At my house I use a replacement bathroom ventilation assembly from Larson Fan Company that has a true damper built-in. The damper feature keeps warm air in during the winter and hot, humid air out during the summer, and has reduced my annual energy bills by over ten percent. Since cooling takes more energy than heating, our products save more during the summer. You can find more about our replacement fan assemblies at larsonfan.com.
