The new product out that is being used by many A/C contractors is the Mighty Pump. It is a lightweight handheld pump that requires no electric and has more suction power than wet/vacs. Simply attach the Mighty Pump hose to the outlet of the A/C condensate drain line and pump until the line is clear. It is simple and quick to use and is inexpensive. It is found at www.ACDrainPump .com
