2. What is Air Balancing?
• Measures performance of HVAC system
– Test and adjust system to deliver correct air flow to
each space
• Compare design air flow to actual measured air
flow
– Supply and return openings, exhaust and ventilation
• Air flow hoods can be used to test grills/vents
• Traverse readings taken to find air flow inside
ducts

3. Traverse Readings
• Series of air velocity readings taken in a grid
pattern across a duct to find average air
velocity

4. How to take Traverse Readings
1. Drill the test holes
2. Insert probe and record velocity
3. Find the average velocity of readings
4. Multiply the average velocity by area of duct
to find air flow in CFM
