What is VAV’s?

VAV stands for Variable Air Volume. A VAV system is a type of HVAC (Heating, Ventilation, and Air Conditioning) system that varies the amount of air supplied to a space to control the temperature. Instead of supplying a constant volume of air at a variable temperature, VAV systems supply a variable volume of air at a relatively constant temperature. This is typically achieved using a VAV box which modulates airflow into a zone based on a thermostat's call for heating or cooling. VAV systems are commonly used in commercial buildings and other large spaces because they can be more energy-efficient than constant volume systems, especially in spaces with varying occupancy levels or heat loads.
