Dryer Vent Maintenance in Peoria, AZ

Why does one load take three cycles to dry?

Almost always the duct, not the dryer. Peoria runs are usually attic-to-roof-jack verticals, 12 to 25 feet, with one or two 90s. Lint settles in the elbows first. Then desert dust pulled back through the cap during haboobs binds into that lint. The result is a dense mat, not fluffy fuzz. A shop vac at the wall will not touch it. Rotary brushing from both ends does.

Check the roof cap or hood yourself while a load runs. No visible airflow means the run is packed. Laundry room over 90F during use is one tell. A burning smell is another. The dryer may also trip its thermal limit. Gas dryers add a real backdraft concern, since a blocked run has to push combustion byproducts somewhere.

Two local failures repeat. Flex duct crushed flat behind pedestal washer and dryer sets in shallow laundry closets. Foil duct collapsed where it crosses a truss chord in the attic. Spring brings house sparrows and finches nesting in roof jacks, and bees in wall-cap terminations.

Frequency: yearly for a standard 15-25 ft attic run. Every 6 to 9 months with pets or a big family. Pool towels year-round push it further. Short exterior-wall runs in older slab ranches can stretch to 12-18 months.
