Attic fans do help, but only if they are installed properly and used in the right way. If you have an attic fan, it's important to use it in conjunction with roof vents to create a cross-ventilation system. This will allow air to flow through your attic and keep it cool. If your attic fan is installed improperly or if you don't use it in conjunction with roof vents, it can actually do more harm than good. The fan can pull hot air out of your house and cause your cooling system to work harder, which can lead to higher energy bills.

Yes, attic fans really help. They work by drawing in cooler air from the outside and push the hot air out of the attic. This can help to reduce your energy bill by cooling your home down. It is important to note that not all attic fans are created equal, so be sure to do your research before purchasing one..
