    Review of Thompson Plumbing Heating and Air Conditioning

    Recently our water heater’s pilot light went out. I knew how to re-light the pilot, but I didn’t plan on discovering a leak and an inch of water. Fortunately for me, I knew who to call: “Thompson Plumbing” and ask for Thomas! He is Great Plumber! He is Prompt, Professional, Knowledgeable, Efficient, Reliable, Dependable and Courteous. I know that my New Water Heater is Working Great and Installed “Expertly”. I will recommend Thompson to my Friends and call again, if the need arises. I hope it doesn’t, but I certainly know who to call.
