About Us

Consolidated Electric was founded in 1984, and still maintains several service and maintenance clients dating back to that period. Clearly, we value long-term client relationships and doing work that keeps our partners satisfied.

Located in New Haven, Connecticut, we have steadily grown our business to serve a wide variety of customers throughout the state. In addition to residential jobs of all sizes, we take on industrial projects, new construction and renovation, as well as telecommunications, fire alarm, security, and control systems. We have been privileged to be a part of several municipal, state, and federal renovations.

Our clients work with us because we are large enough that we are never short of manpower or skills, yet small enough to be nimble and react to immediate needs. We believe in clear communication and being available to our clients. Our leadership is easy to reach and takes a hands-on approach to all of our projects, no matter the size.
