Ductwork Fabrication & Installation

Precision-Built Airflow Systems Designed for Comfort and Efficiency

Behind every high-performing HVAC system is a well-designed and properly installed duct system. Even the most advanced air conditioner or heat pump can’t deliver comfort if the ductwork is undersized, leaking, or poorly routed.

At Calvary Mechanical LLC, we specialize in custom sheet-metal duct fabrication and professional installation for both residential and commercial applications. Every system we build is engineered to deliver maximum airflow, quiet operation, and long-term reliability.

Custom Ductwork Fabrication

Unlike many contractors who rely solely on prefabricated duct sections, Calvary Mechanical operates a fully equipped in-house sheet-metal fabrication facility.

This allows us to:

  • ✅ Design and build duct systems to exact project specifications

  • ✅ Maintain full control over material quality, fit, and finish

  • ✅ Offer faster turnaround times for construction and retrofit projects

  • ✅ Deliver cleaner installations with precise joints and sealed seams

  • ✅ Fabricate with galvanized steel, aluminum, and lined duct board to suit any environment

Every piece we produce is cut, assembled, and sealed according to SMACNA standards to ensure peak airflow performance and lasting durability.

Professional Duct Installation

Once fabrication is complete, our experienced installation crews handle the complete duct system setup — from design layout to final testing.

Our installation process includes:

  • ✅ Site measurement and airflow load evaluation

  • ✅ Proper duct sizing based on Manual D or engineered drawings

  • ✅ Airtight sealing using approved mastic and UL-rated tapes

  • ✅ Precision alignment for minimal airflow resistance

  • ✅ Insulation wrapping to prevent energy loss and condensation

  • ✅ Final pressure testing and balancing for system verification

We ensure that every joint, takeoff, and transition is installed with precision — because we know your HVAC system’s performance depends on it.

Why Quality Ductwork Matters

Your duct system is the circulatory system of your building. When it’s designed and installed correctly, you’ll experience:

  • ⚙️ Improved system efficiency and airflow

  • 💡 Lower energy costs

  • 🌡️ Consistent room-to-room comfort

  • 🔇 Quieter operation

  • 😷 Cleaner, healthier indoor air

Poorly designed or leaking ducts, on the other hand, can waste up to 25–30% of conditioned air, forcing your HVAC equipment to work harder and shortening its lifespan.
