Recommended Customer Reviews

Small job, quickly taken care of.
I'm impressed with how quickly Gentec returned my call, made an appointment, and took care of the loose wiring. The problem was minor and they treated it as such, not turning a minor job into a major re-wiring project. I appreciate their honesty, work ethic, and competitive prices. I'll definitely use them if I need an electrician in the future.

We needed a lot of electrical work done to our house. We found Gentec Services on Yelp and called them for an estimate. They sent AL M. to our house. We felt much more comfortable with Gentec than with the other companies we called, so we booked them.
AL was in charge and two workers came with him. AL was really nice and very professional!
Some of the work they did included installing; a new main panel (including moving the location), a new sub panel, arc fault breakers, and 3 new exterior lights (including compliant wiring). They also ran dedicated circuits to the washing machine & dryer and grounded a couple of outlets.
We are really happy with the work they did and are confident that they did everything to code as requested. Also, we want to emphasize that AL M. and his crew were extremely knowledgeable & professional and they did an fantastic job! AL M. deserves a bonus! If we need more work done in the further, we will request AL M.
Overall grade: A

With our furnace out and the winter cold creeping in, GENTEC had a technician out FAST, who quickly pinned the problem down to a faulty fuse. No upsell and no hidden fees, just a few observations and suggestions for future upkeep and maintenance. And it's WARM in the house again, which makes us all extremely happy! I will use GENTEC again in a heartbeat.

Recently used Chad Supnet from Gentec Services to position two TV wires/cables in the wall. He did an amazingly seamless job. He was pleasant, professional and followed up re arrival time for his two visits. Based on his expertise I would highly recommend this company.

I worked for Gentec for around 3 months. Although I no longer work for them I must say that they are a very professional, honest and do outstanding work. Joe is a class act. He treated me with the utmost respect and took care of me as an employee. I would highly recommend them for your electrical needs. The up- front pricing is awesome and Joe takes the time to train each employee to a standard that is second to none. Hire them- you won't be disappointed.

We found GENTEC through Angie's List and they were just great. We had LED recessed lighting installed in one room and a fan in another plus a ceiling repair and other electrical updates, switches, dimmers et al. They were clean, very professional, on time and thorough.
Al Moreno a master electrician had very useful suggestions for the recessed lighting and worked with us to accomplish everything we wanted. Experience matters!
We highly recommend this company.

These guys are awesome. Installed everything I needed and presented clear options. Outstanding value. I got a gold star from AT&T because the wiring was done so well. I would recommend to anyone.

Been doing some fixing/upgrading in my house lately. This outfit has to be one of the most professional and pleasant experiences I have every had in the world of contractors.
A couple months ago I had Gentec install 3 ventilation/light fans in 3 bathrooms. The electrician who came was on time, pleasant, courteous , efficient, cleaned up job site well. I also bought the fans from them and I thought I got a reasonable price based on my looking around before hand.
Were they super cheap? No. They were reasonable and delivered high quality and no headaches.

Just had a ceiling fan installed and it looks great! Jaremy came out and gave me an estimate and was great about calling ahead if he was running behind. He warned me when he did the estimate, since there is no access above the ceiling where I wanted the fan there was a possibility they'd had to put a couple holes in the ceiling to do the wiring. That they'd patch it up but we would of course have to paint/texture ourselves or get that done. To my delight he was able to get the wire through without having to do that - and I could tell that was no easy task! I am thrilled! Great service - I would definitely recommend them.

I called this company as it appeared in a booklet indicated of very high quality service. I wanted a video equipment installation. A person came out and he took my $60 or so and it took several weeks to get a quote for what I wanted. The quote was for approx. $5000. So, naturally, I wanted to know exactly what I was getting for this amount. I never got a response to my request !! I sent several emails. I ended up going elsewhere.
UPDATE: Owner contacted me, verified my complaint and provided immediate refund ! This company listens to your feedback. Everyone deserves a second chance , don't you think so?
