Cable dampers aren’t something you often see in residential construction, but the Beacon Hill Passive House mechanical system design included cable dampers with convenient controls throughout the home for maximum comfort and efficiency.
Cable dampers are a mechanism that allows you to open/shut your heating and cooling system vents at specific areas of your home to manage the air flow to different rooms. Typical residential construction will have very minimal control over air flow from the HVAC system, in the form of a vent that has a knob to open/close and direct the air.
