"Had a 5-hour window to deal with. Plumber was very friendly. Cost was ridiculously high with a number just thrown out there for the cost. No breakdown of charges. Turns out it didn’t fix the issue, so back to square one."

"Our water heater broke and my neighbor recommended Habitat Heroes. They came the same day, gave a great estimate and had a brand new water heater installed the next afternoon. Very nice work, cleaned up after themselves, didn't make a huge mess. Everything was perfect. Highly recommend. I also hired them for a new bathroom that should be happening spring 2026, will send updates with pics."

FAQs for water heater repair or service projects in Harwood Heights, 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.
