Installation Capabilities
Shop Assembly
We provide ductwork assembled using modern equipment that ensures precise dimensions and quality control. Shop assembly provides several advantages:
- Consistent quality in a controlled environment
- Faster on-site installation
- Reduced weather delays
- Better material utilization
- Pre-assembled sections for complex installations
Field Installation
Our sheet metal workers coordinate duct installation with other trades, ensuring proper clearances, support, and integration with building systems. We handle:
- Overhead duct routing and support
- Underground duct installations
- Coordination with structural, electrical, and plumbing trades
- Installation in occupied spaces with minimal disruption
- Sealing and insulation for energy efficiency
Quality & Testing
Duct Leakage Testing
For projects requiring LEED certification or specific performance standards, we perform duct leakage testing to verify system integrity. We seal joints and connections to meet project specifications and energy code requirements.
Installation Standards
Our installations follow SMACNA (Sheet Metal and Air Conditioning Contractors’ National Association) standards for:
- Duct construction and reinforcement
- Joint sealing methods
- Hanger and support spacing
- Clearances and access requirements
Projects
We install ductwork systems across multiple sectors:
- Schools
- Complete air distribution systems with VAV boxes and economizers
- Hospitals
- Specialized exhaust systems for operating rooms and laboratories
- Libraries
- Low-velocity duct systems for quiet operation
- Industrial
- High-pressure systems for process ventilation
- Commercial
- Office buildings with energy-efficient distribution systems
Union Craftsmanship
Our sheet metal workers are members of Sheet Metal Workers’ Local 73, bringing certified expertise to every installation. Our technicians are trained in modern assembly techniques, welding, and installation methods.
Coordination & Planning
Duct systems require careful coordination with architectural features, structural elements, and other building systems. Our superintendents work closely with:
- Mechanical engineers to verify duct sizing and routing
- Architects to coordinate with ceiling systems and soffits
- General contractors for installation sequencing
- Controls contractors for damper and sensor integration
- Fire protection contractors for penetrations and firestopping
Specialty Systems
In addition to standard HVAC ductwork, we provide specialized systems for unique applications:
- Kitchen Exhaust
- Grease duct systems meeting NFPA standards
- Laboratory Exhaust
- Corrosion-resistant ductwork for fume hoods
- Clean Rooms
- HEPA filtration and laminar flow systems
- Industrial Ventilation
- Heavy-duty ductwork for manufacturing processes
- Dust Collection
- Specialized ductwork for material handling systems
Why Ductwork Matters
Properly designed and installed ductwork delivers conditioned air efficiently, reduces energy costs, and ensures occupant comfort. Whether you need a complete air distribution system for new construction or ductwork modifications in an existing facility, we provide and install systems to meet your project requirements.
