Recent Review: Mr. Jenny gave us a fair, fast, free estimate, was patient while we decided which contractor to use, and then finished the work on short notice when we needed a rush job. He gave us honest information on the appropriateness of each type of water heater we considered. He was on time, professional in everything, and respectful of our home (didn't leave tracks, etc). The job looked neat and everything was tidy and locked up when he was finished. For no extra charge, he inspected the piping system in our old house to help us determine if any lead pipe was used. However, the heater stopped working the next day. It was a holiday and he showed up immediately to assist us with the problem and replace a sensor. The next day, the heater didn't work again, showing an error that indicated flammable vapors in our basement. Mr. Jenny sent a service rep from the company who made the heater and he replaced another sensor. It's worked fine ever since. We're pretty sure it wasn't the water heater at all, but an old toilet in the basement that had no water in it...maybe it was leaking methane from the sewer? Nonetheless, both Mr. Jenny and the manufacturer showed great reliability and responsiveness in helping us solve the problem. From now on, we'll keep some water in that old toilet though!
