It is typically made of metal and is designed to protect the components from the elements, as well as provide a secure place for them to be stored. The cabinet also helps to reduce noise levels and keep the system running efficiently. It is important to keep the cabinet clean and free of debris to ensure that the system is running properly. The cabinet also helps to reduce energy costs by providing insulation and preventing heat loss. The HVAC cabinet is an integral part of any HVAC system and should be regularly maintained to ensure that it is functioning properly.
