Powering projects across Texas and New Mexico with experience you can trust.
First Source Electrical Contractors LLC is a young company founded with over 30 years of experience on our personnel. We serve residential, commercial, and industrial clients across Central Austin, surrounding areas, the whole State of Texas, and New Mexico.
Founded by an electrician. Still run like one.
We've been working in big-scale projects from Schools to high-rise hotels, from Hospitals to Data Centers and microchip / semiconductor fabs. At the same time, no job is too small — our goal is to keep growing the company depending on demand.
We educate our new generations and of course offer the best experience to our clients by finishing on time and in the most professional manner. Building good electricians and relationships — not only with clients, but with other trades — is the key for us.
Ethics, professionalism, and honesty are our core values. Our employees are not just a number — they are a fundamental part to make all this happen, and we take care of them. We are members of the IEC (Independent Electrical Contractors).
Values we wire into every job.
Safety
Every installation follows or exceeds current NEC standards. No shortcuts, ever.
Craftsmanship
Clean wiring, labeled panels, documented work. The details matter.
Integrity
Honest estimates, straight answers, and work that holds up long after we leave.
Innovation
From EV chargers to smart panels — we stay current so your systems stay ahead.
Licensed, credentialed, and genuinely skilled.
Our team is led by Adrian Mendoza (President / Master), Miguel Tijerina (Operations Manager), and Cesar Sandoval (Owner). Backed by a skilled crew of electricians, apprentices, and a safety representative — every role matters.
