Excellent Service (About the AO Smith GPVT-50)

Review by on Sunday, November 2, 2014

The delivery people were excellent.
The installation was not a problem as this replaced a similar 20 year old ProMax unit. The new water heater performs as expected

2.7 / 5

customer service great, heater a pain (About the AO Smith GPVT-50)

Review by on Wednesday, June 4, 2014

I am on my 3 or 4 vapor sensor for my AO Smith propane, blower, 50 gallon hot water heater. It keeps shutting the unit off after any where from 3 months to 8 months. They tell me it is sensing something however my 40 gal. other maker heater that sits right beside it keeps running. The ohms are too high for it to reset, I dry it, I let it get fresh air and nothing. The fourth sensor just arrived, I would not recommend this unit.

Customer Service Was Great and Product Arrived Exactly As Planned (About the AO Smith GPVT-50)

Review by on Thursday, June 14, 2012

From the beginning of the process. Dave Schlesinger, my main customer service contact was great. He answered all my product questions or if he needed to confirm inventory availability or shipping/ETA information he would contact the right people and get me the answers I needed ASAP. I'd have to say that the follow-up was great during the order and also throughout the whole process. The pricing was the best on the internet and on top of that I didn't have to pay shipping or any sales tax. This made it a no brainer for me. I got the item in excellent condition and was able to replace my existing hotwater heater just in the nick of time before it died completely.
