"Guy Rizzo got back to me right away, came when said he would and fixed the problem-a dirty pilot gas line. The price was very reasonable. Guy is a straightforward, nice, fair guy. I would recommend him to anyone, including family and friends, that needs gas heat or hot water service and/or repair."

"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"

"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 would highly recommend C&A Mechanical. They were efficient, polite & professional. The quote given was exactly what we paid, which was very reasonable and competitive to other quotes. Craig actually offered to come assess our leaky water heater before our scheduled appointment, which was so helpful and definitely a huge factor for this job being done sooner than it would have been. We will absolutely call them again for service if anything else in our house needs attention that they specialize in."

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