The problem that you have indicated in your post is pertaining to Evaporators that is used in car airconditioning.
The evaporator is very similar in function to the heater core, except for the fact that it absorbs heat from the passenger compartment instead of supply heat. It is usually mounted under the passenger side dash and mounted to the inside firewall. The low-pressure liquid refrigerant enters the bottom of the evaporator, or a high-pressure liquid that is sprayed into the evaporator by the expansion valve, goes through a rapid evaporation and changes state into a vapor. Its primary duty is to remove heat from the inside of your vehicle but the secondary benefit is dehumidification.
Just as water condenses on an ice filled glass, water condenses on the evaporator. Airborne contaminants entering the system stick to the wet evaporator and are drained to the outside. Temperature and pressure regulating devices must be used to control its temperature. While there are many variations of devices used, their main functions are the same, keeping pressure in the evaporator low and to keep the evaporator from freezing.
Your Mechanic is right. The evaporator drain has been clogged or the flexible pipe running from evaporator to outside car is loosen or not present at all. Its a petty job and any AC Mechanic can do it for you.
