Recommended Customer Reviews

JMC is an excellent company with great owners and experienced employees. I needed electrical installed for a hot tub and they were recommended. Jon came out the next day and did a very good job explaining the process and the duration. I explained the hot tub was a surprise for my wife and he ensured it would be done the same day and he would stay to make sure it was up and running by the end of the day before she got home. After I received their detailed quote sent a few hours later, I went with them.
The day came for the hot tub install and the hot tub company was short workers, so Jon and two of his employees helped unload it and get it to it's desired location. Just so happens I misjudged the level of the foundation for it per the hot tub company rep, and it was recommended I get it fixed before filling it. Jon called a contractor who gave me a quote, but in the meantime his crew knocked out the electrical install within a few hours. The contractor was available that day and came out a few hours later. They fixed the problem in a couple hours, but by that time it was already 5 PM. Jon personally came back to the house to complete the rest of the install and get the tub up and running before my wife came home, so the surprise wouldn't be ruined. I let him know he could leave, but he was intent in getting it filled up, primed and running, which he did. He was finally able to get away around 6 PM.
Jon and his team went above and beyond when they could've walked away and finished another day being it was my mistake. Thank you JMC and crew for your dedication and professionalism, it meant a lot to my wife and I, she loves it!

Excellent service from JMC.
I got a referred from Vhet at Hot tub Spas to JMC for the installation of the spa.
Jon came out in advance to check the location of the electrical and give few options. We agreed on the most logical , less disruptive way to install, he drop off the electrical conduits so we can get the place ready for the spa and electrical, he coordinates with us in getting the pad ready, coordinates his installation crews with the spa delivery on the same day.
Hector and Alex was great. They did a thorough , clean and neat job, patiently explain what, where ,and how he was going to install the electrical.
I would highly recommend JMC Electrical service.

Amazing electricians! We hired JMC to connect a new hot tub to an existing circuit. They scheduled around the hot tub delivery, making sure we wouldn't have to wait an extra day to get our spa up and running. We also hired the to run another indoor outlet and to do some miscellaneous troubleshooting. Jon, Hector, and Alfredo were consistently punctual, professional, and conscientious, and the work they did was first-rate. We felt very comfortable with them, and they took the time to answer questions and accommodate our needs. They really went above and beyond, and I would not hesitate to hire them again.

We hired JMC as part of a spa installation. For the spa, they did a thorough advance review of the property and electrical needs; they didn't try to upsell us on a new electrical box for the house (which another electrician had said was absolutely necessary), and explained why it wasn't necessary. They coordinated on spa delivery so they could ensure it was fully operational before they left that day.
We also asked that they correct some issues arising from some other electrical work another electrician had done some time in the past. JMC was incredibly responsive, helpful, and straightforward throughout. Not only were they on-time, but they actually responded to a couple questions (that turned out not to be electrical issues) on a weekend. The price was surprisingly reasonable -- not the cheapest out there, but we would not hire any other electrician.
Finally, these were the friendliest and most pleasant electricians we've ever worked with. You really can't go wrong with JMC. I cannot recommend them highly enough!

We worked with Jon and Alfredo to get the electrical done for our swim spa and outdoor kitchen. Jon coordinated the timing of the installs with our other contractors and even squeezed us in to accommodate us. Alfredo was outstanding at being on time and would always respond quickly when I reached out with a question. Thanks Alfredo we wouldn't hesitate to use you or recommend you again.

I had used JMC once before in an emergency situation and they were awesome. Used them for several different issues this time that had piled up over time and once again, could not be happier. Alfredo was timely, profession, friendly, thorough, used all safety precautions, explained everything that was to be done in advance and again after completion and asked my preferences where warranted. JMC will be my go to electrician from now on whether its a big job or small. Finding a contractor that you can count on in all situations can be difficult but thanks to Alfredo and JMC, that is no longer the case for us when it comes to electrical.

I interviewed 3 electricians to hook up our spa. John took the time to look at our house and layout to come up with the most reasonable way to get power out to the spa. He explained the process and his recommendation. He was always responsive when I reached out.
Alfredo came out to do the work. He arrived early, was careful when in our house, and answered all questions I had. He stayed late to make sure the spa was hooked up and running. There was one small item he promised to come and take care of the next day. He came as planned and we are all set.
I definitely recommend JMC.

I highly recommend JMC Electric! I had a hard time finding a qualified electrician that does quality work. I interviewed and received quotes from at least 6. Those that I didn't use were are questionable and flaky. Alfredo from JMC Electric came to my house to do electrical work for a hot tub. He was on time and got the job done when he said it was going to be done. They were kind and answered all questions I had and were a pleasure to work with. I highly recommend them.

We got a spa in the spring. We paid for an ungraded 60amp but they installed a 50amp and promised to come back when one was in stock. It has been 7months, and with one no show at a promised appointment, no amp. Even though it was paid for.

Alex Lopez from JMC did a great job wiring up our new hot tub. I thought we might have to run it on 110 volts for a few days at first, but Alex was here working in the morning before the Hot Springs crew arrived with the tub.
Nice, clean installation under the house to the sub panel, to which he added a couple of 20 amp breakers for future use around the deck. All in all, he was fast, friendly, and competent. Thanks!
