"The majority of the time I contacted this company the people answering the phone were very friendly and courteous. On the day of my install, the last person I spoke to was not as nice. Regardless, that didn’t give me a bad impression of the company as a whole. Chad, the service technician, was awesome. He took the time to inform me of my options on repairing or replacing my hot water heater without attempting to sway my decision. Once installed, he made sure that the water was flowing normally from every faucet. He then informed me of everything he did during the install. Chad definitely gets an A in customer service and experience."

"On November 15th Chicago was hit with some extreme wind gusts that caused my water heater pilot light to extinguish. I thought this was a simple reset, but the problem was more complicated. I learned the electrode was defective. Had I undertaken this project as a DIY, I would have spent more time than I would have cared to try to figure out why I could not get a flame for my water heater. I was smart to call Four Seasons. My technician figured out the problem quickly. There are times when calling a professional makes sense. I am not an expert on water heaters outside of knowing how to turn it on, clean it periodically, and knowing when I need a new one. Thank you Four Seasons for responding quickly and bringing me hot water."

"Andrey was very knowledgeable and took the time to explain what was happening and how to fix it going forward. Also offered helpful advice for an old water heater (not what the initial call was regarding.) I would definitely use SAV again."

"I was very pleased with all the work Joe did at my Mom's house and mine in Cary. At my Mom's he put in a new utility sink and repaired it and also repaired a significant leak downline from a toilet. When I saw the quality of his work I hired him to work at my house. There he removed and replaced a hot water heater and repaired a big leak in my utility sink and replaced the faucet. With the water heater he had to remove the black pipe to remove the heater then repipe after. After he was done both houses were cleaner in the areas he worked . I would hire him again if I need any plumbing done in the future."

FAQs for water heater repair or service projects in Mundelein, IL

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.
