Recommended Customer Reviews

Chris is a great guy. I called around and not only did he give me the best quote but he gave me a lot of great advice. He responds via text immediately and he has an immense fund of knowledge. We have an old water tank inside a very awkward spot that I thought was going to be impossible to remove but Chris did it all by himself. Given the scope of the work and he completed it very quickly. He even showed me how to get a rebate from the utilities company. I definitely enjoyed working with him and recommend him to anyone who needs work on their water tanks!

Wow. These guys are great! They were fast, affordable and professional. They installed our tankless water heater and it works like a dream!!! 20 min hot showers!! Chris is very knowledgeable and helpful. They also back all of their work with a warranty. Old school pride in their work, you can't find that anymore.

super responsive and helpful in solving issues with my water heater. Spent a lot of time working with me to diagnose the problem and find the right solution.
Puts you first, which is really refreshing to see! I would definitely recommend for all your water heater needs.

I posted a problem with my tankless water heater on the Nextdoor App and very shortly afterward, Chris responded that he would troubleshoot with me over the phone, so I sent him photos of my heater and he told me some simple instructions about how to reset it and it works just fine now. I had called two plumbers and both did not suggest those things and would have charged me for service calls and more, so I greatly appreciate what he did for me at no charge! I will recommend his service and use this company for future needs. Not all plumbers know about tankless water heaters.

I called there Technician they respond very quickly replaced my tankless water heater working so great very professional people. Thank you for your service.

I decided to upgrade to a tankless water heater when my previous unit started to show signs of fatigue. A friend recommended Chris. I placed my initial call in the afternoon and he was able to come out the next morning. I was surprised by how affordable a tankless unit would be (even with the conversion from a standard unit). I scheduled the install. Chris was very clean, polite, and professional; I highly recommend!!

Santa Clarita Tankless Water Heaters was fantastic! The owner was very responsive, knowledgeable, and effective. I'll definitely call him again if I ever need help with my water heater. You're in great hands with this company.
