Penco Electric has been servicing my generator for the past few years, and they have been great!  So much so, I inquired about the installation of a 240 outlet for EV charging at home.  Paul was very patient and kind with me.  We discussed the location of where I wanted the outlet.  Shared photos.  He explained the details of what would be involved with the installation.  Installation day:  Jorge arrived!  Within minutes I was at ease.  He has a manner about him that is very calming.  We discussed the plan, and began dismantling the wall.  Jorge was able to make the new outlet appear as if it had always been there.  He left no trace…above and beyond!  There was nothing left for me to do.  Jorge, I will forever be grateful for all that you did.  It looks fantastic!  Thank you!

Our 20-year-old Generac went down. Another company tried to sell us a new generator for $15K. Penco was able to repair our existing generator for $2K (parts & labor). We're back in service.

From my initial contact with Paul to solidifying our transaction for a new natural gas generator with Marion, we could't be happier with the value added services and product we received from Penco!!  They were professional, thorough, efficient and accommodating to meet our installation expectations.  I have already passed their contact information along to family and friends considering a natural gas generator and will continue to do so.

What an amazing company to work with. From start to finish everything was organized and great quality of work. Paul is amazing! He answered any questions I had, responded to all my emails in a timely manner and has great staff. Customer service is #1 when working with any company because it provides a picture that they stand by their work and products. I am excited with my Generak and new ecobee thermostat,  and glad I found a forever company to work with. Thank you Paul and your team.

Friendly, professional, and high quality work. We had a complete service upgrade performed, from 100A service with an old 20-space panel to 200A with a 40-space panel and whole-house surge protector. Penco did an excellent job, especially George, who spent a lot of time getting everything done to a high standard with the new panel. There was an issue with the initial install not meeting ComEd requirements for the outside of the house, but that was quickly corrected at no charge, and Penco even returned one final time to clean up messy wiring that ComEd left behind. Thanks very much!

Penco Electric did a really good job installing our generator. The work included excavation, gas line extensions and electrical. Everything from beginning to end was timely, professional and hassle-free. Competitive pricing and excellent install crew. Marion did a great job every step of the way, answering all questions and managing all details. We are completely satisfied and highly recommend Penco Electric.
