"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."

"I contacted Home Advisor late one night after my water heater gave out. Cliff contacted me the very next morning, telling me he'd be at my home within a few hours. He arrived, inspected my water heater, diagnosed the problem as the unit needed to be replaced, and replaced the unit. Now, My water is hotter than it's ever been in the time I've lived here and the pressure is greater than I've ever seen."

"SILA is never going to be the cheapest but if you want something diagnosed swiftly and fixed or replaced just as quickly, you can't go wrong with these guys. They were the only ones to correctly diagnosis and fix our ailing furnace three years ago, so we trust them. For this problem, they tried to get the old pump into working order (turns out it was the kind that needed to be oiled; the contractor, not SILA, who installed it along with a heavy duty basement dehumidifier, never told us it needed oiling for routine maintenance). The SILA tech did all the diagnostics on the drain hose (no blockage there) and then tried oiling the motor. It was running but not well enough to push the water up the hose and down the drain. A new pump was the last alternative. Within 20 minutes, the SILA tech replaced the pump with one identical to our furnace condensate pump, which never needs oiling. Everything is working fine now! They also have good coupons/deals when you get on their email/mailing list."

"Outstanding professional service all around by N & J Plumbing from the moment I was contacted by Nick on a Saturday (when my water heater began leaking), who initially guided me on the phone as to the actions I needed to take to gradually stop the leak - until the replacement of my water heater on Monday by Nickâ s team."

"I rated them B for responsiveness because the first time I called I was told they would call back and they did not. As you would expect the price was too high. They ended up tightening a union of pipes and testing to see if it leaked. The first time it was tightened, it did leak and they went to replace the part. A second tech tightened it further, retested and it did not leak.Not sure why the first person didn't tighten further. So the question remains; is the problem solved. We will see when the heating season begins. The techs were young, personable and seemed knowledgeable and willing to answer all my questions. They spent over two hours here, some of it waiting to get the heating up for testing. Had a $50.00 coupon or the cost would have been over $400."

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