Survey → fabricate ducts → install runs and dampers → controls and airflow commissioning.
Embed sleeves during rough-in — cutting finished walls later is expensive.
Balancing grilles is what makes the system match the design.
Stages: survey and air-change calc → layout → duct fab → install → controls → commissioning with measurements.
Agree grille positions early — moving them later often means opening ceilings.
Silencers and vibration isolators keep fan noise out of occupied rooms.
Keep a commissioning report with room airflow as your handover record.
