The Arteries of Your HVAC System

Even the most advanced, high-efficiency equipment will underperform if connected to a poorly designed duct system. Restrictive, leaky, or improperly sized ductwork leads to hot and cold spots, high energy bills, and noisy operation.

We design all duct systems using ACCA Manual D standards to ensure proper velocity and static pressure. We focus on tight sealing and strategic layout to minimize resistance and maximize comfort.

Our Duct & Piping Services

  • Manual D duct system design and layout
  • Custom sheet metal fabrication and installation
  • Duct sealing and insulation to current energy codes
  • Static pressure testing and airflow balancing
  • Refrigerant lineset sizing, routing, and brazing
  • Nitrogen-purged brazing to prevent system contamination

Working with the Architecture

For new construction and renovations, we collaborate with builders and architects to route ductwork intelligently, avoiding unnecessary soffits and preserving the aesthetic integrity of the space while maintaining optimal airflow.

Frequently Asked Questions

Why is static pressure important?
Static pressure is the resistance to airflow within the ducts. If it's too high, the blower motor works harder, uses more energy, and delivers less air. We design ducts to keep static pressure within the equipment's optimal range.
Do you test the ductwork for leaks?
Yes, we seal all joints and connections meticulously and can perform duct leakage testing to ensure compliance with stringent energy codes.
