You have probably noticed that your laundry room is always colder than every other room in your house. Ever stopped to wonder why? Your clothes dryer is connected to a 4 inch diameter duct used for exhaust. During the winter months cold air leaks in through unsealed locations where this duct meets the exterior of your home, through the duct itself, and even through the dryer while the air you pay to heat slips right outside.
Go outside on a cold day and put your hand by the dryer vent. You can feel the warm air leaking out and it represents a substantial loss of energy. On top of that, many discharge vents use a primitive sheet metal flapper to try and prevent air leakage. These devices do not make a very good seal to stop escaping and air, and are also prone to staying open when they cog with lint from the dyer. It can be comparable to leaving a window open! Making matters worse, during the summer months your dryer vent is likely letting hot air in.
