4 duct problems Lake Oswego homeowners report after wet winters and heater season
The most common duct problems in Lake Oswego stem from damp winters, which raise indoor humidity and promote mold and musty odors inside ductwork, especially after the heater runs all season. Wet-weather infiltration and seasonal heating cycles also increase dust, allergens, and occasional metal corrosion in ducts.
- Mold and fungal growth. Damp winters in Lake Oswego raise interior humidity and feed mold inside ducts, producing visible growth near returns and persistent musty smells.
- Musty or earthy odors after heater season. Homes often report stale, damp smells when heating cycles disturb moisture-trapped debris, indicating biological growth or trapped moisture in duct insulation.
- Clogged filters and reduced airflow. Wet-airborne particulates and fibrous debris collect more readily during Lake Oswego's damp months, causing filters to load faster and lowering system airflow.
- Early metal corrosion and small air leaks. Persistent indoor humidity over winter can accelerate corrosion on sheet-metal ducts and joints in Lake Oswego homes, leading to leaks and reduced heating efficiency.
