Hi,
Condensation happens normally when cold meets hot or vice versa.
Yes, it is normal because the humidity is high..........

The A/C system is designed to remove heat and humidity from the air entering the passenger compartment. The A/C evaporator, located in the HVAC housing, is cooled to temperatures near the freezing point. As warm damp air passes over the fins in the evaporator, moisture in the air condenses to water, dehumidifying the air. Condensation on the evaporator fins reduces the A/C evaporators' ability to absorb heat. During periods of high heat and humidity, an A/C system will be less effective. With the HVAC mode control set to RECIRC, only air from the passenger compartment passes through the A/C evaporator. As the passenger compartment air dehumidifies, A/C performance levels rise.

In addition, some models are equipped with an A/C system air filter. The filter is mounted under the hood in the outside-air intake (cowl, below the windshield) of the HVAC housing. The filter should be checked and replaced at least once every 15, 000 miles and checked if A/C-heater system performance seems lower than expected.

Yes, as the temperature outside gets hotter, condensation will build up and drip off the tube. This is due to the freon circulation that is contained in the A/C.

    Chris is incorrect, although you are not using the A/C, the compressor is still turning, due to the belt on it and the unit is designed to circulate the freon tht is in the unit, otherwise it would freze the unit and the compressor would be damaged.
