1. Filter Cleaning or Replacement:
- Inspect and clean or replace air filters regularly to remove dirt, dust, and other contaminants that can obstruct airflow.
- Clean filters according to the manufacturer's recommendations to maintain proper airflow and prevent filter damage.
2. Coil Cleaning:
- Clean the evaporator and condenser coils to remove dirt, dust, and debris buildup that can reduce heat transfer efficiency.
- Use a soft brush or vacuum cleaner with a soft brush attachment to clean the coils.
- Avoid using harsh chemicals or high-pressure water that can damage the coil fins.
3. Drain Pan Cleaning:
- Inspect and clean the drain pan to remove any dirt or debris that could block the condensate drain.
- Ensure that the drain pan is properly sloped to allow for proper drainage.
- Clean the drain line to prevent clogs and ensure proper drainage.
4. Blower Motor Maintenance:
- Inspect the blower motor for any signs of wear, damage, or unusual noises.
- Check the motor bearings and lubricate them according to the manufacturer's recommendations.
- Ensure the motor is securely mounted and properly aligned to prevent vibration.
5. Fan Blade Cleaning:
- Clean the fan blades to remove any dust or dirt accumulation that could affect airflow.
- Use a soft cloth or brush to clean the fan blades.
6. Duct Cleaning:
- Inspect and clean the air ducts to remove any dust, debris, or blockages that could restrict airflow.
- Use a vacuum cleaner or duct cleaning equipment to clean the ducts thoroughly.
7. Controls Inspection:
- Inspect the air handling unit's controls, including thermostats, sensors, and actuators, to ensure proper operation.
- Calibrate controls as necessary to maintain accurate temperature and humidity levels.
8. Belt Inspection and Replacement:
- Inspect the belts that drive the fan and blower motor for signs of wear or damage.
- Replace belts that are cracked, frayed, or excessively stretched.
9. Leakage Inspection:
- Inspect the air handling unit for any air leakage that could affect its performance.
- Seal any gaps or cracks to minimize air leakage and maintain desired airflow.
10. Sound and Vibration Monitoring:
- Monitor the sound and vibration levels of the air handling unit to ensure it operates smoothly and quietly.
- Address any excessive noise or vibration to maintain a comfortable environment.
11. Maintenance Records:
- Keep detailed maintenance records, including the services performed, dates, and any observations.
- Refer to maintenance records to track service intervals and identify any trends or issues.
Regular servicing and maintenance of the air side components of an air handling unit are essential to ensure efficient operation, optimal air quality, and a comfortable indoor environment.
