"My oil delivery line has gelled up and was blocking my furnace from getting oil. I sat in the cold for 2 days while calling a few companies who claimed they provided 'emergency' service 24 hours a day. Whenever I was able to get a live person on the phone they promised to be here the next day between certain hours. The hours came and went and not a single soul called me or came. I called Moh on Monday night and explained my situation and let him know that I didn't have any heat. He promptly sent me a text telling me he's be here by 10am the next day. He showed up at EXACTLY the time he said he would and immediately went to work. He cleared my oil line AND changed my mucked up furnace nozzles that hadn't been changed in years. He was quick, knowledgeable and took him time resolving my issue. He also suggested that I change to gas heat and I'm definitely going to use his company in the spring to do just that. I called him today because my filter is leaking a little and he's going to come back soon to resolve it. I HIGHLY recommend this company and particularly Moh. He's my go to guy from now on!"

"Great. They showed up on time Wednesday morning; done and gone before noon. Both the water heater and the garbage disposal work really well; they took the old stuff away. Work was professional."

"Chris replaced gas water heater, re-plumbed washing machine discharge, replaced all sink water supply valves and hoses in home and apartment. He was completely professional, on time, very good communication and did an excellent job for a fair price. I would definitely use him exclusively and I have already recommended him to others"

"Called on a Sunday evening and there was a serviceman at my door by 8 AM Monday morning. Mike, the serviceman, was extremely knowledgeable, professional and courteous. Will recommend this company to anyone I know who needs air conditioning or servicing. Thanks again for the speedy service and knowledgeable serviceman who repaired the air conditioner quickly!"

"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."

"For my central A/C install. Varsity is the gold standard for professional service. Varsity works as a team who patiently brought me through the process from start to finish. 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 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 East 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.
