Air balancing is the testing and adjusting HVAC systems to deliver the right amount of air to each area of a building. To determine the performance of your air conditioning and heating system air balancing hoods are used to measure the amount of air at each air register. Manometers then measure system pressure. Hygrometers can be used to measure system temperature and humidity. The results of the tests are used to determine how well your HVAC system is working.
By understanding which sections of a building have positive and negative airflow, steps can be taken to ensure that the air delivery system is properly configured to ensure that the heating and cooling system is able to operate as efficiently as possible to ensure that the air is properly balanced throughout the building.
