Konopka Electric is without a doubt the company that you need to use for any electrical work you need to have done. Jim, Jillian and the rest of the team are the very definition of excellence and customer service. I could tell you a very long story of the problems we had with a generator that we purchased from another company, but the important part is that Konopka took care of all the (many) issues we had with that generator until we finally decided to replace it. They replaced the generator quickly and at a great price. You can't go wrong with Konopka. They truly care about their customers. You won't be disappointed.

I cannot say enough good about Konopka Electric. They were quick, efficient, so nice, and they worked with me and my mortgage lender to get paperwork completed timely. I would use Konopka Electric for any electrical work in the future, and would recommend others do the same.

Konopka Electric LLC has done a very good job installing our new Briggs and Stratton 26kvw generator. Jim and all of his crew are extremely professional. You can be sure that the job is going to be completed on time and will be done right!

Jim and his crew were professional, reliable, timely, and very responsive. Any issues that did arise were resolved quickly. I would highly recommend his services. Thanks Jim ! UPDATE: This is a review for a separate job that Konopka Electric just finished for me and if I could give 10 stars i would. It was a somewhat difficult job, not complex but difficult, and Jim had the most practical, reasonable, and affordable solution. His crew came in and did the job with minimal power out down time, and finished the job in a professional and timely manner. I would not hesitate to recommend Jim and his crew to anyone! Thanks Jim!

I had a standby generator installed by Konopka Electric, and they did a fantastic job. The electricians were professional, knowledgeable, and took great care throughout the entire installation process. Everything was completed efficiently and to a high standard. I would be more than happy to recommend their services to anyone looking to install a whole-house generator. I give you 5 gold stars for quick install and service's
