So far so good

Would Recommend

only installed a month and so far so good we shall see. The guys at Lowes were very helpful and polite. None on the floor but in stock on the high shelf and they worked quickly to get one for me then checked me out right there. Now that was easy!

Ridiculous!

Would Not Recommend

$600 for a $300 water heater that won't last 10 years. Absolutely Pathetic!!!

Anode unable to be changed

Would Not Recommend

Heater is 2 months old and cannot change zinc anode to aluminum even with 800 ftlb dewalt impact wrench. of course Lowes does not support the product and referred to AO smith who does not have a page on website to start warranty claim. Good grief what a joke

Main water heater

Would Recommend

We’ve had the water heater for 5 months. Installation was pretty easy, wish the recessed box for the electrical connection was larger; it was challenging to get the wire connection pushed in enough to get the box lid on. It’s working fine.

HORRID EXPERIENCE

I Purchased this hot water heater on. July 8th of 2026. When they delivered, I noticed the box was broken at the bottom. I asked about it and since they weren't installing it, they said, "when you open the box, if you find damage, just call Lowe's." After they left, I put my hand in the box and found it was definitely dented in two places. I later looked at the email the driver sent me from the warehouse and there was a photo of my washer and my water heater. The water heater box was already d...
