"We had a problem with our water heater only heating half the tank. I called Precision Today and they could not have been nicer. This includes from the time I called, speaking to the woman on the phone. They sent someone out the same day. TJ was incredibly knowledgeable and professional. Turns out we needed a new water heater. He got the new one and installed it same day. This guy knows his business!! I canâ t say enough about the honest, professional work we received. Weâ ve used other companies that didnâ t come close to Precision. So grateful, thank you!"

"J&S provided great service during the installation of my new water heater. The process for hiring was transparent and communicative. I was quoted a very competitive price and they included all the details necessary. They were on-time for the day-off appointment and were able to remove my old heater and install the new one pretty quickly. Also, I'm on the 4th floor with no elevator. So, it was also a physical challenge to complete this job. Great service, would definitely recommend."

"Tech performed service per protocols. He informed me that the water line to the attached humidifier was brittle and needed to be replaced. This was an expensive repair but I was offered a discount. Per their points inspection, the Tech verified that there was no gas leak from my water heater. The thermostat was not inspected since it is functioning and we are observing COVID recommendations. I was given a five-hour window for the Tech to arrive. This is the longest time frame ever. I assume that the extra COVID procedures are the reason. The Tech was professional and respectful of home COVID measures."

"I called Top Tec Oct 4 to check my existing water heater. Steve came out and looked it over and gave me the bad news. My 9 year old water heater was shot. The next day, Steve removed my old water heater and installed a new Rheem water heater. I could not be more pleased with how quickly the work was completed and with Steve’s expertise!"

"Talk about above and beyond. Dorian texted me immediately and FaceTimed to instruct how to shut off the gas and water line at 8 o’clock at night. He was at my door before 8 the next morning ready to work. He had the water heater replaced and the area cleaned up before I heard from another plumber. The work was excellent and he was the most cost effective. 10/10 would use again and recommend to anyone needing his services."

"Patrick, the owner made the service call to my house in about 1/2 hour. I was alone, babysitting for my two grandchildren and very worried. I explained my problem, he told me what to look for (a water shut off valve) and asked if I could turn the water off. I told him I would try. I was frantic because with the babies, then not finding any shut off valve, water coming up from the floor, and clearing way for what I thought would be a wall tear down - Patrick and his "manager" (?) arrived. (Mind you, my family also came to help, but did not locate the shut off valve). The water pipe happened to run under my bedroom floor! Needless to say, WITHIN MINUTES the rushing water stopped. I still have water for daily household use as the problem was a broken pipe to the exterior spigot.  Patrick was soaked, yet took the time to explain to me why exactly this had happened. He encouraged me to wait until the Spring when the weather is warmer to make any changes and repairs. Patrick is professional, knowledgeable, and quite a gentleman, (despite being waterlogged) and I felt that he gave me all options for this future repair.

FAQs for water heater repair or service projects in Oak Brook, 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.
