  • I needed help unclogging my shower drainage. The technician, Mr. Raul De La Luz was very polite, professional, and efficient. He took care of the issue in less than half hour. And when he was done, the area was clean and back to the way it was before he came. I am very satisfied with his service. M. Tran|Irvine, CA

  • We are very satisfied with their service. Erick is very easy to deal with. He constantly update us regarding his arrival time. We had a floor leak to which he is supposed to detect the slab leak. At the moment he arrived at our place, my husband already found the leak so we don't need his services. We are willing to pay Erick a dispatch fee but he said don't worry about it. He also gave us some advises about how to deal with our leaks. He is very professional. Will definitely use Dial One Soneshine again. Han C.

  • Having moved to the OC recently, we were in need of an HVAC electrician. We found Dial One Sonshine online and called to set up an appointment. Dustin arrived on time and proceeded to replace our old thermostat with a new one. Once it was installed, he checked to see that everything (heat, A/C, fan only) worked properly. We were so happy with the results that we signed up for an annual checkup for the furnace (fall) and air conditioner (spring). Count us among the many satisfied customers Chuck R.

  • John was amazing and totally helped us out. Nicole was curtious when I called to make the appointment and very helpful. Melinda called us 30 minutes before John showed up, letting us know he was on his way. Perfect service! Michelle L
