"They contacted me right away, set up an appointment, came and did a wonderful presentation that was on a Tuesday. I had other contractors in between. They already sent me their estimates. I waited till that Saturday. And I emailed him, that I wanted to get his estimate. Never received anything. The following Monday, I called his number. He never got back with me. I told him what I wanted. He never got back to me. On Tuesday, which would have been a week after he was here. I called H L Bowman, and spoke with somebody there. She said she would check into it, and she would have an estimate to me within a day or two. And they never got back with me. I never got an estimate. And we checked our email address. Make sure everything was good. Never received anything. And here it is like, over two weeks later and havent heard a word from them. "

"This was the worst experience i have ever had with a company. They came and damaged my house and kept us without AC for days. They admitted to the extensive damage and went weeks before attempting to repair it. The services were never fully completed and they were paid over 90% of the job. I disputed the last 10% and provided overwhelming evidence of their negligence. And after a year their last ditch effort was to send collections letters. Don't walk, RUN from this company. I will provide pics and my my experience to anyone who is planning on using this company. Used to be family owned and was amazing. Second they sold it went downhill fast."

"Finding a reliable contractor is tough these days, but I got lucky hiring Chris. He and his son arrived on time, replaced my electric hot water tank, fixed a leaking guest bathroom sink, and cleaned up afterwards. Chris is a true professional with a great attitude excellent work at a fair price. I highly recommend him."

"They installed a minisplit cooling system, with 3 exchanges June 2021. Since then it is not operating the way it should. In my bedroom with the door closed at night on cool at 70 degrees the humidity goes up to 80%. I wake up uncomfortable, change it from cool to dry mode. The humidity will go down into the 50% range but the temperature drops down to 62 or less! So in cool or dry mode I can't get a good nights sleep! They come and look at it and tell me everything is fine. I'm going to buy a window air conditioner tomorrow which seems insane because i spent $10,000 on this minisplit AC system!"

"I had a great experience with Premier HVAC replacing my old and leaking water heater. I was impressed that they were able to respond quickly and start working on the same day as my call, especially given the severely cold weather and other plumbers being busy replacing freezing pipes. The plumber was able to work with my very tight kitchen space and narrow hallways, and without having to remove the countertop in my kitchen. I am satisfied with the installation and would definitely consider Premier HVAC for future plumbing needs."

FAQs for water heater repair or service projects in Norwalk, 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.
