SYS · SERVICE & REPAIR

Service & Repair

When your facility's electrical system goes down, time is money. Our team is available 24 hours a day — scheduled maintenance or emergency response — across commercial, light industrial, institutional, manufacturing, and healthcare facilities throughout Delmarva. Call 302-629-9400 and speak to our dispatch team directly.

SYS · INSTALLATION

Installation

We design and install the full range of commercial and industrial electrical systems — from VFDs that cut motor energy draw to switchgear, CT cabinets, equipment controls, and Building Automation Systems that give facility managers visibility and control. Tell us what your facility needs and we'll quote it.

SYS · GENERATORS

Generator Installation and Maintenance

Power outages cost facilities far more than a generator. We handle the complete scope: load calculations sized to your actual demand, transfer switch installation, and integration into your existing electrical system. Ask about a preventative maintenance agreement to keep your backup power ready when you need it.

SYS · LIGHTING

Building and Parking Lighting

LED retrofits pay for themselves — lower energy bills, longer bulb life, less maintenance. We upgrade building and parking lot fixtures and handle repairs to existing lighting, including lamp and ballast replacement. Get a quote and see what the payback looks like for your facility.
