"I called All Weather to give me a quote for replacing my gas boiler. They set up a time for their salesperson to come over and give me a quote. The appointment was only a few days later and a man named Joe showed up on time. He spent some time with me, I told him I was looking for a new boiler and a new hot water heater, but I wanted to see what options I have (since I was debating going to a tankless water heater). He told me going indirect hot water tank is the best option and they always use this brand that's the "best one out there". Even though he may have been right, he didn't tend to my questions or concerns very well. I felt like he was getting annoyed that I had questions and eventually I just let him run the show just to get him out of my house faster. Especially when he gave me a quote of $8600, it was much higher than I was anticipating. One thing I really didn't like was when he said I'd have to get a permit since I live in an incorporated village, which would be an extra $500, meanwhile I already had another plumber tell me a permits only $200. So I went with another company. So even though I can't rate All Weather on their work quality, I didn't get a good feeling from their salesperson."

"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."

"I am very happy with the service I received from Varsity Home Service today. I was given an arrival time and the installation team showed up on time and worked neatly with respect for my home. I had two Fujitsu Air Conditioners/Heaters installed and it has changed the level of comfort in my home instantly. Kevin, Tom and Colin were friendly, engaged and did an amazing job. I barely knew they were here. Before they left they showed everything I needed to know about my new units. I highly recommend Varsity Home Service and the Fujitsu Air Conditioning Unit."

FAQs for water heater repair or service projects in 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.
