How Size, Material Grade, and Airflow (CFM) Change Price

- Size: single 6–8″ diffusers are low-cost; anything over 24″ or a multi-slot run increases cost sharply—expect +50% to +200% for custom lengths beyond standard sections.
- Material grade: plastic to painted aluminum typically increases cost by $20-$150; stainless or architectural finishes add $100-$300 per unit.
- Airflow and balancing: diffusers with high CFM capacity or integrated dampers cost $40-$200 more; custom volume control (VCD) adds $75-$250.
- Numeric thresholds: linear slot pricing often quoted per 24″ section; acoustic lining is typically added for runs >48″ and costs $8-$18 per linear ft extra.

- Bundling: request a per-unit discount for 5+ identical units or for full-house HVAC register replacement.
