Not heating, pollen lint vent blockage — Same-day, fixed quote.
Dunwoody dryer repair has the most distinctive seasonal pattern in the GA-400 corridor — two separate and predictable annual blockage windows driven by the city's defining characteristic: its mature, dense tree canopy. Dunwoody's original development from the 1970s planted trees that are now 40–50 years old and producing significantly more debris than the younger canopy in Alpharetta or Johns Creek. Spring pine and oak pollen from mid-March through May loads exterior vent flaps at volumes that exceed younger-canopy neighborhoods. October through December, the same mature trees drop substantial leaf volume that accumulates on vent terminations at rates that newer suburban communities don't experience.
40–50 year old trees — Dunwoody's canopy produces most severe pollen and leaf debris in corridor
Predictable annual blockage windows — spring pollen and fall leaves both significant here
Unlike newer GA-400 communities where spring pollen is the primary annual vent blockage event, Dunwoody generates near-equal blockage risk from both spring pollen and fall leaf accumulation. The mature oak and hardwood canopy over Georgetown, Dunwoody Village, and Perimeter neighborhoods produces a fall leaf drop that can completely block exterior vent flaps within weeks of peak leaf fall. We recommend twice-annual vent assessment for Dunwoody properties in dense canopy areas — spring (April) and fall (November) — rather than the standard annual interval.
Dunwoody's 1975–1990 homes have laundry rooms with dryer vent paths established during original construction — direct exterior wall exits in standard positions that have been maintained across multiple dryer generations. These configurations are straightforward to assess but may have 40-year-old duct materials behind walls that warrant attention if restriction persists after vent flap cleaning.
