Design‑Build & Compliance, Handled

From concept to commissioning, we deliver a turn‑key path to a safe, efficient ventilation system. Our team performs load and airflow calculations, duct and equipment sizing, and layout coordination with your architect, GC, and trades. We prepare submittals and help navigate plan check and permitting.

We design to ASHRAE 62.1 objectives and meet Title 24 and CALGreen requirements across Los Angeles and surrounding jurisdictions. We coordinate with fire and building departments and observe local AQMD guidelines where applicable. Final commissioning includes Testing, Adjusting, and Balancing (TAB) per industry standards, sequence verification, and close‑out documentation for your records.
