Leaking from inside out

Leaking on top inside out

But the worst part is trying to get your money back from Lowe’s. I got connected online and chatted with Esther S., who told me I needed to wait a week to get another one. Then she said I needed to call the store, or that they would call me back… and she ended my chat while I was still typing, since they didn’t give me a reference number. Good luck with that. So, I called the store that delivered it, and they told me I needed to rent a truck. I explained that I paid the delivery fee because I do...

Customer Service Issue

Went to Lowe’s Binghamton today 1 pm to pick up a new hot water heater. Asked associate for help, she called for help to isle 10 and no one arrived. I waited. Nothing. I went and got a large flat cart and had to load it myself. Went to the counter to pay and I asked why no one came to help me. The associate said “ and don’t expect help loading it into your vehicle either!” I just couldn’t believe what I heard!

Go along with Lowe's policies, no worries.

Good.

Love it

I am so happy to have this water heater. As I was without hot water for months on end

Last one lasted 18 years

AO Smith must be the best Hot Water Tank on the market. Just had to buy another one and was surprised at the value pricing.

Beware of electrical fires

Beware of these units causing electrical fires!!!! We purchased the AO Smith water heater and the circuit board malfunctioned creating an electrical fire in the unit. AO Smith will not cover labor to replace the unit and customer service is unhelpful .

Great unit .. easy to install

Very easy to install. Have only had unit for few days, but am very pleased thus far.

Follow instructions

Light weight Easy to connect following instructions

Casing dented

Heater had a small dent in casing over bottom element.

Bad water heater

I bought this water heater on April 18, 2025 and had a certified plumber install it. It took over 24 hours to heat up and then it stopped heating up. This certified plumber and myself brought it back to Lowes for a refund. The manager said they would not accept this WH for a refund. I had to leave it there because the plumber left and I had no way to transport it. I call A.O. Smith several times and they said they wouldn't accept it without some type of "reading". A big waste of $440. Don't b...

Easy installation

AO Hot Water Heater

Having to buy another hot water heater after 19 months is very stressful. I noticed water leaking from the element box on the bottom. I called maintenance man who came out to look at it and said it wasn't leaking from the element and seen that the insulation was wet and water was running not just leaking from . Disappointed in quality of the Water heater.I’m not the only person that’s experienced the same problem with this A O hot water heater brand. I tried posting a video, but it will not ...

Never received after a month of waiting!

Never received after a month on order! I ordered this water heater to replace our 20 year old heater for home owners insurance and after a month of waiting, 3 calls to customer service and two trips to the store the water heater was lost and never delivered. I had to scramble last minute to purchase and install a different water heater and pay twice as much. Customer service was very unhelpful, and I was told three different stories along the way. This experience has made me rethink ordering any...

Horrible experience with Lowe's Installation

Terrible experience with Lowe's Installation. The installer damaged the unit, then tried to hide it by taping the manual over the damage. Worse yet, Lowe's Installation support refused responsibility and even suggested I falsely claim a manufacturing defect. Shameful service and disappointing product—my old 15-year-old heater performed better (shouldn't have replaced it, it worked well).
