Air is moved through ducts to reach the various HVAC system components. Good ducting is essential for delivering high-quality air to the area. Duct leakage can cause noise while the system is working.
Also, when the air ducting is not in good condition, odors and excess moisture can fill the air. Air is delivered to the rooms, passings through the vents. Vents can be equipped with air filters to prevent dust and small particles from entering the room. Air filters can also be installed elsewhere inside the ducting.
