It's recommended to clean your dryer vent at least once a year. However, if you use your dryer very frequently, have a large family, or have pets that shed a lot, you may need to clean it more often.

Look for longer drying times, the dryer becoming excessively hot, a noticeable musty odor, visible lint accumulation outside the vent, or a burning smell during operation.

While it's possible to do basic lint removal yourself, professional cleaning is recommended. Professionals have the necessary tools and expertise to thoroughly clean the vent and identify any potential issues.

Common repair needs include fixing disconnected or damaged vent ducts, replacing crushed or kinked hoses, and repairing or replacing exterior vent covers.

Rerouting may be necessary if you're experiencing persistent problems like mold growth, extended drying times, or if the current vent path is too long or has too many turns. Rerouting is also considered during home renovations or appliance relocations.
