Keeping floor vents clean and functional throughout the year supports better airflow and home efficiency. In spring, remove dust, allergens, and debris to reset your system after winter. Summer maintenance involves keeping vents clear of furniture and ensuring airflow is directed effectively. During fall, inspect for rust, tighten any loose covers, and clean ducts for improved air quality. In winter, check for moisture, wipe away condensation, and seal any gaps to prevent heat loss. Regular seasonal care not only extends the life of your vents but also helps maintain a healthier and more comfortable indoor environment.
