"The installation technician, Danny, showed up on time and was extremely professional and friendly. He installed a reverse osmosis system under the kitchen sink with a brushed nickel faucet beautifully mounted on our granite counter top, as well as a whole house water filter and softening system in the garage. His workmanship was terrific and the system works great, we couldn't be happier!"

"I had a leaking water softener that was leaking into my wall. California Plumbing was able to come out quickly and assess the issue. They helped me get a restoration company to help with the water damage. We ended up needing to replace the water softener but they made the process as smooth as possible!"

"Gus at Pro Bright went above and beyond on a Sunday to detect and repair our master bedroom ceiling leak. With water to the house turned off at the street we were desperate to find a contractor who could respond right away. Other contractors offered appointments Monday or Tuesday. Gus responded that he could be here in 2 hours to repair the leaking pipe, but could have Jeff, his water mitigation project manager here within 30 minutes to assess the water damage. These guys were both so professional. They shared the process, timeline and costs, and were prepared to start right away. They promptly moved my disabled husband and his adjustable bed to another room away from the work area assuring his comfort and safety. Gus repaired the overhead leak and turned the water back on. Jeff scheduled the water mitigation process to begin first thing Monday morning. We are especially grateful for the kindness these 2 professionals showed us in our time of need."

"The tech was professional and arrived on time. The general routine cleaning went fine. However, the troubleshooting did not resolve the issue. He did notice the unit leaning a bit and straightened it out, but a couple of months later during another hot spell the unit was leaking again. I called them and they sent the field manager who cut and replaced a very crooked condensate line and it appeared all was resolved. Fast forward 10 months of rare usage: after 3 days in a hot spell - the leak reappeared. I shut off the a/c and waited for a good 5 months before calling a different plumber who blasted out the main condensate and the secondary line, and tested it by running a gallon of water through the line. I don't believe the line was sufficiently cleared if at all, the first two visits with Carini. This seems like a pretty routine issue with condensate lines so I'm disappointed that it would have been either overlooked or insufficiently cleared out.

"Your guys CJ & Andrew were awesome! They did such a nice clean looking job! Super professional and very informative. They walked me through setting up the app for the whole house water shut off valve they installed and now I get a reduced rate on my homeowners insurance. They also found that my water pressure reducing valve had failed and replaced that at the same time. Couldn’t be more happy with the job they did."
