5. Clean the Condenser Unit Base

Inspect the base of the condenser unit for any debris or blockages. Remove any obstructions to ensure proper drainage and airflow.

Use a screwdriver to tighten any loose electrical connections. Inspect the wires for any damage or fraying. If you notice any issues, contact a qualified electrician.

7. Vacuum the Unit (Optional)

For a more thorough cleaning, you can use a vacuum cleaner with a soft brush attachment to remove any remaining dust or debris from the unit’s exterior.
