"Excellent...we had some additional issues related to water pressure regulator, piping, etc. The situation happened on the weekend and we had hot water running by Monday afternoon. An EXTREMELY short time compared to our last water heater issue. Highly recommend Heart and will use them from now on."

"We had the unfortunate incident of having a water heater break down in the winter. Unlike other places that were quick to diagnose that I just needed a new water heater just by talking to me over the phone, Jim Needham Plumbing sent in a professional. Tyson, the tech that was sent out, was by far the definition of professional. Iâ ve had techs come out that seemed professional but then just left more of a mess than when they came in. Tyson diagnosed the issues and not only gave me multiple scenarios I could choose from but made me comfortable in my decision. As soon as I made a decision and asked about next steps, he not only told me every step but accurately broke it down to how much time it would take. I was worried because if he missed his projected window I would not make my virtual meeting for work. He not only completed on time, he explained everything to my fiancée and she noted how meticulous and careful he was in our house and with the disposal of the old water heater plus the clean installation of the new one. In our next home project you bet we will be calling back to have them continue their level of experience and professionalism."

"They installed a hot water heater in less than optimal conditions (a water closet with outdoor access only) on a very cold windy day. The plumbers were quick and efficient. They exhibited a craftmanship we seem to be losing these days."

"Service went very well. Dan called approximately one hour before his arrival to let us know his ETA. Upon arrival, we discussed the issue and he inspected our inside and outside unit. He was able to diagnose the issue fairly quickly and went to work on fixing it. He explained the repairs before completing, including the cost. He also left us with recommendations for the future. Overall, the visit lasted about 90 minutes and the repair cost was (luckily) minimal. Our home was back to feeling cool within 36 hours (after 48 hours of no relief from the heat). Based on this experience, we will certainly use All Weather Heating & Cooling for our future HVAC needs.  <br />"

"Tony did a great job replacing my broken 50 gallon self venting hot water heater. It is in a difficult space to maneuver getting the old one out and the new one in. He did a great job updating what needed to be done (in my old 1910 home so there is always something!) and I feel very confident in their work. Limelight is my go to place and am so glad I found them!"

"Keith was excellent from his first visit to explain what needed to be done on the kitchen drain. Afterwards, I requested a new water heater to be installed. Both were done this morning in a timely manner. Keith is very competent, takes the time to explain everything, and did an excellent job. I also was extremely thankful to Keith this morning as he identified a gas leak that I otherwise would not have known about. Because of Keith I was able to call the gas company and they came out within the hour to address the problem. I highly recommend Keith to anyone needing services. And, if I have any future issues, Keith will be the first person that I will call. He is a wonderful person, and he did an excellent job for me! Thank you Keith!!!"

FAQs for water heater repair or service projects in Boulder, CO

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.
