"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."

"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."

"We had a standard water tank that failed on Friday July 1. I reached out to Matt with water issues from the tank, but more importantly- to find out options for a replacement. He convinced me to go with a popular and reliable tankless system. I called him at 7:40am, the parts were delivered at 11am and Matt came by at 1pm. By 3:30pm, our new system was operational. Going into a holiday weekend - that was fantastic service!"

"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."

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