1. Inspection and System Evaluation

HALO HVAC begins with a thorough inspection of the AHU to assess its overall condition. This includes checking for unusual noises, vibrations, and leaks that may indicate wear and tear or malfunctioning components.

2. Filter Replacement and Cleaning

Filters are crucial for maintaining indoor air quality. Technicians replace or clean filters to ensure optimal airflow and prevent dust and debris buildup, which can reduce efficiency and increase energy consumption.

3. Coil Cleaning and Maintenance

Evaporator and condenser coils accumulate dirt over time, reducing heat exchange efficiency. HALO HVAC cleans the coils using specialized cleaning agents to restore performance and prevent system strain.

4. Fan and Motor Inspection

The fan and motor assembly are checked for signs of wear, imbalance, or misalignment. Bearings are lubricated, and belts are adjusted or replaced if necessary to maintain smooth operation.

5. Dampers and Actuators Testing

Dampers control airflow within the AHU. Technicians test their operation and adjust or repair actuators to ensure proper modulation, preventing airflow restrictions or energy wastage.

6. Drainage System and Condensate Line Maintenance

Clogged condensate drains can cause water leaks and humidity issues. The drainage system is inspected, and any blockages are cleared to prevent water buildup and potential mold growth.

7. Electrical Component Inspection

All electrical connections, wiring, and controls are examined for signs of wear or damage. Loose connections are tightened, and faulty components are repaired or replaced to avoid electrical failures.

8. Sensor and Control Calibration

Temperature, humidity, and pressure sensors are tested and recalibrated to ensure accurate readings, allowing the AHU to function efficiently in maintaining desired environmental conditions.

9. Ductwork Inspection and Cleaning

Ductwork is inspected for leaks, obstructions, or contamination. Cleaning is performed if necessary to maintain air quality and system efficiency.

10. Final Testing and Performance Optimization

After completing maintenance tasks, the AHU is tested to verify optimal performance. Airflow, temperature, and pressure settings are adjusted to ensure efficient operation and energy savings.

By following these maintenance procedures, HALO HVAC ensures that air handling units operate at peak efficiency, reducing downtime, extending equipment lifespan, and improving indoor air quality.
