Dryer Vent Maintenance in La Mesa, CA

How often does a dryer vent actually need cleaning in La Mesa?

Depends on the run, not the calendar. Short 4–8 ft through-wall runs from garage laundry corners in postwar ranches stay clean longer. Every 18–24 months is usually enough there. Vertical second-floor-to-roof runs in 1980s–2000s two-story tract and townhome stock are different. Those want annual service. So do interior hall closet runs with 15–30 ft of attic duct and two to four elbows. Pets or a large family? Annual, regardless of run.

Lint is only half the story here. Roof caps and exterior hoods also collect wind-driven dust and jacaranda, eucalyptus and oak pollen. Birds and wasps nest in hoods during the long dry season. A screened cap is the worst offender. Lint mats against the mesh from inside, pollen cakes it from outside.

Check your own duct before calling anyone. Pull the dryer out. Look for flex crushed flat behind a pedestal or stacked unit. Foil or plastic duct sagging into a belly is a moisture trap and a disconnect waiting to happen. In the attic, a popped joint dumps warm lint onto insulation.

Two or three cycles for towels and jeans, a hot laundry closet, or a burnt-dust smell means it's already past due.
