Commercial Ductwork

In restaurants, offices, stores and mixed-use buildings, ductwork decides whether your HVAC system delivers comfort or just runs up the bill. Liberty HVAC installs, modifies and repairs commercial ductwork across Brooklyn, Queens, the Bronx, Staten Island, Manhattan, Nassau and Westchester.

Commercial ductwork services

• New duct systems for rooftop units, split systems, air handlers and make-up air units
• Tenant build-outs and renovations: relocating, extending or resizing ducts for a new layout
• Duct repair and sealing to stop air loss
• Insulation of supply ducts in unconditioned spaces
• Airflow balancing for even temperatures across the space
• Diffusers, grilles and registers

Signs your commercial ductwork needs attention

• Hot and cold spots, or complaints from staff and customers
• Equipment running nonstop but not keeping up
• Rising energy costs
• Noisy, rattling or whistling ducts
• Dust, odors or visible damage after construction

Why it matters

Properly designed and sealed ductwork lets your equipment work at its rated capacity, keeps the space comfortable and reduces wear on compressors and fans. During a renovation, getting ducts right the first time avoids costly rework.

What's included

• Site survey of the existing system and layout
• Duct layout matched to your equipment and floor plan
• Fabrication-ready measurements and installation
• Sealing, insulation and connections to equipment
