To prepare your home for dryer vent cleaning, ensure clear access to both your dryer and the exterior vent. Remove any items or obstructions around these areas. It's helpful to run the dryer for a few minutes before the technician's arrival to warm the vent, which can loosen the lint and debris, making the cleaning process more efficient.

Dryer vents should typically be cleaned once a year, but this can vary based on your usage. Homes with higher laundry frequencies, such as those with large families or where the dryer is used daily, might need more frequent cleaning. Signs like longer drying times or the dryer becoming unusually hot can indicate it's time for a cleaning.

Yes, a clogged dryer vent can significantly impact your dryer's performance. Lint buildup in the vent can restrict airflow, causing the dryer to work harder and run longer to dry clothes. This not only leads to increased energy consumption but can also shorten the lifespan of your dryer due to the extra strain.

Flexible foil or plastic vents are more susceptible to clogging and kinking, which can restrict airflow more than rigid metal ducts. These types are also more vulnerable to the accumulation of lint and can pose a greater fire hazard. It's recommended to use smooth, rigid metal ducts where possible.

Immediate cleaning might be necessary if you notice an unexplained increase in drying times, excessive heat in the room where the dryer is located, or a burning smell during operation. These signs could indicate severe lint buildup in the vent, which poses a significant fire risk and should be addressed promptly.
