“Sergei came on time, diagnosed and fixed the issue in lightening speed, and did everything in a friendly manner. Thank you!“

“Very impressed with professionalism and responsiveness - there was not a moment where we were left in the dark about what to expect next. We had a pinhole leak during afterhours and contacted several plumbers who dragged their feet getting back to us. Orange Coast sensed our urgency and connected us with Bobby help us shut off the water in our unit. Scheduling was easy and they contacted us when they had a last minute cancellation and could fit us into their schedule for a next day inspection and repair from Colton. Colton was able to identify the source of the leak with just his ear and some moisture reading tools, the repair was done in less than an hour.“

“Regarding my TESLA Solar Batteries, 1st phone contact was good. But Semper has not started the necessary repairs yet. I am a past and present customer of Semper Solaris… my past experience has been more than excellent. Even referred them to my daughter who also installed solar panels… I have no concerns with the battery issue and expect a complete and satisfactory service…“
