1. Clean or replace filters: For air conditioners, check filters monthly and clean or replace them every 1-3 months. For fans, wipe down blades and grills regularly to prevent dust buildup.

2. Inspect coils: Clean the evaporator and condenser coils of your AC at least once a year for optimal efficiency.

3. Check drain lines: Ensure the condensate drain of your AC is clear to prevent water damage and mold growth.

4. Tighten loose screws: For fans, check and tighten any loose screws to reduce noise and improve stability.

5. Lubricate motor: If your fan has a motor that requires lubrication, apply oil as needed.

6. Schedule professional servicing: Have a technician inspect your AC annually to keep it running smoothly.

7. Store properly: When not in use, store fans in a dry place to protect them from moisture.

With these simple maintenance tips, you can ensure your cooling appliances work efficiently all summer long!
