He knows that his reputation is on the line with every single project regardless of size or scope. His hands-on approach leads everyone at ACH to adopt a strong commitment to quality. He operates with the ultimate goal to provide superior service throughout every stage of the project including a competitive bid, accurate submittals, teamwork with other trades on-site, and a responsive service and controls department throughout the warranty period and beyond.

Providing Comfort, Building Relationships throughout California

Smarter HVAC Starts with BIM Coordination

Tailored Design/Build Solutions Powered by Revit, Navisworks & Trimble

At ACH Mechanical, we’re equipped with over 10 years of experience in Building Information Modeling (BIM), allowing us to deliver highly coordinated HVAC systems with precision, efficiency, and speed. We use advanced tools like Revit, Navisworks, and Trimble to support pre-construction planning and streamline the design-build process.

Whether we’re designing for a new commercial facility or retrofitting an existing building, our team takes a hands-on approach—personally verifying as-built conditions and identifying the most efficient, cost-effective solutions for your space.

  • Reuse of existing components when possible to meet budget and scope
  • Fully tailored 3D models based on client needs, timelines, and budget
  • Pre-construction coordination using Revit, Navisworks & Trimble
  • Existing building surveys & remodel planning
  • Clash detection and trade coordination
  • Fabrication-ready digital components
  • Layout and field accuracy via Trimble

ACH is equipped and ready to use one of our greatest tools – BIM - on your next project. Together, let's design smarter.
