Without power, your business and your customers are left sitting in the dark. You are not going to bring in more people without power to your business, and you cannot really take proper care of the customers you already have. With that in mind, you need a Long Island electrician who can provide you with the quality and reliability you need to get your power back on quickly and keep it on. A power outage caused by the weather or an issue with the electric company can strike any business, but when there is a legitimate power issue at the business location that is not related to outside sources, you need an electrician in Long Island to fix it right away.

Here at Fielack Electric, we offer 24/7 service for emergencies and businesses that have late hours, so you can make sure you get the help you need when you need it, not hours later. With highly trained technicians and competitive pricing, you can feel comfortable about the help you get from us. You will not overpay for the services we offer, and we will get the job done right, the first time. We have been Nassau County electricians since 1988, and we are members of the BBB and Angie’s List. We are also licensed, bonded, and insured, so you will not have any worries about the work being completed correctly, quickly, and safely. Our thousands of satisfied customers and excellent BBB rating speak for themselves, so you can feel good about reaching out to us for your commercial electrical needs.
