What Customers Are Saying
The AO Smith heat pump water heater has experienced significant reliability issues, with many customers reporting the compressor failing within 1-2 years. This causes the unit to revert to less efficient electric-only mode, negating the energy savings benefits. Customers have also faced challenges with the warranty coverage, often having to pay hundreds or thousands of dollars out-of-pocket for repairs. There are additional quality control problems, such as leaks, strange odors, and issues with smart home connectivity. While some customers are satisfied with the performance when working properly, the widespread reliability problems and poor customer support make this an undesirable product.
Customer review summary generated by AI, including incentivized reviews.Lasted a little over a year
Absolutely one of the worst things ive purchased, did my electric bill go down? Absolutely, mainly because it locked down every day with error codes related to the heat pump and wasn't working. Did call for warranty and the charge to get the guy here was more than the water heater. You see they don't pay for the visit and the closest approved company was 3 hours away.
Easy setup and great product. Love the wifi.
Great price after rebate through Oncor!

Compressor and LOWE's Protection Plan Failed
Hey! Purchased the unit and the Lowe's Protection Plan / Service Agreement less than 2 years ago. The compressor failed and so I filed a claim with the Lowe's Protection Plan website. They just let me know that they won't cover any service. I paid for a "Service Contract". Not a refund contract. The unit is still covered by A.O. Smith's warranty. I don't need a "buyout" from Assurant. I purchased a "Service Contract". Hey Lowe's, Is this what you deem acceptable? Here's of the email. ...

Loud Banging Noise
Buyer Beware! This unit makes a loud bang and causes sudden water pressure drop during times of high water usage and/or recovery. Very unsettling noise that will make you jump from multiple rooms away in the house or awaken you from sleeping. This noise has been present since the installation. After contacting A.O.Smith tech support and providing them video of the noise with significant gauged pressure drop, they claim that this is completely normal noise and operation and therefore refuse t...

Not reliable - Do not buy
So, I bought a new AO Smith Heat pump water heater back in 2023. In 9-month it broke. The Heat Pump stopped working. After jumping through all the hoops sending pictures etc. I got a brand-new AO Smith heat pump water heater. 18 months later the new water heater broke. AO Smith is willing to replace it but now I am out the install and disposal fee. It was only 27 months and now I will have replaced the unit twice and I am out a second install! AO Smith needs to make products that work and stand...

Do Not Purchase
We have purchased two of these water heaters from Lowes and AO Smith, and the heat pump has died again! Same failure both times. AO Smith may replace the unit, but no one covers the cost of install and haul away. It costs us hundreds of dollars each time this water heater dies. Our previous heat pump water heater, a GE Geospring, latest 10 years with no issues. Lowes, AO Smith...do better by your customers. This unit is a lemon.

So Much for Saving
While advertising great savings, it will be lost on the 1st service call. Do yourself a favor before you purchase call their support line early in the morning. Chances are you will have 50 to 60 callers in line before you. They force u to have a tech look at it, before they honor warranty.

Reliability issue
I would give it 0 stars if I could. We got this in October 2022 and it failed in April 2024 for compressor issues. The unit was covered under warranty, but labor wasn't, costing additional $2500. We got another one installed in October 2024 and guess what, it failed again in February 2026. Avoid this company at all costs.
