I worked at EEC for a little over two years. I have never had a better company have my back. When COVID hit, they made sure we had jobs. Unfortunately, I have some medical problems that have caused me to resign, but when I was trying to get help and work, Eric always had my back. He was very understanding and willing to help. EEC treats every employee like family!

We've never hired an electrician before, but we needed a professional to come fix some wiring in our "new" 15 year old home. Electrical issues are definitely not something we want to tackle ourselves. We were extremely pleased with the service we received from Essex. The electrician arrived on time, was very professional and courteous, and figured out the problem and solution quickly. The bill was also very reasonable and worth it. Best of all, we have peace of mind that the job was done right. Will definitely use them again. Have recommended them to many friends and family.

We just had a generator installed, and we are beyond impressed! Not only were the employees very professional and respectful, they were early! Even the city inspector was impressed with their craftsmanship and attention to detail! We will definitely have them back for all of our electrical needs!

A great experience with a trustworthy company. We reached out to schedule someone to learn more about our basement project. We were contacted right away by someone who was eager and flexible. Eric, the owner, personally did the walk-through and estimate. He was extremely knowledgeable, honest and personable. He genuinely was open and enthusiastic about the potential of our basement. After having other estimates completed by local professional construction companies, we decided to work with Essex Electrical & Company because of their transparent and competitive pricing and because of the thorough and direct information we got during our consult. Throughout the project we were kept up to date on cost and the anticipated length of the project. We were beyond impressed with the craftmanship and service we received.

Was doing a training exercise with my sales team on the value of calling on local contractors in order to establish relationships within our community; especially with electrical contractors because we use them for large scale projects. Was hung up on quickly by an gentleman who clearly didn't have his morning coffee. Sad

Had reached out to this company last week and talked to a really nice young woman. Called back with my partner and our sales staff on the phone in order to demonstrate the value of partnering with local contractors instead of outsourcing larger companies within the city of Chicago and was hung up on within seconds. Judging by what I see on their google business page I don't think they'll be around much longer! Bad business doesn't breed success.
