PLUS your motor should last much longer and you won't have that blast of hot air during the summer every time the compressor starts.

Most systems installed by the builder do not have a true dehumidifier setting, so there is no reheat function. They are designed to lower the temperature by about 3 degrees to reduce the humidity, but the compromise is that your house gets colder than the thermostat setting. There is no reheat. That is why I do not use the humidity setting.
The humidity setting can be used by snowbirds to save electricity by setting the thermostat a few degrees higher, and still keep the humidity down when it is needed.
