High Velocity Systems
High-velocity HVAC systems deliver conditioned air through small-diameter flexible ducts, making them ideal for retrofits in older NYC buildings where traditional ductwork installation is impractical. Perfect for:
- Historic brownstones and pre-war buildings
- Residential and boutique commercial spaces
- Retrofit projects without existing ductwork
- Applications requiring minimal visual impact
Low Velocity Systems
Low-velocity systems operate at reduced fan speeds, producing significantly quieter operation while maintaining superior air distribution and comfort. Ideal for:
- Luxury residential and high-end commercial spaces
- Noise-sensitive environments (bedrooms, offices, studios)
- Multi-zone configurations requiring independent control
- New construction with planned ductwork
