The answer to 'dryer vent cleaning dirty' is that a dirty dryer vent is a common problem that can cause safety issues and reduce the efficiency of your dryer. Common causes include lint buildup, bird nests, and debris in the vent. Symptoms include longer drying times, a hot dryer exterior, and increased energy bills.
The solution is to regularly clean the dryer vent, either through DIY cleaning or by hiring a professional. DIY cleaning can be done by disconnecting the vent from the dryer, using a vent brush or compressed air to remove lint, and then reattaching the vent. However, if the vent is particularly long, has multiple turns, or is difficult to access, it's best to call a professional cleaning service to ensure the vent is thoroughly cleaned and any blockages are removed.
