Customers say: Quick response

"I had a brand new water heater installed 5 months ago. It began leaking on Saturday night just as I had a house full of guests staying for the weekend. Disaster! The good old boy plumber that installed it has refused to return phone calls and text messages. Gone. Didnâ t care. . So I was stuck with calling someone who I didnâ t know and get them to do a replacement on Sunday morning. Over a dozen plumbing companies declined. Fortunately I found this company. They came out Sunday morning. Removed the old 75 gallon unit under manufacture warranty and finished the job by late afternoon. ARS did a great job. Morghon Liddel was a real professional. Very neat install. So happy I selected this company. I learned my lesson about hiring a good old retired? Guy, never again. I am very satisfied with ARSrescue"

"Excellent - We wanted to change our AC/Gas furnace system to a heat pump system and decided to use Tarpy. They provided a very comprehensive review of our needs, and spent additional time with me on the phone to help me choose the best and the most cost effective system for installation. Chris and David arrived on time and were very efficient with removal of the old system and installation of the new. They also corrected a couple of errors due to the previous installation (correcting bad welding on the Freon line, and installing a correct condensate discharge). Chris and David clean up the work area and answered any of my questions before they left. The system has been working great. Thanks Chris and David, and Tarpy!"

"They initially re-plumbed our entire house years ago so we are still under a service contract with them. They do excellent work. We have had no problems with them. They were very professional. There were only about two of them here at a time and they come do whatever they have to do and then, the construction crew came in after them and did what they had to do. We are very pleased with them. A lot of companies would not work with construction crews that way, but they do."

"It’s been a while that I wanted to have a company that can come over and check the house for any problems that increased my monthly bills and to fix them at a normal price. I came across this company and I scheduled a meeting with Ezra and Charlie to come over and see/check. Ezra and Charlie checked the house for more than 2 hours and they found out that some of the windows were old and needed to be replaced with new ones. In addition to that, they recommended me to remove the water heater and to install a tankless system that will provide me with hot water only when I need and by having that, my bills will be reduced.The Quote that I got from him was good enough (to my opinion) and I retained them for the job. The work that they did proved to be good one and I see that in my monthly bills. It was a 2 weeks work and I am completely happy with my decision to hire them."

FAQs for water heater repair or service projects in Descanso, CA

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.
