The answer to 'ductwork making noise' is that there are several common causes for noisy ductwork, including loose connections, obstructions, and air leaks. Symptoms may include whistling, rattling, or banging sounds coming from the vents or ductwork. While some minor issues can be DIY-fixed, more complex problems often require a professional HVAC technician to diagnose and resolve the issue.
Loose connections in the ductwork can allow air to escape, creating whistling or rattling noises. Homeowners can try tightening duct connections and sealing any gaps with duct tape or mastic sealant. Obstructions like debris, furniture, or closed vents can also restrict airflow and cause noises. Clearing obstructions or adjusting airflow may resolve the issue. More serious problems like damaged ductwork, faulty blowers, or system imbalances often require professional HVAC services to properly inspect the system and make necessary repairs or adjustments.
