"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."

"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!"

"Brian installed a toilet for me in March of 2022; in 2021 he installed 2 sinks, a second toilet and a hot water tank. This plumber arrives to the job in a sizeable truck in which he inventories most parts any plumbing job. Apart working with expediency and skill Brian holds accounts with several local plumbing supply concerns in which he is entitled to at a â plumberâ s discountâ for supplies. As a result, Brian was able to purchase my new sink for $38 below the Amazon price. In general, Brian is a seasoned plumber who is able to pass cost savings onto his customers by virtue of working expediently and competently, and an ability to purchase plumbing appliances for a significant discount. His work is impeccable and I highly recommend him for any and all plumbing repairs and installations."

"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 New Canaan, 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.
