The technician did not arrive on time
The technician did not arrive on time, and there was no proper update regarding the delay. The service was not carried out properly, and overall, I am not satisfied with the experience.

Warranty support is a problem
My 5-month old A. O. Smith water heater (50-gallon. natural gas ProLine) stopped working last week. The pilot light couldn't be restarted and the status light was dead. It turned out to be a defective thermopile. Unfortunately, A. O. Smith doesn't have an authorized warranty service in my area (I'm in a heavily populated area of NJ near NYC). I had to pay my own plumber for several visits to diagnose the problem and replace the defective thermopile (while we were without hot water for 5 days). Happily, my complaints to customer service were resolved eventually, with A. O. Smith reimbursing me. Ultimately they stood behind the product.
