A » Whistling noises in HVAC airflow often arise from issues such as improperly sized ducts, blocked vents, or dirty filters. These problems cause air to move at high speeds through restricted openings, creating a whistling sound. To resolve this, ensure ducts are correctly sized, clean filters regularly, and keep vents unobstructed. Consulting an HVAC professional can help identify and rectify the cause of the noise efficiently.
