There are several reasons an A/C may drip.
One in very humid weather the cold air coming out the outlets meats the warm moist air around them and condensation happens. And Drip Drip Drip
Two There is a gasket between the A/C and the roof, may need attention or replacement (Very simple job)
Three: I have found when the intake filters get dirty the blower will SUCK water out of the drip tray and eventually it drips drips drips. NOTE when you turn the blower off .. NIAGRA FALLS
Icing on the evaporator coils
Dirt in the normal water path
And yes Out of level.
the problem one;... Cracked drip tray. heard of one, never seen one.
