A HVAC Baffle Box is a device used in air conditioning and heating systems to control the flow of air. It is typically a box-like structure with a series of baffles, or small plates, inside. The baffles are designed to direct the air in a specific direction and help regulate the temperature of the air. The box is usually made of metal or plastic and is connected to the ductwork of the HVAC system. The box helps to ensure that the air is evenly distributed throughout the home, which helps to improve energy efficiency. The baffles also help to reduce noise from the HVAC system, making it more comfortable for the occupants of the home. HVAC Baffle Boxes are an important part of any HVAC system and should be inspected regularly to ensure they are functioning properly.
