Our Services
HVAC, PLUMBING and process piping engineering, design-build & OPM (owners project manager)
At Trinidad Engineering, we believe that every project starts with a clear understanding of the need. We don’t just design—we listen, investigate, and ensure every detail is addressed. Our process involves collaborating with owners, managers, and technical teams to uncover the full scope of the project. Sometimes, this means bringing out our own test equipment to dig deeper.
From construction drawings and permit documents to building assessments, reports, and ongoing support, we provide solutions that meet the needs of everyone involved, before, during, and after the project. Whether you're working on a retrofit, addition, or new construction, we’re there to guide you every step of the way.
While much of our work is with building owners and facility management, we also partner with design-build contractors to ensure seamless project execution.

Consulting and engineering services
In addition to traditional professional stamped HVAC, plumbing, and process piping engineering, Trinidad Engineering offers specialized consultation for complex HVAC airflow, water flow, and control issues.
What sets us apart is our hands-on approach. Since 1996, we’ve bridged the gap between engineering and trades by conducting specialized testing of HVAC and process piping systems. We understand that some problems can’t be solved with textbook knowledge alone. To truly solve difficult issues, you need to go beyond theory and dive into the practical world of pumps, fans, and control sequences.
We’ve earned a reputation for solving tough problems alongside some of the best balancers and contractors in the industry.
