Dryer Vent Cleaning and AF Error Fix — Mountain View

Our client Travis from Mountain View reached out to us with an issue that often goes unnoticed until it causes serious problems. His dryer began displaying the error code “AF.”

✅ What this meant:

The “AF” code indicates poor ventilation. The vent duct was partially clogged with lint, dust, and debris, which blocked the proper airflow.

As a result:

• Drying cycles took much longer;
• Clothes remained damp even after the program finished;
• The risk of overheating and even fire increased.

We carried out a full diagnostic and resolved the issue.

✅ What was done:

• Ventilation system inspection: We checked the large-diameter metal duct that runs along the ceiling. This section turned out to be the most problematic.
• Work difficulty: The duct was positioned high near the ceiling, making self-cleaning nearly impossible. Special tools, extended brushes, and experience working at height were required. That’s why such tasks are effectively handled by our technicians.
• Cleaning: We removed lint, dust, and debris, restoring proper airflow.

Now the dryer is running efficiently and safely again!

❓ Why is it important to clean the dryer’s ventilation system?

✅ Regular cleaning reduces strain on the motor.
✅ It lowers energy consumption.
✅ Extends the lifespan of the dryer.
✅ Reduces the risk of fire.

❓ How to know when your vent needs cleaning?

✅ Drying time increases.
✅ Clothes stay damp.
✅ Burning or musty odor appears.
✅ The dryer’s exterior gets unusually hot.
✅ Error codes like “AF” appear.

❓ What preventive measures are recommended?

✅ Schedule vent cleaning at least once every 6–12 months.
✅ For large families or daily use, inspections should be done more often.
✅ Use rigid metal ducts instead of plastic or flexible ones, as they clog more easily.

Now Travis from Mountain View has his dryer working reliably and safely again, with the added peace of mind that even the difficult ceiling-level duct was professionally cleaned by our technicians.
