Average 5-star reviews

Couldn’t say enough good things about Daniel and Ultimate Electrical. He answered immediately, offered a same-day visit, and texted a clear diagnosis and plan. He sourced parts right away and, as promised, finished the repair the next day and emailed the invoice. Professional, responsive, and confident—he turned a worrisome issue into a smooth fix. Highly recommend for any electrical need.

Best electric company in Kona! I’m absolutely blown away by the level of professionalism and dedication Ultimate Electric provided me on many of my renovation projects. 100% satisfied with Daniel and his crew. He is always on time every time, consistently fast, easy to deal with and fairly affordable. I highly recommend!

Daniel and Michael came to estimate, gave me a date for work (within 1 week), came the day stated and completed the work very efficiently. Very professional. Would use them again for electrical.

By Richard W.

I have had them out twice now, and Daniel did an excellent job in both cases, correcting a previous installation of a car charger breaker/receptacle (by another company) that was shabby.

By Rune Dahl

I tried calling two other electricians to check a faulty power outlet, but neither could commit to a particular time or even call me back. Ultimate Electrical came out the same day to replace the plug without any issues. I HIGHLY recommend them for any electrical needs.

Daniel really helped us out with guests in the unit and the mood lighting going haywire. While he was at it he fixed the fan and lighting on our Viking Grill Hood. All without inconvenience to the guests! Thanks!
