TNL Electrical is a California-licensed electrical contracting company headquartered in Sebastopol, CA, specializing in building automation systems (BAS/BMS) and industrial electrical services. We serve commercial, industrial, and residential clients across Northern California.
We were founded to fill a gap in the market — clients needed a contractor with deep expertise in both electrical systems and building automation, not one or the other. TNL brings both under one roof, delivering integrated solutions that work seamlessly from panel to controller to cloud.
Every project we take on gets the full attention of our ownership team. We're not a large firm that wins your bid and hands you off to a junior crew. When you hire TNL, you get experienced professionals who are accountable for the outcome.
Honest pricing, transparent communication, and work we stand behind.
Controls work demands accuracy. We get it right the first time.
We show up, we communicate, and we deliver on our commitments.
We stay current on BACnet, open protocols, and smart building tech.
With years of hands-on experience in building automation and industrial electrical systems, the founder of TNL Electrical built the company on a simple principle: do excellent work, charge fair prices, and always put the client first.
From DDC panel fabrication to full BAS commissioning, every project reflects the same commitment to quality craftsmanship and technical excellence that TNL was built on.
