Fans on the ceiling have certainly added to the comfort of the home not only in the living room and bedroom but most certainly in the kitchen. When it is just too cool to turn on the air conditioner but too warm to be without some cool air the ceiling fan is the answer.
Ceiling fans with ceiling light are good for keeping the room cool and light without turning on the big lights which would only defeat the cooling purpose
These are secondary uses and surely you can find a few of your own secondary uses for the fan. The kitchen fan serves more purposes other than just keeping the room cool.
When the kitchen has been painted or the floors have been freshly cleaned the fan can be used to dissipate the smell of the paint and hasten its drying and as for the floors they too will dry quicker when the fan is turned on.
Ceiling fans with lights are a convenience for when you want more light as its light will add to what is in the room. The lights also serve to contribute light to a room when you want only some light and not a lot of light.
