this is my 3ed AO Smith hybrid, 10 yr warranty, in 4 years

Failure after 2 years

I saw a lot of negative reviews before I bought this, thinking I may be lucky enough to not hit a failure. I was wrong. It indeed failed after 2 years. Called AO Smith, they gave me an RMA number for exchange of the identical unit. But they won’t cover the labor to uninstall and re-install. So to get a plumber to do that job it costs 2k in the Bay Area. More expensive than the unit itself. If this thing is saving me $340 per year this essentially eliminate 5 years of energy savings. The instal...

Heating Element bad after 15 months

The heating element on this water heater went out in less than 15 months. The extended warranty will cover this but I'm informed there are no service technicians in my area.

Worked 2 years

Purchased this water heater in October 2023, and in October 2025 here we are: the heat pump failed. Contacted a local plumber to have it fixed: the water heater is under warranty, but it will cost me almost $1000 to have the AO Smith defective product replaced !!! I've contacted AO Smith to know if they plan to help customers having issues with their products of particularly poor quality (lasting only a fraction of their expected lifespan), and the answer was clear: no. My 2 cents: expect a peri...

Worth the extra money

this is my second one -- works well

Thanks to Lowe's for giving me a 100% refund.

I returned it to Lowe's because of so many lousy product reviews from consumers who had purchased this water heater. There was not one single positive review.

Water heater fine but app doesn’t work

The water heater seems to work fine but the app to control the features does not work. After reading reviews, I can see that people have been having trouble with this products app for over two years. There seems to be no resolution. I would recommend you purchase the lower priced water heater because you will have to control the features manually anyway.

Working As Expected

I purchased with the expectation that it would use much less energy than my old existing electric water heater. I have an energy monitor that I use to track energy usage of various appliances. Over a few weeks this heat pump water heater has used on average 20% of the energy of my old water heater. My old one needed about 3500 Watthours per day while the new one only 700 watthours. I do live in Florida and the water heater is located in our garage, a relatively warm location. Nevertheless the en...

Garbage product, poor warrantee

Worked for less than 1.5 yrs and after jumping through a bunch of hoops to get customer service to honor the warranty ( took me almost 4 months), it was replaced. The replacement lasted 2 years with only the carry over warranty for the original tank. Plumbers who were required to come out and service said they see so many problems with this company and they were surprised I was able to get them to honor the warranty bc usually they do not. Will not buy AOSmith again.
