"We initially needed a plumber to fix our broken diverter in our main bathroom along with some other plumbing fixes. Chris had given me a quote over the phone which he stuck to. While he was fixing the shower, he noted some "brown" on the shower head. My husband also complained about the water pressure. When they went down to the basement, they saw that the water heater was going to break, since the water was black. He gave us a quote which included a 50 gallon water heater (10 gallons more than what we had) including installation and hauling off our current water heater, which was over 12 years old). We agreed to do immediately to do this, he ordered it and within a day or two, it was installed! It took us a long time to find a reliable plumber, we found one! Thanks Chris!"

"Barbara was excellent. She found the leak and made the repairs and so far so good. Barbara explained our options clearly and she stuck with the job until it was done to both our satisfaction and she didn’t leave a mess. The leak from the toilet is gone and our new faucet is working perfectly. My daughter thought it was great that the lady plumber fixed everything. We would definitely use her services again. Thanks for your patience and your work Barbara."

"They were super helpful from the get-go - we had the issue with our water heater at 4PM and were frantically trying to stop the leaks and also figure out who to get to help, and they called us back the same day and worked with us to get an appointment the next morning. They came and removed the dead water heater, got the new water heater we wanted installed and working, kept in touch through all our follow up questions and checked in on us ar night. Can't recommend them enough."

"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!"

"Chris and his co-worker were very good. My hot water heater was in a very tight space. With that being said they did a nice job on the sodering. Chris replaced a valve he didn’t like. They did a great job cleaning up. Once installed and powered up they waited outside for 30 minutes to make sure the water got hot."

"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."

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