The idea of humidity control from a/c in SF only occurs when the a/c operates long enough to saturate the cooling coil and pan, actually exiting via the drain. At the end of the cooling cycle, any moisture on the coil and pan evaporates back into the home. There is typically 1-2 lbs. on moisture on the coil at the end of the cooling cycle. This require a minimum of 30 minutes of high speed cooling on most coils get any water exiting the pan. Get dehumidification in writting. There is an improvement moisture removal during moderate cooling loads but very little in the cool wet weather.
