Went out of their way to make the experience positive. When the landscaper needed power and was about to go get his generator, provided a temporary outlet and saved them a couple of hours.

 Trustindex verifies that the original source of the review is Google. William was very easy to work with. I was able to get a quote and set up an appointment very quickly and easily. I was hoping for an earlier appointment time and he was able to make it happen! He was very punctual and kept me notified of when he would arrive. He did a great job installing our Tesla charger. He installed it beautifully and made sure he didn’t leave until we were set up correctly. We’ve already recommended him to our neighbor and would continue to use him whenever needed!

 Trustindex verifies that the original source of the review is Google. I had William from EPX install a Span panel in my home to compliment my Freedom Solar and Tesla Power Walls and to provide whole home surge and lightening protection. His technicians put in a full day plus over time to make sure everything was properly working before they left. When the Span app stopped working as expected a week or so later, I sent a text to William and William personally put in a service request for me at Span. Sure enough, the app was functioning as expected very soon after I contacted him. I am very happy with EPX and William is a pleasure to work with. Thank you!!

 Trustindex verifies that the original source of the review is Google. Team came out to install a SPAN panel and impressed me beyond words. Excellent communication, established clear expectations, worked diligently and effectively to complete the project in the given time.

They also made sure the right breakers were installed on the right runs for critical systems (I.e. AFCI for bathrooms and the kitchen runs near to water). Took the time to confirm our power and grounds were up to current compliance standards. (Which we did a few years ago after the meter box replaced because of arcing)

I’m so delighted to know that this is now in place, rather than a power breaker box older than me. Would highly recommend them for any electrical projects.

 Trustindex verifies that the original source of the review is Google. Willam and the EPX team as well as the teams with KPost did FANTASTIC Work on my Tesla Solar Roof, Powerwalls, and several projects inside ranging from Low Voltage pulls to a 30amp 240 additions for my in house servers.  These guys were incredible!  Every day ended with a clean-up leaving things consistently better than they started!  Several of my neighbors commented that they loved just sitting out and watching the progress, that they’d not seen any teams so organized and professional. I don’t give praise lightly and I’m incredibly driven when it comes to my tech and electronics (and in proxy electrical provisioning).  You absolutely, will NOT find better than these guys.  If you get the chance to work with William, you will understand just what +2 service is (thats right, +1 white glove has nothing on these guys).  William and team - thank you SOOOOO much for everything, you raised the bar so high that I’ll never be able to work with anyone else again!  You have earned my every project and reference!

Bottom-line, I don’t care who else you’ve found or at what price, these guys are the best at any price and you are not rolling the dice with uncertainty - if they even provide you with half the experience I had you are going to be raving fans too!

“William is simply the best. My wife and I have been undertaking a remodel that has taken a year and a half to complete and we have had many highs and lows. But out of the highs one stands out, and that was William. He is professional, courteous, respectful, fair, and fun to boot. He rewired our entire house and did an amazing job. Our jobsite is a couple hours away from where William lives but he was willing to drive several hours to and from to honor a small warranty issue (a small breaker was a lemon, nothing related to workmanship) and did so with a smile. To this day I can call him up if I need to troubleshoot something and he remembers exactly how he wired my entire house from memory and is always willing to walk me through anything. Again, simply the best. Though we probably won’t go through such an extensive remodel ever again, if we do, the first person we are calling is William.”
