A high-velocity central air-conditioning system is an air-cooling system that operates through small, flexible tubes that are inserted into and wrapped around and above closets, crawlspaces and ceilings. It is typically installed in buildings with no air ducts.

Older homes and other buildings with baseboard heat or radiators tend to lack ductwork. This means the only way to air condition the building is with window units, which are unwieldy and loud, or by installing ductwork, which is often expensive and aesthetically unappealing.

High-velocity central air-conditioning systems, on the other hand, maintain a building's architectural integrity while providing comfortable, cool forced air. The outlet holes for forced air are 2 inches in diameter, so they are scarcely noticeable. The air-handler unit is compact enough to be mounted in a basement, attic or closet. Sound-absorbing material surrounding the tubing mutes the sound of forced-air movement.

Other benefits of high-velocity central air-conditioning systems include the ability to remove roughly one-third more humidity than standard air-conditioning systems and a lack of drafts, so the system maintains an even temperature throughout the building's interior. Manufacturers of high-velocity air-conditioning systems often custom design the installation to outfit homes with open floor plans, wood-beam construction and historical designs.
