About Us

Our Story

Colwell Electric has been serving Houston and the surrounding communities since 1990. Our family-run business is managed by third and fourth generation electricians who care about our customers and our community. Our goals are to provide the highest quality service with honesty and integrity. We believe in working hard and doing the job right the first time. Colwell Electric is a proud member of the Better Business Bureau and the Houston Chamber of Commerce

Founded in 1990, Colwell Electric remains a family-owned business with three generations of the Colwell family working at the company. Our experience with GE Zenith Controls Automatic Transfer Switches goes back even further...more than 50 years.

Colwell Electric is an electrical contract company that has been an approved GE Zenith Factory Service Center for the past 27 years handling approximately 35 plus GE Zenith cases annually.

We have factory-trained technicians with a combined total of 77 years of experience that specialize in automatic transfer switch service, technical services, general electrical service, and that assist the GE Zenith paralleling switch gear team.  Two of our factory trained technicians dedicate 90% of their time to automatic transfer switch work and they have the skills and expertise to retrofit a legacy automatic transfer switch with a new controller and/or install a new automatic transfer switch in an existing cabinet.  

We also stock a large assortment of GE Zenith automatic transfer switch parts for the various models of transfer switches, from legacy models to current models, and we keep our service trucks stocked with parts.
