"Heart contacted me immediately - Even though it was on Easter Sunday. The technician performed the repairs satisfactorily. The only recommendation I would add is that I received 2 text messages, saying that two different technicians had been assigned this job, and they were both on the way. Plus, it was a little pricy for the parts and amount of time taken to complete the job."

"Able to replace my water heater the same day - on a Saturday. Timely, courteous, and knowledgeable. Took old water heater away and left no trash behind. Brought the equipment up to code and replaced lines / parts as needed. Jason was great. I will call Big Apple again."

"Curtis diagnosed the problem and fixed and verified the furnace is working correctly. He did this in just a little more than 30 minutes. His 18 years of experience was well worth it. He took apart the gas valve area and found between the gas valve and the orifice to the burner had a spider web obstructing the gas flow. The furnace works well now. Curtis was very professional and honest. Thank you, Curtis, for a great job. I had another company check the furnace last week, but the tech they sent did not have the experience to correctly diagnose the problem."

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.
