Low Voltage Technician Salary in Houston, TX (2026)

Aggregated data from Glassdoor, ZipRecruiter, Indeed, and Salary.com places the average between approximately $47,500 and $58,500 USD annually as of early 2026, depending on the methodology used. A mid-point of roughly $54,000 USD is a reasonable benchmark for a technician with 2-5 years of experience. Figures are base salary only and exclude overtime, vehicle allowance, and bonuses.

Entry-level helpers and first-year install technicians in Houston typically earn between $37,000 and $48,000 USD per year. ZipRecruiter data from March 2026 shows the 25th percentile in Houston at approximately $38,800 annually. Moving past this floor quickly requires picking up a specialty cert such as ESA Level 1 or a manufacturer training credential within the first 12 months.

NICET Fire Alarm Level II and III are the most widely cited credentials for pushing pay above the midpoint in Texas. Manufacturer certifications from Genetec, Lenel, Bosch, and Avigilon are also commonly listed in higher-paying Houston job postings. An ESA National Installation Technician credential can differentiate a candidate for alarm and access control service roles that pay toward the top of the mid-level band.

Generally yes. Fire alarm technicians - particularly those with NICET credentials required for permitted commercial work - tend to earn at the upper end of or above the standard low voltage range. Salary.com data from 2026 shows an Electrical Low Voltage Journeyman (often fire/security focused) averaging around $65,000 USD in Texas, compared to a Low Voltage Cable Technician at roughly $62,000 USD.

Dallas and Austin average slightly higher on an hourly basis per ZipRecruiter and Indeed data, with Dallas Indeed data showing approximately $27.44/hr versus Houston at $26.08/hr as of early 2026. However, Houston's large petrochemical and medical-center project market creates frequent overtime opportunities that can close the gap in total annual earnings. Austin's hyperscale data-center growth is driving senior-end demand that can push experienced techs above Houston rates.

Houston is one of the stronger US markets for low voltage technicians due to its concentration of petrochemical plants, medical complex facilities, data centers, and active commercial construction. The BLS projects continued demand growth for security and building-systems installers nationally. Texas also has no state income tax, which improves net take-home relative to comparable roles in higher-tax states.

Service-contract technicians who handle troubleshooting, maintenance, and recurring client accounts generally earn $4,000-$8,000 more per year than pure installation crew members at the same experience level. Service roles require stronger diagnostic skills and direct client communication, which employers compensate at the higher end of each tier band. If you are currently in an install-only role, transitioning to a service-tech position is one of the most direct ways to increase base pay without changing employers.

Active Houston employers in this space include Facility Solutions Group (FSG), Siemens Smart Infrastructure, IES Communications, Convergint Technologies, Johnson Controls, Sciens Building Solutions, Wachter, and Securitas Technology. Many large general contractors on petrochemical and healthcare builds also hire direct low voltage leads and foremen outside of the traditional integrator channel.
