"The service team kept in touch regarding arrival time so I knew what to expect. The technician Jonathan worked quickly and efficiently. He had a water heater on the truck and was able to complete the work same day, unlike 2 other companies I got quotes from. While I was shocked at what water heaters cost these days, High 5's price was very competitive with the other bids."

"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."

"My air conditioner was tripping a breaker. I thought it was the breaker, but it turned out the water was banking up in my furnace and tripping the breaker. The guy who worked on the air conditioner didn't try to sell me a new one, he just fixed the problem. The last guy who serviced the system didn't do much except for tell me I should buy a new air conditioner in the next few years. I don't even think the cleaned off the conditioning unit outside. I was very happy with Applewood."

"Steve came out to diagnose an outlet/breaker issue. Price to diagnose was really high. I was really shocked (pun intended) to find out the price to replace a fried GFI. However, Steve worked with me on the price, and I ended up getting a one year maintenance plan. Great customer service provided by Steve and the office staff, and the issue was solved quickly. I will have them out to do some more electrical projects around the house. I also plan on having the heating and air group out to service the furnace and air conditioner. Be prepared to spend more for their services, but know it will be a job well done."

"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."

FAQs for water heater repair or service projects in Denver, 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.
