    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.

    I write reviews when they are deserved and this one is! Thomas B. Is a Professional, Courteous, Experienced Plumber who is a great Representative for Thompson Plumbing. He arrived on time well within the time frame. He explained his companies policies and took the time to listen to my concerns. He assessed my plumbing problem, quoted me a fair quote and he began. Regrettably the job turned out to be more challenging than expected, but he was not deterred. He kept me informed and he expertly remedied the problem. I was impressed with the: His Service, Knowledge, Expertise, Demeanor and Professionalism. I have found “My” Plumber! It is a relief to find a Reliable and Trustworthy Company. “Bravo Zulu, Thomas!

    Cooling maintenance. Filter is a trance clean fx. Cleaned pre filter and cells, reset the filter display and it is functioning. Performed a cooling maintenance and the only thing that needs to be done as of now is to add a hard start kit. LRA is high and customer has been advised of the situation. Sent an estimate for the hard start kit addition. Estimate prices are subject to change over time.
