Water droping Dear Sir! My air conditioner, is dropping water. Why and how to fix it?

Your drain pan is not draining. Use a wet vac to **** the drain line from the outside. This will pull out the blockage and you're back in business. Do not blow compressed air into the drain. This pushes the blockage back up into the drain pan.

Why? Because as the air passes over the coil and is cooled, the humidity in the air condenses and drains into the drain pan. When the drain line or pan gets clogged, it no longer drains to the outside. That causes the pan to overflow, and drip into the house.

How to fix it? You will need to locate the drain line and remove the clog. This is easiest done with a wet/dry shop vacuum.
