"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."

"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."

"Tyco is simply the BEST. A company and people who are genuinely good. I couldn't ask for a better or more honest plumber. Tyler is fantastic, and Rich and Mike are outstanding. Seriously, they're there when you need them and you never have to worry about if they're being honest. This is a company that values their customers and the relationships built. Tyco has done multiple jobs for us. They've installed a tankless water heater, cleaned out drains, fixed faucets, installed toilets, and more. Seriously, if you are reading this, you're in need of a plumber. Stop looking and just call Tyco. You'll never have to search for a plumber again. Thank you, Tyco!!"

"Isaiah is a great professional master plumber! He found the leak, made a plan to fix it, and explained what had failed. Then he came back the following morning and upgraded, cleaned, and improved the water heater! He is kind, competent, & affordable! He's a great find if you need help."

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.
