"They quoted half as much as another company yet the quality of work was excellent. Very thorough, cleaned up after themselves, polite. The only issue was limited English but that didn't really affect anything. The project was challenging and they figured it out. Will definitely use them again for future electrical work."

"Excellent experience. We had a connectivity problem with our solar panels. They responded quickly and set up an appointment right away and came when they said they would. The technician very personable. He was able to determine the problem and correct it, updated the software on our system, and explained that maintenance was not necessary. I would highly recommend this company."

"During a recent storm, the conduit pole on the side of my house snapped. I contacted Jason and sent a few photos via text. He quickly assessed the situation, knew exactly what needed to be done, and resolved the issue right away. His pricing was reasonable, and he was professional throughout the process. I would not hesitate to use his services again. I 100% recommend."
