Birds and other small animals love dryer vents. They can build nests in the line causing serious clogs. You can discourage animals from claiming your dryer vent line as their new warm toasty home by installing the proper guard. Additionally, guards help to prevent back pressure from the outside wind in your dryer duct. Back pressure can cause carbon monoxide to enter your home. At Advanced, we offer both metal and plastic guards for installation depending on the homeowner’s goal and budget.
