Standard procedure on dryer vents has changed over time and if you still have a 4 inch white plastic or even aluminum foil exhaust duct, you might consider replacing it for energy efficiency. If you are moving your dryer, buying a new one or simply looking for ways to make your home more efficient, dryer vent replacement is a good start.
The spiraled wire interior is not insulated well, so it does not maximize dryer heat and lets out hot air. It also has a ribbed interior that disrupts the airflow and allows dryer lint to stick, further inhibiting the flow of air. The plastic tubing is a fire hazard and no longer permitted in building and construction.
A dryer vent rerouting or replacement requires complying with building code and International Residential Code (IRC) guidelines, and there are other governing agencies that take a strong stance on hiring a professional to do the job. The National Fire Protection Association (NFPA) and Chimney Safety Institute of America (CSIA) have taken strong stances and created inspection criteria to make homes safer from dryer vent fires.
