Who We Are
Our Story
Nor Cal Mechanical LLC was founded with a single mission: bring the highest standard of mechanical contracting to Northern California homes and businesses. From day one, we built our reputation on doing the job right — the first time. We chose the best brands Mitsubishi and Trane to provide our customers with worldclass performance and reliability all while running with minimal energy consumption. There is No substitute for quality!
Our crews are members of Plumbers & Steamfitters Local 290, which means every technician arrives with rigorous trade training, ongoing education, and a commitment to safety that goes beyond code minimums.
Today we serve residential homeowners, commercial property managers, and general contractors across Southern Humboldt and Northern Mendocino counties — handling everything from a single mini-split installation to full mechanical system design and build-out.
