Traditionally fans use angled blades in a counter clockwise spin to push air down making the room feeling cooler. However during the winter warm air will accumulate near the ceiling, you know the old rule warm air rises… Changing the rotation of your room’s fan can help to draw the colder air that has settled near the floor to be brought up to the ceiling in the process pushing warm air back down to the floor. You may be wondering how does this help to cut heating cost. Well for one, you won’t be turning that heat up because the room will feel warmer but also because most thermostats are typically located at human level. This means that the lower warm air will prevent your thermostat from kicking on the furnace and it allows you to keep it a few degrees lower.
