Yeah, what most people don't know is that AC is a great dehumidifier along with cooling. The air gets pretty cold right when it passes over the coils. Cold air holds less water, so a lot of humidity drops out as condensate. A lot of cooling power is actually consumed by the vapor->liquid transition of water in the air. This is why it's very important to have a well sealed house when using heat pumps/ac. Letting more water vapor in is just as bad as letting in warmerr air. Once the humidity is lowered the AC unit doesn't work nearly as hard to cool air The cold feeling is two fold. The lower humidity helps almost as much as the temperature drop in humid areas. Heating doesn't cause the water vapor phase transition so sealing out humid air matters little for efficiency. This is why many older buildings have higher cooling than heating costs. Sealing is just as important as insulation when cooling
