HVAC baffles are an important component of any heating, ventilation, and air conditioning (HVAC) system. They are used to control air flow, reduce noise, and improve the efficiency of the system. Baffles are typically made of metal or plastic and are designed to fit within the ductwork of the HVAC system. They are usually placed at the beginning of the ductwork and are designed to control the direction of the air flow. By redirecting the air flow, the baffles can help to reduce noise and improve the efficiency of the system. Additionally, baffles can help to reduce the amount of dust and other airborne particles that enter the HVAC system. This can help to improve the air quality in the home or business. HVAC baffles are an important part of any HVAC system and should be installed properly to ensure optimal performance.
