Frequently Asked Questions

Your dryer needs to be able to breathe! The free flow of air through the entire venting system is absolutely necessary for proper performance. Dirty dryer vents cause longer drying times, which contribute to higher utility bills. In addition, loose lint can collect around the heating element and electrical wires. Excessively hot dryer loads caused by lint backup, in conjunction with the lint buildup surrounding the dryer’s heating element, increase the chance of a fire!

Every 6-12 months, depending on how much laundry you do. The NFPA (National Fire Protection Association) & most dryer manufacturers recommend that the dryer venting systems be inspected annually. Having your dryer vent system cleaned at least annually will help ensure that your dryer can operate more smoothly, lessening the risk of dryer performance issues and more importantly – lessening the risk of a fire caused by lint build up!

Besides expelling combustible lint from the dryer, now there exists a combustible gas which can produce carbon monoxide (A colorless, odorless & toxic gas). If the dryer vent is not maintained on a regular basis, the potential for carbon monoxide produced from the gas can leak back into your home causing sickness & potential death!

  • Improper construction of venting systems (improperly sealed vent joints, screws protruding through the vents, improper vent materials, damaged or missing exterior termination covers, excessively long dryer vent routes, etc.).
  • PVC piping. When air passes over plastic it generates static electricity. Lint is attracted towards the static, in turn creating thicker lint deposits within the dryer venting system.
  • Vinyl/plastic & flexible foil. These materials should never be used in dryer venting as they collect lint, water/mold, and increase your risk of a fire hazard. The ideal venting is rigid metal duct work which is solid with smooth interior walls.
  • Birds nests in the vent system
  • Wildlife intrusion

In many cases, dryer vent systems are in excess of 10 feet in length up to 35 ft in length. Many systems are hidden in the home’s construction and are inaccessible for proper maintenance unless you have the proper cleaning equipment & understanding of how the vent system is & should be constructed. Hiring a Certified Dryer Exhaust Technician dryersafety.org means that you’re trusting your family’s safety to someone who has spent countless hours & training understanding proper construction, inspection & maintenance of dryer vent systems that adhere to the related codes & standards.
