"As soon as I went on Angieâ s list they contacted me. He asked for pictures of our hot water heater and all the documentation on it. By the end of the day he sent me a quote for two different models. The night before he came to install the new heater he asked to see it to be sure he would have everything he needed. Mr. Rizzo is an excellent plumber and a pleasure to work with. He covered all the floors I would definitely recommend him. He was a rare find!"

I'm extremely satisfied with with the results, I will always have Varsity for my home services. Varsity earlier this year installed a walk in shower for me. The results were fantastic. In the future I will have Varsity install a hot water heater."

"I am very happy that I hired Patience HVAC to replace my hot water heater. I have an oil burner and oil hot water heater. The 18 year old heater was making crackling noises and I was advised by the oil company to replace it. I wanted to convert to a gas hot water heater and tried going through Lowes. However, they only do swap outs if the existing heater is already set up for gas. So I contacted several companies for a quote. Out of all of them, Anthony was the most professional, down to earth and reasonably priced. First, he suggested to explore correcting the issue on the old heater and save me money which was impressive. I decided to proceed with a new gas heater. The quote he gave me was $800 less than the next lowest quote. Anthony sent his workers Caesar and Matt the next day which I greatly appreciated. They were both very polite and wore covers on their shoes so to avoid dirtying my house more than necessary. Anthony came later in the day to ensure everything was done correctly. He then offered to call him with any questions even if they were not pertinent to the work they performed. I am extremely impressed with patience HVAC honesty, professionalism and reasonable prices. I will be sure to recommend them to friends and family. When I am ready to install a ductless air conditioner, I will definitely contact Patience HVAC."

"JTC services plus absolutely exceeded my expectations. Iâ ve had a leak in my fireplace for the last five years hired two other companies to diagnose it . They made repairs and neither one of the companies fixed it. Jeff was able to find the problem in about 15 minutes. he fixed it and assured me that the next time it rained I would not have any water coming in my fireplace, I waited to write this review just to make sure everything was exactly the way he said it would be and sure enough no leak !!! I was so happy because it would make my fireplace smell and also kept producing this white stuff which I think he said it was called efflorescence . Not only did he repair the leak in my fireplace. He was also able to pinpoint that the top of my crown was cracked, and I had a major problem inside of my heating flu. I had my chimne relined with stainless steel. He was able to give me a lifetime warranty and also a five year warranty with the masonry. I have to say I am truly impressed. They were very clean in and out and the pricing was perfect. I would definitely recommend JTC services plus to anybody who would like , a solid job !!!!"

FAQs for water heater repair or service projects in West Islip, NY

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.
