Clearing vegetation around your outdoor AC unit is crucial for maintaining airflow and efficiency. The best approach is to ensure a clearance of at least 2-3 feet around the unit. Start by trimming any overgrown bushes, shrubs, or tree branches that encroach on this space. Use garden shears for smaller plants and a saw for thicker branches. Remove any loose debris, leaves, or grass clippings by hand or with a rake, and consider using a gentle stream from a garden hose to clear away dirt accumulated on the unit's exterior. Regular maintenance of the area prevents blockages and ensures optimal performance of your AC.
