- Maintaining proper airflow: Ensures efficient ventilation and temperature regulation.
- Protecting against debris: Prevents leaves and branches from clogging vents.
- Saving energy costs: Supports energy-efficient heating and cooling.
- Preventing mold growth: Reduces moisture buildup that leads to mold or mildew.
