1. Check to see if the dripping is coming from one of the copper pipes, if it is you can put insulation on it. The copper pipes coming from the outside unit are super chilled, and if the insulation has worn away, the ice cold pipes are exposed to warm humid air. It is just like a ice cold glass of water on a warm summer's day. The humidity in the air condenses on the glass. Covering the pipes with insulation will keep the warm moist air from touching the pipes, and the leaking should stop.

2. If the leaking is coming from a white PVC pipe, that is most likely your drain line. When warm humid air from your house flows over the evaporator coil, the water condenses on the coil and drips into the drain. If you use your A/C frequently, the drain line fills with water. That buildup of drain line water can cause things to grow in it: algae. Pretty soon the algae will take over, clogging the pipe. Flushing the drain line with hose water will clear the pipe. Just be sure to have a towel or bucket nearby to catch any water from the hose.


3. Finish it off by vacuuming out the drain line outside. In many cases the drain line will be outside near the Condenser unit. When your A/C is running, it is easy to find, the condesation will drip into this pipe and drain outside. When it isn't running it may be a little difficult to detect, but there shouldn't be too many pvc pipes exiting your house. If it is near the Condenser, chances are it is the drain line. Take a shop vac and attach it to the end of the drain line. Turn it on and suck out the goop inside. You might need to seal the vacuum's connection with your hand to make it air tight. 

If these don't seem to do the trick, and the water is still leaking, it is time to call a professional!
