One of the worst companies I’ve ever had to deal with. Bought their water heater on 6-19-26 and installed it the same day. Immediately through an error code. The company stated the gas control valve needed to be replaced. They gave me two businesses to obtain the part from and gave me a payment authorization code for the company to be reimbursed. First company said they don’t carry the part. The second company said they have the part, but they will not do the reimbursement, because AO Smith doesn’t reimburse them. Contacted the company again, told me to purchase the part and they would reimburse me. Well if you deny reimbursing the company, what makes me think you’re going to reimburse me.

Junk mixed with/scam warranty made to discourage and disqualify. Lengthy and painful. Just know it is a crap shoot IF it last the length of warranty they claim on the box. Expect ZERO customer support! It's yours when you walk out the door.. Maybe it works. Maybe you got 500$ of scrap.. Good luck.

Horrible service. They rather children and elderly go with out hot water than honor their warranty and replace a hot water heater saying they need to fix it first and take days to do it. Horrible. Horrible. I want to return the 4 hot water heaters I just bought. Never again.

My AO Smith 50 gal water heater lasted just over 3 years. Rusted out from the bottom. Complete garbage. Company should be ashamed.

Worst Customer Service & Complete Warranty Failure! Avoid A. O. Smith! If I could give 0 stars, I would. We installed a brand new A. O. Smith tankless water heater (Model THR-199M) in December 2025. It completely failed in less than 6 months, leaving our household with NO HOT WATER—a total living emergency. Their "manufacturer's warranty" is an absolute joke. Their customer service department wasted days of our time. They provided a list of authorized plumbers under warranty, but every single one of them refused to come, stating our area is completely outside their service range! Because A.O. Smith's service network failed, we were forced to pay $500 out of pocket just for a private technician to diagnose their defective product (Case 19773419). Now, because they have no local plumbers, we are being quoted an additional $1,000 for labor to install the replacement part.
When escalated to a supervisor, they offered a ridiculous reimbursement rate of $65/hour, which doesn't exist anywhere in the market, admitting their own network doesn't cover our area but refusing to take financial responsibility. They are in breach of their own warranty, leaving families stranded without basic utilities. Do not buy their products unless you want to spend thousands of dollars fixing a brand-new appliance yourself!

The worst customer service I ever encountered. I requested to speak to Supervisor, placed numerous messages, spoke to service department. No person ever calls you back. You get robo calls that go to message box & then the whole process repeats again. My 1st HWH gas operated came with the brand new house in September 2019, lasted 4 years & then leaked & had to be replaced-I covered the cost of labor that was around $ 800.
The replaced new unit, installed on 4/20/2023 failed only after 3 years. AO Smith doesn't take any responsibility for two units failure in just 7 Years. Talking to customer service is extremely frustrating & it doesn't accomplish anything. They have my case number (**) & completely ignored my requests to speak to the Supervisor or Manager. I share this experience on line in hope that I finally get response from AO Smith. Is AO Smith Company stands behind their product or not?

Bought a gas water heater 1 month ago ... Today it stopped working... Went thru lowes (bought from). That was an experience.. Was transferred to A O Smith customer service.. Was told that I needed to contact a plumber at my cost to troubleshoot the unit.. then they would move forward.... Wonderful process, in the meantime we have no hot water.

I wish I could give a negative five! Bought brand new AO water heater at my local Lowe's. Now myself and husband are not newbies to the world and over many years have replaced water heaters and parts to them. Now that being said my husband installed ours properly and made sure of all of our worong and he bleed the air properly. Turn on, nothing! So call Lowe's. The manager told us to call them. They will walk thru a test to make sure then if bad issue a replacement. Ok nice but we live three hours round trip from nearest store. Plus pain In butt to drain and haul! So he does what they ask! Lady at AO nice, ask him to call back when in front of heater.
Well he was at work so local contractor comes to help. Calls and she tells him it's bad element so gives a RA code for part. So gonna have to make the long trip just for part. Ok fine ... He removes element... It is an old bent burned corroded element, the likes I never even saw in one years ago that was wore completely out. I call, man answers rudely this time. Proceeds to tell me it's our fault because we had to of dry fired it and we have corrupt water. Ummm Ewe K... No on all. He refused to help and talked down to me because I was female.
Contractor took my phone when hearing his attitude and engaged him. They had a back and forth and they hung up after he said we were out of luck. So husband calls back, gets nice lady. She tried to help but says only can do part replacement. So we load up, drove to Lowe's, ask for manager. He recognized us as he had sold us the heater. We handed him the old elements. He was appalled and says that's not dry fired nor water, that's a used water heater packaged as new....YUP! DO NOT BUY THEIR PRODUCTS. THEY ARE NO LONGER ETHICAL COMPANY!
