From the initial visit and estimate to the repairs, Donnie, Daniel, and PJ were friendly and professional. They showed me where they wanted to add tape around the vent on the water heater to be sure there was no CO2 leaking out. They even took my old water heater. I plan to use Tom Drexler for my plumbing, heating, air, and electrical. If the other techs are as friendly and professional as these 3 were, you'll have all my business. Thanks.
