"Company was very communicative. Technician was professional and helpful. Initial diagnosis and attempted repair of hot water heater was not successful, causing me to pay for a new unit in addition to the failed repair."

Customers say: True professional

"We had several different technicians working on installing a new water heater in a crawl space. There were several different unexpected occurrences that arose, but the guys were great. They were respectful, curious, helpful, understanding, knowledgeable and extremely patient explaining our oppositions. They were responsive and prompt to some unexpected situations. Highly recommend them, I'm giving the technicians ten stars for their professional and respectful work ethics."

In 1993, Tom Raynor began taking on electrical construction and service jobs across southern New Jersey. With just one assistant and one beat-up truck, Tom crisscrossed the state, building a reputation for his small outfit as one that offered professional, hands-on service and reliable, high-quality results. By 1994, it was official—Raynor Services was born! \n \nSince then, that red pick-up has been upgraded to a fleet of ten fully stocked trucks. We are now a “one-stop shop” service company, specializing in electric, heating, cooling, and generator services. Raynor Services has never lost the spirit of professional, hands-on service that it was founded on. Family-owned and operated, we combine small-business service with big-business expertise. \n \nRaynor technicians are among the best in the industry. Each must complete a rigorous hiring process – including a background check, a drug test, and an HVAC or electrical proficiency examination.

"We moved to new house recently and found that water heater has stopped working We called many plumbers to check the issue but everyone asked to replace it Andrew Stewart took a pragmatic approach to first try to clean the plate underneath and purged the gas, checked the gas pressure. His expertise lead the water heater started working again without having even a single part replaced. He waited patiently to check if everything going fine for another 45 minutes Thank you for your service, keep up the good work."

FAQs for water heater repair or service projects in Princeton, NJ

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.
