Isaac was the service tech and he was awesome. He talked me through what he was doing and why. He also showed me where to turn the propane off in case of an emegency. He was very friendly and knowledgeable. The only thing that was disappointing about the experience was that I was not given a window for an arrival time.
Service has been consistently good. A few months ago, the truck came to refill the tank, and the delivery man judged (I think correctly) that the tank needed to be replaced, told us, and left without filling it. The next day we had a new tank.
