Customer Service Issue

Would Recommend

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!

Bang for the Buck$$$

Would Recommend

My Rheem finally corroded at the base and I was able to purchase this brand new unit. Selection was a breeze and so was the installation. I re checked for leaks days after installation and have NOT had an issue. The unit supplies enough hot water for 2 teenagers to shower at the same time. Unbelievable!!!

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.

I did it myself!

Would Recommend

Just purchased a 50 gallon water heater, electric and followed the directions. It was fairly easy, using shark bite connectors. This was my first water heater installation and the first time I read the directions first!

Beware of electrical fires

Would Not Recommend

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 .

Works as expected

Installed yesterday. Was taller than expected, just had to get longer pipes to make the connections. Otherwise, it was easy to setup, works great so far.
