HLC Electric Supply Co. was founded in 1982, but our roots extend much deeper. During the 1950s, brothers Charley and Art Contreras began a venture called Industrial Marine, which serviced and resold industrial electrical equipment. For over twenty years, in an era known as the golden age of electricity, these brothers supplied an alternative for electrical distribution and motor control equipment when manufacturers fell behind the rapid industrial growth. Numerous systems from that era are still in use today. Now, three generations later, HLC Electric proudly serves our community and clients across the nation, leveraging the wealth of knowledge and experience we've accumulated in electrical systems. From the 1950s to the present and beyond, HLC has the capability to ensure YOUR power stays on!
Charlie Contreras serves as the owner and head technician at HLC Electric Supply Co.. He is a licensed C10 electrician and a specialist in electrical distribution equipment. Charlie stands out in his field due to his keen attention to detail and commitment to quality workmanship. Charlie is married and takes pride in being the father of two beautiful young children. In his free time, he enjoys sports and is passionate about saltwater fishing.

Recommended Customer Reviews

The best! On time and Charlie was sooo friendly and helpful. Very knowledgeable and found/fixed our problems very quickly. Reasonable rates. Can't say enough good about Charlie and the service he provides. Can't find people like this these days who go beyond the call. Would definitely use HLC/Charlie again, and recommend them to anyone who needs electrical service. Thank you, Charlie!

Margaret and Charlie job well done!! Very polite and friendly people would recommend this location if you are in need of electrical supplies.

We were looking for an older breaker cover for our breaker box and most places don't carry it anymore. Who carries parts for Pushmatic circuit breakers in this day and age? After looking around several hardware and electrical supply stores, one of them recommended HLC to us. The place isn't very easy to find and the warehouse is hard to navigate through on your own, but they carry a wide variety of used older breaker switches, covers and other parts. The staff was helpful and he helped locate the exact part we were looking for. Buying parts in bulk will give you a better deal on parts, but if you aie looking for rare parts, give them a try!
