"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."

"SILA called to offer their annual heating inspection services given that I was a prior customer. The gentlemen they sent, Ivan, was very knowledgeable and thorough. He went over and above, and spent a lot of time explaining the parts of my boiler to me and likely failure points, gave some recommendations on my aging indirect water tank, and even answered a few questions I had regarding thermostat wiring. He was very patient, and left everything clean and exactly the same was as he had found it. He wore a mask, covered his shoes, and was very respectful. I've used SILA for my annual inspection every year the past five or so years."

"Affordable HVAC repair service. You can actually ask them to do little extras at no additional cost. After I called them for emergency repair of our AC unit, they offered a complementary cleaning for the unit. Amazing customer appreciation. Totally recommended!"

"Excellent customer service. My Hot water heater busted on Christmas night and i called advanced professional 26th early morning, tech at my home in no time to provide estimate and work was done within next 4-6 hours. Technician name Abe who came to my house for service is one of the best. Very polite, professional and make sure work is done neat and clean. Only one thing i am not happy is i think it was little pricey but since it was urgent service i can't complain."

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.
