"Just 2 days before closing on the sale of our home the water heater quit working! I tried to get it going again but the pilot wouldn't stay lit, that morning I called Tiger Services and had an appointment set immediately for that afternoon. On arrival the technician gave the water heater a quick look, tried to light the pilot and immediately determined that the burner had gotten wet and the whole unit had to be replaced, I was rather devastated with this happening so close to new owners taking over. They provided me with immediate ability to change the whole unit out without having to wait any time at all (was afraid it would be a day or so), and also hauled away the old water heater. The new one worked fine for my last day in the house, and I assume it is going just a well for the new owners. Tiger services also gave me a bit of a discount for a service warranty due to the situation. The technicians also took care to clean any messes, some water spilled out and he immediately shop-vac'd it up, and well as wore shoe coverings and hauled away all the little bits of other trash in addition to the old unit  as I mentioned earlier.

"This was the first company I selected after becoming familiar with HomeAdvisor. Terry, the plumber, contacted me very soon after my submission and came to look at our problem the next day. He gave us a very affordable quote and came back the next day to do the repair. This is another HomeAdvisor business that I would hire again in the future and recommend to my family and friends."

"When my house was built 25 years ago the wrong gas line, type M was installed.  Earlier this year me and other neighbors were informed by letter from our county that when we had a new gas water heater installed we would also have to update the gas line to code.   Jeremiah had to replace the copper line with 'iron' lines, he did a great job!!  He is very knowledgeable, friendly and helpful
with questions I ask him.  When I need a new air conditioning and heating unit Froggy's Heating & Air will be the first company I will contact."

"Our water heater went out the other night. I called and explained what was going on and they assured me that someone will be out as soon as possible.  A bit later the technician came to the house ,first he greeted us then he put on his shoe covers before coming into the house.  When I showed the technician the problem he was very patient in explaining to me what all needed to be done and he answered all my questions in a way that i could understand. I was impressed with his knowledge of the business but more impressed with his people skills. That night was our first time to call a plumber and if we ever need one again we will definitely call them!"

"We had a very good experience with our Bathroom Remodel. Basically, the bathroom was gutted. Dylan was the representative that helped us through the design process. He brought all samples to our home to make choices. He was patient, knowledgeable, and overall, very pleasant to work with. Ben and Kellan performed the work on the project. They were very professional, and extremely hard working! They literally took lunch breaks and other than that worked the entire day without breaking. They were quiet as can be, they didn't have any music playing or even receive private phone calls. They cleaned up after themselves each evening before they left. Extremely pleasant to have in our home. They kept us informed along the way and paid attention to detail. We couldn't be happier with the end results, job well done. I would definitely recommend them or use them again. Steve & Debbie K."

"I hired American Appliance Repair Services to repair a GE Profile electric clothes dryer. I've used GE to repair other Profile appliances with mixed results and a high price. American Appliance Repair scheduled service two days after initial contact, technicians arrived on time, problem quickly diagnosed and after a quick trip to a warehouse to obtain the defective part the dryer was repaired. The charge was reasonable. I am completely satisfied with the service they provided."

FAQs for water heater repair or service projects in O Fallon, 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.
