"I received a call back promptly. Tom couldn t have been more helpful to me from walking me through shutting the water and the electricity to my water heater off. He gave me a fair deal on a new water heater made me the first appointment of the day because of having my son in the house and came promptly on time and finished the job very quickly. I really appreciate everything he did for my family and would recommend him to anyone."

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"Service was performed on time while meeting my expectations. The plumber (Felipe) was very professional and answered my questions before and during the process. No mess, all cleaned at completion with a very good looking new hot water heater. All in all we are very satisfied. Yes, I would definitely use again. Highly recommend."

"Thank you HomeAdvisor! I spoke with them late on a Saturday and by Monday afternoon my new hot water heater was installed. They shopped around to get me the best price on the equipment I needed and were so kind to keep me informed as to their arrival time. They did a fantastic job getting out the old and installing the new, I am super happy!!! I would definitely recommend them! Thank you Mike and Todd!!!"

FAQs for water heater repair or service projects in Seymour, CT

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
