Does fan speed matter in AC?
In general, the slower the air speed, the better the cooling since the air spends more time on the evaporator. The tendency is to use the highest speed, to get a higher volume, but that will result in a less colder air.
What speed should my AC fan be on?

Is higher fan speed better?
Set the fan speed on high, except on very humid days. When humidity is high, set the fan speed on low for more comfort. The low speed on humid days will cool your home more effectively and remove more moisture from the air because of slower air movement through the cooling equipment.
