Inadequate air draft is a common problem with barometric dampers.

Inadequate air draft being a common problem with barometric dampers is indeed true. Barometric dampers are designed to regulate air pressure and facilitate proper draft in vent systems, particularly for gas appliances. When these dampers fail to operate correctly, often due to improper installation, misalignment, or mechanical failure, they can restrict the airflow needed for adequate draft. This can lead to combustion efficiency issues, increased emissions, and potentially dangerous situations such as backdrafting, where combustion gases are pushed back into the living space instead of venting outside. Proper functioning of barometric dampers is essential for maintaining the right balance of air pressure and ensuring the safety and efficiency of HVAC systems.
