality control.

Water heater is less than 3 months old and it will not let the hot water be of any temperature other than "ULTRA HOT". Called AO Smith and they will cover up to 100 dollars for a plumber to come out to replace the control. We paid over 750 dollars for this piece of crap and apparently it is only worth 100 dollars. The people I spoke with were very nice but could not do anything for us except say do you want to speak to a supervisor. DO NOT BUY ANYTHING THIS COMPANY SELLS OR MAKES!!! As far as sending this to AO Smith they just don't give a @#$% about either their reputation or the customer. Hope what happened to Bud Light happens to AO Smith.

8 months in and the pressure relief valve is leaking. Wont cover under warranty. Total trash tank and customer service is another joke of its own.

purchased an A.O. Smith hot water heater on 7/21/2023. Water would not get hot. On 7/22/2023 was told by support to replace upper thermostat and upper heat element water is now warm, still no hot water. Was then told by support to replace the lower heat element, which was done and still only warm water. I will swallow my loses and purchase a reputable hot water heater and get it installed. I will also no longer do any business with Lowe's who sold me this piece of junk.
