HLC Electric Supply Co. was founded in 1982, but our roots extend much deeper. In the 1950s, Charley and Art Contreras, two brothers, started a company named Industrial Marine, dedicated to servicing and reselling 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. A significant number of these systems continue to function 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 today, and into the future, HLC has the power to keep YOUR power 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's attention to detail and dedication to craftsmanship set him apart in the industry. He is a family man, happily married and the proud father of two lovely young kids. He loves sports and is an avid saltwater fishing enthusiast in his spare time.

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!
