AHU Troubleshooting - Common Issues and Solutions

Like any mechanical system, AHUs can experience issues that impact their performance. In this article, we will discuss common AHU issues and provide solutions to address these challenges effectively.

AHU troubleshooting

1. Insufficient Airflow

Issue: Inadequate airflow can result from clogged filters, malfunctioning fans, or blocked ducts. Insufficient airflow leads to poor ventilation, uncomfortable indoor temperatures, and compromised air quality.

Solution: Regularly inspect and replace air filters, ensuring they are clean and free from debris. Check the fan motor and blades for damage or wear, and clean ducts to remove any obstructions.

2. Uneven Temperatures

Issue: Uneven temperatures in different parts of a building indicate poor distribution of conditioned air. This can result from imbalanced ductwork, closed dampers, or improperly configured VAV systems.

Solution: Ensure dampers are properly adjusted to balance airflow and verify that VAV systems are calibrated correctly. Conduct a ductwork inspection to identify any restrictions or obstructions that may affect airflow distribution.

3. Excessive Noise

Issue: Noisy AHUs can be disruptive and indicate issues with fan blades, belts, or bearings. Excessive noise can impact occupant comfort and overall well-being.

Solution: Regularly inspect and lubricate fan components, ensuring that belts are properly tensioned. If noise persists, consider adding vibration isolation measures to reduce operational vibrations and noise transmission.

4. Poor Indoor Air Quality

Issue: Diminished indoor air quality can result from inadequate filtration, contaminated coils, or leaks in the ductwork, leading to discomfort and health concerns.

Solution: Install high-quality air filters and regularly replace them to ensure efficient particle and allergen removal. Schedule routine coil cleaning to prevent mould and bacteria buildup. Inspect ductwork for leaks and seal any gaps to prevent contaminants from entering.

5. High Energy Consumption

Issue: High energy consumption can indicate inefficient AHU operation, often resulting from improper fan speed settings, leaky ducts, or failing components.

Solution: Implement energy-efficient practices such as using variable frequency drives (VFDs) to adjust fan speeds based on demand. Regularly inspect ductwork for leaks and seal them to prevent air loss. Conduct regular maintenance to identify and replace worn-out components that may contribute to energy waste.
