Recommended Customer Reviews

I needed an electrician for an EV charger, so I called around, and this place had awesome reviews--they came out that same day! They did a great job and were very affordable than the others. I'd totally recommend them to everyone and will use them for aby future electrical work.

JR came out promptly and helped me get a Nema 14-50 outlet installed in my garage for an EV. He was able to explain everything clearly and do a clean install. Recommend JR for your electric needs

Today is New Year's Eve. I called to get an estimate to repair the lights around my home. 5 years ago when they stopped working, an electrician came and quoted $2 ,000 dollars to make the repairs. Ouch!!! Today, I decided to bite the bullet and pay the cost. When I called, I was prepared for an after New Year's appointment, but Jr. said he could come today and no charge to tell me what was wrong. Well an hour and a half later and 1700 dollars less than expected, I have outside lights for New Year's. And to top it off, he is was extremely honest, no charge to tell me one of my posts were not working because I had the wrong voltage bulb. Of course Jr. showed me the right one to order. I will be calling Jr. for all my electrical needs. I have already called all my friends to tell them of the great service that I received. Happy New Year's, may God bless your company with a prosperous year.
I can't thank you enough,

The Quality of work was at point. Quick turnaround time and amazing customer service. Happy with the whole process

JR is great! I reached out about an EV charger this morning and he responded immediately, showed up in the evening, and finished the job same day. He quoted me a great price and finished the job in two hours. He even coached me through the proper way to do the job so I got to feel like an apprentice for a couple hours. Highly recommend.

I needed two outlets for our outside patio. I received a quick response from Electrical Services by Mr. Kool. His professionalism and quality of work meeting NEC's met our expectations. The work was done after 48 hours of requesting a quote! I recommend this business if you're looking for electrical work.

""Professional, punctual, and reliable service! Highly recommend Mister Kool for all your electrical needs.""

My tech, Junior, was great and he did an excellent job installing my Nema 14-50 plug. He went above and beyond and explained things to me so it was easy to understand. I would definitely hire them again and will do so as I need a flood-cam installed.

Impressed with how clean he worked, very proffessional.
No messes left behind, ontime will recommend.

I highly recommend electrical services by Mr Kool. He's a real professional, whatever electrical project you want to complete in your home or business he's the man for the job. He also provides reasonable prices, again he's the man for any electrical jobs you need.
