Because the original desktop software was developed for Windows, Mac users have two primary options:
Wine is a compatibility layer capable of running Windows applications on macOS without requiring a full Windows operating system license.
Once the installation process finishes, select the path to the main .exe file so the app knows what to launch.
Developed by McQuay (now Daikin), the Duct Sizer is a free, indispensable software tool designed to calculate: Friction loss per 100 feet/meters Velocity Duct Dimensions (Height & Width/Diameter) mcquay duct sizer for mac
While McQuay Duct Sizer is a powerful tool, it's not the only game in town. For Mac users who are looking for alternative duct sizing solutions, here are a few options:
Poorly sized ducts can cause major problems. Undersized ducts increase static pressure and noise, while oversized ducts waste material and reduce velocity, leading to poor ventilation.
: Sometimes, software engineers or architects share solutions or workarounds on professional forums or LinkedIn groups. These can be great places to ask for advice. Because the original desktop software was developed for
Use software like Parallels Desktop, VMware Fusion, or VirtualBox to run the original Windows-based McQuay software.
Sizes the duct system by maintaining a constant pressure drop per unit length of duct (e.g., 0.1 inches of water gauge per 100 feet).
Proper duct sizing is critical for an effective HVAC system. It directly impacts many key factors: For Mac users who are looking for alternative
Given that the McQuay Duct Sizer is legacy software (last updated circa early 2010s), many Mac engineers have moved to modern, cloud-based or cross-platform duct sizers. Consider these instead:
Set the friction loss per 100 feet (0.1 is common, 0.05 is often used for quieter systems).
If you prefer to avoid virtual machines and emulation entirely, several native macOS tools and web-based applications offer identical duct-sizing functionality. 1. Web-Based Duct Calculators
