Vent Cap Systems are reusable caps, made from recycled plastic, that seal an HVAC system for diagnostic testing after a new install, energy audit, duct cleaning or duct repair. 

Installation is fast, according to the company. Energy auditors and HVAC service companies no longer have to use disposable vent or duct sealing film to seal duct vents. There is no film to throw away, and there is never any damage to the vent or surrounding areas, the company adds.
