Should My Attic Have A Fan. Additionally the attic fan will create negative pressure in your attic that will draw the cool air conditioned air from your living space through leaks which virtually all houses have. Additionally when an AC unit doesnt have.
As attic fans draw in fresh air they also pull in moisture and dry it out. Your article does a great job of outlining how this happens. Because typically attic fans are so strong that not only do they take the hot air out of the attic but they reach down into your house and take the cool air out of the house as well.
But my question is regarding a replacement attic fan versus the ridge vent.
Lower energy bills when not working in tandem with your air conditioner. Now if you did have central air conditioning I would tell you not to install an attic fan and heres why. Some can move almost 300000 cubic feet of air. A whole-house fan is designed to pull air in through open windows and doors and exhaust this air through an attic space to the great outdoors.
