    And my ring nice and straight
    Esmeralda R.

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

    This is our home in South Corona, with working lights around the outside  after 5 years of nighttime darkness!!!

    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, Wendy in South Corona (I have lights for the New Year).

    Installation of NEMA 14-50 outlet for Tesla EV charging
    Ricky S.

    Mr Kool installed a NEMA 14-50 outlet for Tesla Model 3 mobile charger. For starters, he did this job for the cheapest price (I got quotes from 8-10 electricians on Yelp). Setting up appointment was easy, he showed up on time.... Very friendly, courteous & knows what he is doing ...... Finished the job in the time he quoted & cleaned up the area after he finished installing.....HIGHLY RECOMMENDED.... 5 STARS !!!

    They installed this Senville LETO Series Mini Split Air Conditioner Heat Pump.

The finished result looks even better than I expected. Shannon even helped me set up an Alexa routine so I can say "movie night" and the lights automatically adjust. Very professional and easy to work with. I would definitely hire him again!!

    We hired this electrician for several items during our move-in, including outlet work, lighting,…read moreand ethernet/WAP setup. Unfortunately, the overall experience was disappointing. The biggest issue was lack of care for our home. No drop cloths were used, debris was left throughout the house, and cleanup was minimal. An outdoor trash can was brought inside and rolled across hardwood floors. Upstairs, dust and debris were left on carpet, in closets, and on bathroom floors. The job sites were consistently left messy at the end of each day. There were also multiple incomplete or questionable aspects of the work. The ethernet line in the bonus room was charged as a full install ($650), but the line was already present--this was only acknowledged after I raised it, and the explanation given was that the charge was for "testing." The WAP was not properly connected, and some outlets were left unfinished/dangling. For chandelier installs, drywall screws were used in base plates, which is not appropriate for final installation. Scheduling and communication were also problematic. On the day work was supposed to be completed (which required me to rearrange my work schedule, which he knew), the appointment was canceled that morning. A new availability was offered that conflicted with my schedule, despite that same day previously being unavailable. When I requested a partial refund for incomplete work, the response was that additional unbilled items offset the charges. That was not discussed in advance, and does not address the core concerns regarding workmanship, cleanliness, and professionalism. We ultimately hired another electrician to complete and correct the work so we could move in on time. While the cost itself was not the primary issue, the lack of attention to detail, respect for the home, and follow-through made this a poor experience overall. This was not the first time I remodeled a home, so I understand the unexpected, but given the overall experience being extremely substandard, I would not recommend this electrician.
