"Elie from Advent Plumbing did a great job installing my hot water heater. The installation was completed on schedule and at a reasonable cost. I would definitely hire him again for any plumbing services."

"Justin and Phil provided me with the best quote for replacing my old water heater. They even diagnosed the problem to fix the thermostat in my water heater and gave me a quote if I wanted to stick with my old water heater. I appreciate that level of transparency. I decided to replace my water heater since it was an old unit. They did a solid job replacing it. My water heater is located in my attic and they handled the job like a pro."

"I had trouble with the AC about a month after they did an annual service and replaced the capacitor. The system locked up and they came out and I watched as they pulled an obviously old, worn, and burnt, electrical part out next. They replaced that part for the cost of the part and waived the labor as it was so close to the last service. The system is old and they were finding parts that were reaching the end of their life and replacing rather than trying to sell me a whole new system but let me know they would be there if I decided I needed a new system. Fast service, pleasant and knowledgeable personnel."

"As I am writing this I realize that I am not completely satisfied with their service other than the tech was friendly and knowledgeable. Initially, I scheduled the appointment for an annual maintenance on our 3 units. On the day of the service their office called about 3 hours into the 4 hour window to inform me they needed to reschedule the appointment. The woman apologetically explained that I was the last appointment of the day, and the job ahead of me ran into a major repair that would run late into the evening. Though I had been inconvenienced by this, I understand these things happen and was still willing to give them a try. When the tech came out the following week, I walked around with him for a bit showing him where to access the units. I explained the air filters had recently been changed except for the one in the attic which he did for me using the filter I had purchased from Home Depot. When I asked him about the condensation hoses for the units in the basement he recommended I put a little bleach in the pump to keep it clean. Is not that something he should do as part of the maintenance I am paying for? I also asked him about cleaning the condenser coils on the outside units. He said he would check to see if they need it, which surprised me because that has always been standard with other companies as well. I had an appointment to go to while the tech was working. My husband was there for the rest of the service. We ended up replacing a capacitor in one of the older units, and the annual maintenance plan seemed like the most economical at $281 for 2 visits a year. But in hindsight I am wondering if it really was worth it."

"It went well! Matt and TC at Plumb Life ATL are very professional and communicative. Matt called the day before to let us know when the plumber, TC would be arriving. On the day we were scheduled, TC called an hour before he was scheduled to let us know when he'd be arriving. TC was very punctual and determined to find the source of our water leak. He removed the water heater in less than no time. Then he explained to my wife and I that he needed to cut into the wall to find the leak. He then neatly cut into the wall and found rusty nails all throughout our piping. He removed the damaged pipe and neatly installed new piping in that area. We no longer have a water leak issue thanks to TC and Matt. Matt was also very communicative from the onset to the conclusion of the work. We highly recommend their services. ⭐⭐⭐⭐⭐"

FAQs for water heater repair or service projects in Kennesaw, GA

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.
