What is claimed is: 1. A zone climate control system for retrofitting to an existing forced-air system, the existing forced-air system including a blower, at least one of a heater and a cooler, a conditioned air plenum, and a plurality of air ducts, the zone climate control system comprising: a plurality of inflatable bladders, each disposed within a respective one of the air ducts; a plurality of air tubes, each coupled to a respective one of the bladders and extending through a respective one of the air ducts into the conditioned air plenum, wherein the plurality of air tubes extends outside the conditioned air plenum; a plurality of valves each coupled to a respective one of the air tubes; an air pump coupled to the plurality of valves to provide pressure and vacuum; and a computer-controlled valve actuator coupled to the plurality of valves for selectively coupling each air tube to a respective one of the pressure and the vacuum to accordingly inflate or deflate a respective one of the bladders and thereby block or pass air from the conditioned air plenum through the respective air duct. 2. The zone climate control system of claim 1 wherein: the computer-controlled valve actuator is mounted to the outside of the conditioned air plenum. 3. A forced-air system comprising: a blower; at least one of a heater and a cooler coupled to the blower; a conditioned air plenum coupled to the at least one of a heater and a cooler; a plurality of air ducts coupled to the conditioned air plenum; a plurality of air vents each coupled to a respective one of the air ducts; a plurality of bladders, each disposed within a respective one of the air ducts; a plurality of air tubes, each coupled to a respective bladder and extending from the respective bladder through the respective air duct into the conditioned air plenum; a plurality of valves, each valve coupled between the air pump and a respective air tube; a valve manifold coupled to the air pump and containing the plurality of valves; an air pump coupled to the plurality of air tubes to inflate and deflate the bladders; and a mounting strap coupled to the bladder and to the respective air vent. 4. The forced-air system of claim 3 wherein the mounting strap includes: an air tube clamp coupling the air tube to the mounting strap; and a mounting clamp coupling die bladder to the mounting strap.
