Calculations to balance energy efficiency and noise reduction. How to Use the Tool
Keep the aspect ratio (width-to-height) between 1:1 and 1:4 to prevent excessive noise and pressure drops. Why Proper Sizing Matters

Undersized ducts force blowers to work harder, increasing power consumption.
Now maintained by Daikin Applied (which acquired McQuay), this tool is a favorite in the industry for its simplicity and accuracy. It helps designers determine: driving up project costs.
