Spacepak small-duct HVAC installation and repair in SF. The smart choice for older homes without ductwork.
Hydroflow has extensive experience installing and servicing Spacepak high-velocity heating and cooling systems. Our technicians are trained to handle small-duct technologies, ensuring quality installation and reliable service in San Francisco and Marin County. Spacepak is an industry leader in small-duct high-velocity central air systems — perfect for older San Francisco Victorians and Edwardians where traditional 6-inch ductwork simply won't fit through existing walls and ceilings.
Traditional HVAC systems require 6-inch supply ducts that must be routed through walls and ceilings. In a San Francisco Victorian or Edwardian with plaster walls, existing framing, and no attic access, this is often impossible without destroying finishes. Spacepak's 2-inch flex tubing fits through existing wall cavities and can be run without major demolition. The high-velocity, small-volume delivery system provides excellent room-level comfort, dehumidification, and consistent temperature — without the visual intrusion of exposed ductwork.
Complete Spacepak installation including duct routing assessment, equipment sizing, air handler placement, and balancing. Permit handling and inspections included.
Monthly filter checks (high-velocity systems load filters fast) and quarterly or annual full maintenance including blower inspection, refrigerant check, and drain cleaning.
Airflow diagnosis, blower motor repair, refrigerant charging, and sound attenuator inspection and replacement. We carry common Spacepak parts for expedited repairs.
Small-duct high-velocity installation, maintenance, and repair for San Francisco Victorians and Bay Area homes.
