"Greg was wonderful! He inspected our outlet, determined the issue and repaired it. He also took the time to explain the units in our circuit box and the wall outlet. I felt very confident in his work and would absolutely hire him again. I am so glad we found Streamline Services on Angie’s List."

"This heating and air conditioning company is superior and the gold standard by which others should be assessed! In my opinion, their professionalism, customer service, unquestionable expertise, clear communication, fair (perhaps more than fair) pricing establishes Delta Heating & Cooling at the top of the local industry. I met with the owner to discuss the best system for my home with no attempt to up-sell, he answered all my questions without rushing me, and fully explained the Delta installation process, which was flawless. I could not find anything negative anywhere about Delta. Although I did get other estimates, such was pointless since none could beat their price. In summary, you will not be disappointed with Delta!"

"Very satisfied with the outcome. The house was not occupied while this work was being done, so I was not present during much of the work to observe the installation of system & ductwork, but it worked beautifully once we moved in and began to use it, a turnkey experience. Twice since then we've had questions (e.g., Can we move the ductwork in one part of the attic to accommodate new attic stairs?), and both times they were very responsive and came out at no charge to me, despite the fact that the work was done over a year ago. I've interacted with both Mike (the owner) and with one of his technicians, and have been very satisfied with the level of customer care I've received. I will use them in the future for our heating & A/C needs.

"Excellent,prompt,courteous and professional service all the way from initial contact from ARS quickly reaching out to me to set up an appointment to the work done by their technician. He arrived on time, was friendly, professional and proved to be very knowledgeable and skilled in his profession. He quickly identified the problem with my water heater and had it fixed in a short amount of time. I am very impressed with ARS and will use their services again in the future for any plumbing needs. I highly recommend ARS."

FAQs for water heater repair or service projects in Knightdale, NC

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.
