Best Backup System in Chicago IL

Kent was great! He was knowledgeable, professional, on time and the final result paid was well below the estimate. This is my new go-to electrician. I am recommending this company to everyone I know.

Jaroslav was very helpful and professional. Did excellent work in a timely manner.

The electrician gave a fair price and did excellent work, and the whole experience was smooth. I highly recommend this company.

They distribute high quality products.. after sales services also very highly recommended

I was remodeling my house and needed to upgrade my electrical panel to support the new appliances. Rey came out with his team to do the job efficiently and fast, the work was completed on time. Very happy with their service. Will call them again

I have used Penco for years and have always been satisfied with their work. They maintain our generator but we also used them to install smart switches. More recently they installed lights, a new panel and electrical switches to support my small woodworking shop. Everything was completed professionally and they provided me with guidance and consultation every step of the way.

They were super friendly and knowledgeable, and even though it was a pretty big job, they made sure to explain everything clearly and make sure I understood what was going on before they started working on it.I'm so glad I found this company! I had a short circuit that was causing my entire house to be on fire, and they were able to get me back up and running in no time at all. I'll definitely be using them again when I need electrical work done--and I highly recommend them to anyone else who needs help with their electrical problems!

Same exact experience as Gregory Newsome. Scheduled an appointment, he was a no-show. Talked to him again, rescheduled, no-show again.

Work was completed is the only good thing. They didn't listen to instructions on where outlets should be placed so we had to have walls repaired. They were late or didn't show up on more than one day. And they don't stand behind their work as we are now having problems under 2 years after the work was done.

Very helpful and friendly technician who was willing to explain everything and was very polite and concerned with us having the best experience!

After reporting the breakdown, this company responded immediately and arrived on site at the agreed time. The electricians got straight to work, accurately diagnosing the problem and then discussing possible solutions with us. They were very courteous and demonstrated their expertise, explaining every step of the repair to us. The work was carried out with attention to detail and to the highest safety standards. Once the work was completed, they were carried out to make sure everything was working properly. I would highly recommend the services of this company as they are reliable and professional.
