HVAC Duct Cleaning in Bodega Bay, CA

Why coastal duct systems load up here

Marine air does most of the damage. Cold supply duct sweats in humid west-county conditions. Condensation wets dust, and dust becomes a mat. On older galvanized trunk-and-branch under raised foundations, the original wrap breaks down first. Then crawlspace moisture reaches bare metal. Mold on cold supply duct follows that sequence, not a filter mistake.

Attic flex from 1980s tract construction fails differently. It sags between hangers. It kinks at tight turns. Storage boxes crush runs flat. Airflow drops, the blower works harder, and debris settles in the low spots instead of moving.

Crawlspace runs take the worst of it. Crushed duct and disconnected boots dump conditioned air under the floor. Rodents nest in that cavity and drag insulation into the trunk. That is contamination, not dust, and cleaning alone does not fix it.

We inspect before quoting. Return plenums and filter slots in older tract homes are often undersized or leaking, pulling crawlspace and attic air straight into supply. Sealing that matters more than brushing branches. Inland homes commonly go three to five years between cleanings. Move it up after fire smoke, a remodel with drywall dust, rodent intrusion, or any standing-water episode. Spring grass and oak pollen accelerate loading too.
