"Replaced a tank water heater, the door was too narrow so first pitched removing framing with no guarantee that it’d be replaced correctly. I suggested using a smaller sized unit based on a quote from another plumber which is the route we went. They also covered the overage for the additional cost of the smaller sized unit which was nice but if I wasn’t aware of the option I’m not sure what I would have done. They also only sent one person initially so I helped bring the old unit down and the new one up in between trying to work. Also the breaker to the hot water heater was never flipped back so I’m waiting to see how the unit performs now."

"The Sila technician spent as much time as necessary to diagnose the problem with my furnace. He explained his findings every step of the way. Communication from the company regarding service visits and arrival of parts from their distributor was excellent. The cost of the repair was reasonable. Overall, I was very impressed by Sila and would definitely use them again."

"I had an issue with my stream boiler last Saturday. Did a google search and called multiple companies except Lighthouse (also part of Premier HVAC) picked up the phone right away and the tech Slava (unsure if I spelled his name correctly) showed up an hour after my call. He was very knowledgeable. He first did a thorough inspection on my streamer boiler (I thought mine was called furnace but he corrected me and luckily Lighthouse also repair stream boiler), then giving options (replace the water feeder and side glass or the whole stream boiler since mine was already past 30years and it may not last long). Due to budget issue, after discussed with my family, we chose for now just changed the parts. Slava has no problem with that and I got lucky that he was about to arrange time to have the work done the same day. Slava is also very patient and professional. As he learned that I am new to streamer boiler, while he was doing his work, at the same time, he was giving “a lecture “ in terms of names, functions of each parts and the concept of how the stream boiler works and how to maintain it properly. I gotta be honest that I don’t recall all the he mentioned but at least now I have a concept. In terms of the price, I can’t say that it’s cheap but you pay for the quality of service that you get. Slava literally taking his time and spent about 4 hours to repair. Highly recommend."

"I had the equipment replaced, a brand new, super high efficiency, fancy, lovely stuff. It's a central air system, and it's Lennox equipment. It's high efficiency. You can get it for less than that, but you're not gonna get the high efficiency quiet and all that kind of stuff. I had received other quotes which were like more money for the same system. I have been using them since 1986. No complaints. They do their thing, and I can't fault them. I have a service contract with them for this."

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