Results

The HVAC system for the new Angelus Corporation facility was installed and commissioned to provide a fully integrated heating, cooling, and ventilation solution aligned with the building's operational and occupancy needs. Equipment selection and sizing were based on engineered load calculations to support efficient performance and long-term reliability.

The project included new HVAC equipment, associated ductwork, piping, and controls to deliver balanced airflow, precise temperature control, and code-compliant ventilation throughout the facility. The systems were designed to maintain proper static pressure, optimize energy efficiency, and support continuous operation.

All mechanical work was completed per approved construction documents, manufacturer requirements, and applicable mechanical and energy codes. Final commissioning verified airflow quantities, equipment operation, electrical performance, control sequences, and safety interlocks to confirm the system operated as designed.
