Why does the air condition drip a lot on some days on my car?
Cmundley asked:
On some days it drips a lot of water on the ground while its running, then on other days it doesn’t seem to drip much at all. Its a 2009 Chevy Tahoe, so everything should be working fine on it.

has to do w/ humidity and the condensor pulling that humidity out of the air…

Because your breath smells like DoDo

the dripping is condensation
the more humid it is outside, the more condensation, given the outside temperature is higher than the air conditioning unit’s temperature

Nothing to worry about. It’s just dripping more on days when the humidity is higher. Just like a cold drink does on a table, your condenser sweats because it is ice cold, and the water runs out under your vehicle.

Your right, there is nothing wrong with your vehicle, this is normal. If you have a glass of cold drink with a lot of ice in it and leave it a while then there will be a lot of water on the outside of the glass, in fact you probably will need a coaster to catch all this or at least a napkin under it. If you leave it the same outside on a humid day it will condensate even more water since an air with more humidity in it would be coming in contact with the outside surface of the cold glass, right?
In your air conditioning system you have the same thing, a very cold surface with air blowing across it to cool the air. The ambient air will have varied humidity to it from day to day thus having more for the cold surface to condensate out of the contacting air! Just as the cold glass does. This part inside your dash of your vehicle coming in contact with the air is called the evaporator because it takes liquid refrigerant (r134a) from a liquid form inside and evaporates the freon to a gaseous state making the outside surface very cold to cool the air blowing across it and condensing water from the outside air.
Hope this helps…

The system prior to entry into the vehicle is ice cold the lines form ice on the exterior and the ambiant(surrounding) air temperature and humidity makes it form and melt accordingly.

It drips more on humid days.
