Repair small-diameter high-velocity duct systems found in older homes and historic properties.
Repairing Small-Diameter High-Velocity Duct Systems
High-velocity duct systems use small-diameter, typically 2 to 3 inch flexible tubing to deliver air at much higher pressure and velocity than conventional ductwork, allowing installation in older homes and historic properties where there is not enough space for standard-sized ductwork within walls, ceilings, or floor joists. These systems rely on aspirating outlets that mix the fast-moving supply air with room air as it exits, and they operate at pressures and velocities significantly higher than conventional residential duct systems, which means the components, connections, and repair techniques differ from what applies to standard flex or rigid duct.
The most common failures we see in high-velocity systems are damage to the small-diameter tubing itself from the tight radius bends these systems often require to fit through structural cavities, since a kink in 2 inch tubing has a proportionally larger impact on airflow than the same kink would in a standard 8 inch duct, and outlet or aspirator damage where the specialized fitting has become dislodged or damaged. We repair damaged tubing sections by splicing in matching diameter high-velocity duct rather than substituting standard flex duct, since the pressure and velocity characteristics of these systems require components rated for the application, and standard duct components can fail or perform poorly under the higher operating pressures involved.
Georgetown has a number of historic and older homes, particularly in the downtown square area and surrounding older neighborhoods, where high-velocity systems were installed specifically because the home's construction, plaster walls, minimal joist bays, or existing finished spaces, made conventional ductwork impractical without significant demolition. Repairing these systems requires familiarity with their specific components and operating characteristics, since a technician unfamiliar with high-velocity design might misdiagnose a properly functioning but unusual-sounding aspirating outlet as a defect, or attempt a repair approach that works for conventional duct but does not hold up under high-velocity operating pressure. Repair costs typically run 300 to 900 dollars depending on the extent of tubing damage and accessibility within the home's specific construction.
