"I highly recommend this plumbing company! They did an excellent job in my home — very professional, punctual, and respectful. The technician explained everything clearly, fixed the problem quickly, and left the area clean. Their prices were fair, and the quality of work was outstanding. I will definitely use their services again and recommend them to anyone who needs reliable plumbing work. Thank you for such great service! ⭐️🔧💧"

"First - hire Keith & I hope you read the rest. If you live in the Keys, you know contacting a plumber on the weekend is almost impossible. I had a water leak that was turning into a serious situation. He came over and stopped it quickly. Once he figured out what was causing it we agreed to have the shower plumbing repaired and the fixtures replaced. Then, because Home Depot would not install the new dishwasher because of old plumbing, Keith suggested he could do it. On the same day, he fixed the shower, repaired the sink plumbing, installed the dishwasher along with a new faucet & disposal. Keep in mind that this is an old house with old plumbing, appliances, etc. Keith was incredible. Incredibly competent and great to work with. If I were you - I'd choose him first. Thanks for everything Keith!"

"Both the visit and repairs went really well. Lazaro came and repaired both hose bibs and allowed me to inspect his repairs and test before leaving. I was actually surprised I was scheduled the following morning; to me that was a big plus. Would definitely recommend."

"Amazing technical expertise and physical strength displayed by Mr. Hall who got the water heater to second floor by himself and safely installed my brand new unit. He's also maintained my AC for the last 7 years and recently replaced my thermostat. He is also knowledgeable and able to make electrical repairs and wiring. He is also an honest person who will advise you accordingly."

"Brandon Bing and Steve Lorenz are owner-operators and I found both of them to be skilled in their trade, honest and hardworking The installation of the water heater and solar panels went well and any bumps were smoothed out. I am initially disappointed in the Solar array's electric impact but I have a few trees that I need to take out and I still need to get my FPL net metering installed. At times I am producing more than what I consume so until I get net metering installed I cannot capitalize on overproduction. These comments are in no way a reflection on All American Solar for their work ethic or products. In fact, the array is expandable so that I can add more panels in the future. The Solar hot water heater is fantastic and has saved me about $60 per month off my electric bill. I would gladly recommend All American Solar for your solar panels or a solar hot water project and I would hire them again."

FAQs for water heater repair or service projects in Key West, FL

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.
