Commercial Ductwork Service

• Lost Productivity & Customer Discomfort: Hot spots in offices or cold drafts in retail aisles drive away business and hinder staff performance.
• Premature Equipment Failure: Constant strain on rooftop units (RTUs) or large air handlers due to poor duct design leads to costly, untimely breakdowns.
• Skyrocketing Utility Bills: Leaky or unbalanced duct systems in large buildings waste enormous amounts of energy, directly impacting your operating budget.
• Indoor Air Quality & Compliance Risks: Inadequate ventilation or contaminated ducts can violate OSHA guidelines or building codes, posing health risks and liability.
• Fire & Smoke Code Violations: Improperly installed fire/smoke dampers or non-compliant materials can fail inspection and create serious safety hazards.

Our Commercial-Grade Service Capabilities

We handle projects from tenant fit-outs to full-building retrofits with a focus on precision and durability.

1. Design-Build & Engineering:

• Collaboration with Project Teams: We work with architects, engineers, and general contractors from blueprint stage.
• CAD-Driven Design & Shop Drawings: We create detailed fabrication and installation drawings for complex layouts, coordinating with other MEP systems (electrical, plumbing, sprinklers).
• Advanced Load & Pressure Calculations: Using software to model airflow for large, multi-zone spaces with varying occupancy and heat loads (e.g., kitchens, server rooms, retail floors).

2. Custom Metal Fabrication & Installation:

• In-House Fabrication: We fabricate custom galvanized steel ductwork, spiral metal duct, and fittings in our shop to precise specifications, ensuring quality and speeding up on-site installation.
• Heavy-Duty Supports & Rigging: Properly engineered hanger systems using unistrut, rod, and channel to support large ducts per SMACNA standards.
• Specialized Systems: Installation of kitchen exhaust hood ductwork, laboratory fume exhaust, and dust collection systems with appropriate materials and sealing.

3. Critical System Components:

• Fire Damper & Smoke Damper Installation: Precisely installed and accessible for inspection, ensuring life safety code compliance.
• VAV (Variable Air Volume) Box Integration: Expert connection and balancing of VAV boxes for modern, efficient zoning.
• Acoustic Lining & Sound Attenuation: Installing duct liner and sound traps to meet noise criteria (NC) levels in offices, conference rooms, and tenant spaces.
• Pressure & Airflow Balancing (TAB): Partnering with or providing Testing, Adjusting, and Balancing to certify system performance against design specs.

4. Maintenance & Retro-Commissioning:

• Large-Scale Duct Sealing: Using aeroseal technology or professional mastic to seal leaks in extensive duct runs inaccessible above ceilings.
• Hygienic Inspection & Cleaning: Following NADCA standards for commercial buildings to address dust, grease, or microbial contamination.
• System Optimization Audits: Evaluating existing ductwork for performance deficits and designing upgrade paths for better efficiency and comfort.

The Commercial Ductwork Difference: Scale, Codes, and Complexity

• Scale & Access: Working in occupied buildings, coordinating with tenants, and navigating tight mechanical rooms or high ceilings.
• Strict Code Adherence: Compliance with IMC, IBC, NFPA 90A/B, and local mechanical codes is non-negotiable. We build to permit and pass inspection.
• Material Specifications: Using heavier gauge metals, industrial-grade insulation, and specialized components (grease duct, cleanroom panels) suited to the application.
• Performance-Based Outcomes: Systems are measured and balanced to deliver specific CFM, static pressure, and ventilation rates (cfm/person) as required by design.

Why Partner with a Specialty Commercial Contractor?

General HVAC contractors often lack the specific engineering, fabrication, and code expertise for complex commercial work. The risks of getting it wrong—from comfort complaints to failed inspections—are too high. We provide the single-source accountability for your duct system, from design through to certified performance.

Protect Your Business Environment & Operating Budget

Your building's airflow system is a silent partner in your business success. A well-engineered duct system is an investment in employee well-being, customer satisfaction, and energy cost control.
