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!"

"Finally an honest Solar company!! I went through several companies trying to get quotes for one of my properties, either they were ridiculously expensive or they didn't return my calls. A friend of mine referred me to Mega Sun and I have to say I am very pleased. Within a couple days from the initial phone call I already had an estimate and once i decided to go with them the installation was completed in one week. Its been a little over a month since they completed the install and everything is working smoothly.

I was amazed at just how great the customer service was. I just want to say thank you to the whole team who helped out, I really appreciate all your hard work. Now I know you guys are the ones to call for all future jobs."

"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."

"I'm very happy with the work that was done by Landmark construction and energy crew. At first, we met with Ron that came over and met with us about the issues that we had with our water heater and with the bills that we currently pay for electric. Ron recommended us to replace the bulky old water heater and to install a tankless system that will supply hot water immediately and with the use of less gas. We liked that idea and we decided to go for this project. Ron came over to our house with his 2 people that basically took care of all the removal and the installation of the new system. The work that they did took only 2 days from start to finish and now we have more space at the garage, and the bills are much lower than before…."

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.
