JR has done several jobs for me including a recent one at my business. Highly recommend! He is honest and reliable! Have even gotten other quotes on multiple jobs and his has always been the best! He has gone above and beyond the electric work to help complete the whole job at hand. Thank you JR!

JR and his team are awesome! My wife and I recently moved to Corona and we needed an electrician. I had them install a coax cable for my internet, an outlet near my toilet for a bidet and a EV outlet to charge my car. There’s no job too big or small they can’t handle. JR is a very honest and professional person. His pricing is fair and the quality of his work is excellent. I look forward to using Mr. Kool for many more projects to come. If you’re looking for electrical services near or around Corona look no further. Thanks JR!

They were responsive, showed up as scheduled, and made sure the job was completed properly. We would recommend them for residential electrical needs.

We had Jr and his team install an EV outlet in our garage, and it was a job very well done. They were professional, friendly, and took the time to explain our options.

​Our installation required upgrading a circuit breaker and running heavier gauge (AWG) cables to handle the power load safely. They did a great job navigating our home’s limitations and helped us make the most informed decision for our setup. The final result is clean, professional, and works perfectly. Thanks for the great experience!

I recently used Mr. Kool Inc. for ceiling light installation and a full upgrade of my electrical panel to 200 amps, and the quality of their work was exceptional.

The service was delivered at a very fair and reasonable rate, and the results exceeded my expectations.

It's great peace of mind knowing the skilled electrical experience that Vinny leads the team with. He and his team have helped so many clients with large scale and small projects for lighting and electrical. We love their customer service, too. Go Alliance!

Absolutely horrible customer service. Answered the phone beyond rude. Unprofessional is an understatement.
And any good review is from years ago all recent are horrible. Don't waist your time!

J's electric installed some fans and outlets for me at a reasonable price. Will recommend him to friends and family and my future project's.
