"I sent a message to the company in the late evening regarding my broken central AC and Jason was here Tuesday morning to look at it. He tried to repair it but was not able to due to the age of the unit and the damage. We needed a new unit and he was here to put it in first thing Wednesday morning. Took him two hours and our AC was working. He was nice and professional. We felt the price was reasonable. Would use him again and recommend his business."

"I cannot highly recommend Premier Services, enough! MY 29 year old UTICA Boiler kicked the bucket, and so Boris came the very next day to give me a consultation. My gut feeling told me that they are what I required in changing my boiler. He got me a "Williamson", and the technician, Slava, Oleg, and a 3rd gentleman, were very professional, knowledgeable, & honest. They arrived on time, were very polite & clean, They explained exactly what I needed to do to maintain my boiler in great working order. There price was very reasonable, & I even took the annual maintenance agreement, so that I can have piece of mind. THEY HIT IT OUT OF THE PARK!!! I am now their NEW Client for ALL my HVAC & pluming needs. Thank you Soooo much Priemier Services. "

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