A Safe and Efficient Dryer Duct: What to Look For A Safe and Efficient Dryer Duct: What to Look For

An efficient dryer duct will save you both energy and money when it comes to the drying of your laundry. While there are many dryer duct options available, there are a couple of important things you should know before you make your purchase of one. Please read the important information below which will help you to choose a safe and efficient dryer duct, additional helpful safety information, and the amount you should expect to spend on the installation of the duct.

Types of Dryer Ducts

The standard dryer duct has a 4 inch diameter, though some are available with a 6 inch diameter. Most building codes require ducts be made of metal in order to prevent fire hazards and the best option is one that is smooth on the inside to prevent lint from sticking. Overall, rigid metal ducts provide cleaner air flow, are more durable, and are the safest choice. Flexible elbows can be used to round corners as necessary for the metal duct, but are generally not recommended for long stretches of length as they can clog easier. While vinyl, plastic, and the flexible foil ducts are available as well, they are not recommended because they deteriorate more rapidly, which can lead to undetected leaks and other hazards.

Important Safety Tips

Ensuring that your dryer duct is free of lint and debris build-up is important when it comes to preventing potential hazards. With that in mind, be sure to look for a dryer duct that is smooth on the inside as it is much easier to clean. You can clean your duct easily by inserting a vacuum hose into the opening of the duct. In general, rigid metal ducts are the easiest duct to clean as well as install. Another issue of concern has to do with what items are used when installing your dryer duct. For example, sheet-metal screws, rivets, or any other raised fasteners should not be used to connect the duct joints or be located near your duct. Fasteners extending into the airway catch lint and obstruct airflow. You should use clamps or foil duct tape to safely secure the joints. These two options are also easy to remove if necessary. 

Overall Expected Cost

Rigid metal dryer duct material is affordable, averaging around $30 for a 25 foot run, but can vary slightly from vendor to vendor.  Extra costs for elbows, duct tape, and any tools needed for installation should be anticipated, but are still not expensive. You could likely spend up to $75, which includes the material and extra tools you'll need for the installation of the entire dryer duct.
