"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!"

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

"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."

"We contacted Berardi Electricals through Angi, and Leo reached out to us right away.Leo came to our house within an hour, quickly identified the issue as water damage to the main electrical box, and explained that it was an emergency situation. He returned the following week, exactly as discussed, despite bad weather, and efficiently moved the box, repaired the wiring, and provided temporary electricity until the next day. His work was exceptionally clean, efficient, and thorough, and he took the time to give us the right advice, possibly saving us from an electrical fire. We found him to be honest, knowledgeable, and true to his word. We would highly recommend Berardi Electricals to anyone looking for a trustworthy electrical work."

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.
