A Brand New Brand!
We thought it was time our bear changed it up a little. He's been cooling himself on that ice block for over 37 years! Although our logo has changed, ESI still provides the same quality of service and expert solutions that we have been delivering since 1975.
ESI offers a variety of energy saving solutions like LED lighting, solar, fuel cells, and energy management systems. Our innovative products and market alignment allows us to provide customers with tangible real solutions at a very competitive price.
After completion of a project, our service division takes over. From remote monitoring, and service alerts, to maintaining factory warranties through regularly scheduled maintenance, ESI service technicians maintain your system to exact specifics.
