While there is no official "McQuay Duct Sizer for Mac" application released by McQuay (now Daikin Applied), macOS users can run this classic HVAC tool by using the HVAC Duct Sizer app from Carmel Software Corporation available on the Mac App Store. Running McQuay-Style Sizing on a Mac
The original McQuay Duct Sizer was a Windows-based lightweight executable (.exe). To use similar functionality on a modern Mac, you have three primary options:
App Store Version: The HVAC Duct Sizer app is officially compatible with macOS 12.5 or later and requires a Mac with an Apple M1 chip or later.
Virtualization: For older Intel-based Macs or those wanting the exact legacy Windows interface, you can run the original McQuay .exe file using Wineskin Winery or Parallels Desktop.
Official Mobile Versions: The tool is available for iOS (iPhone/iPad) and Android. Key Features of the Tool
Whether using the legacy version or the modern Mac App Store alternative, these tools simplify the equal friction and velocity methods of duct design:
Inputs: Specify airflow in CFM or L/s, and choose either a friction loss limit or a velocity limit.
Calculations: The software automatically determines the equivalent diameter for round ducts and provides rectangular dimensions based on your preferred aspect ratio.
Aspect Ratio Control: It helps maintain proper ratios (ideally 1:1, maximum 4:1) to prevent excessive noise and head loss. Units: Supports both Imperial (IP) and Metric (SI) units. Recommended Alternatives for Mac
If you prefer a native macOS experience beyond the App Store port, consider these alternatives: MCQUAY Duct Sizer Explained: Easy Duct Sizing for Beginners
Once upon a time in the world of high-stakes HVAC design, a seasoned engineer named Elias found himself facing a modern-day dilemma. He had recently traded his clunky old PC for a sleek, aluminum-bodied MacBook, only to realize that his most trusted companion—the McQuay Duct Sizer—was a Windows-native dinosaur. The Dilemma of the Mac Transition
Elias stared at his vibrant Retina display, missing the familiar, grey interface of the software that had calculated his friction losses and air velocities for a decade. The Ultimate Guide to McQuay Duct Sizer for
He missed the "Equal Friction" and "Equal Velocity" methods that lived in the McQuay menus.
His project—a high-end office building—demanded precision to keep the noise below 1500 fpm.
Without the tool, he was stuck with manual charts, and he knew that undersized ducts were the fastest way to a high utility bill and a disgruntled client. The Workaround
Elias wasn't ready to give up his Mac. He spent a rainy afternoon scouring forums and found the digital path forward:
Virtual Machines: He installed Parallels Desktop to run a Windows environment right on his macOS.
Emulation: He experimented with Wine to see if the McQuay executable would "bridge the gap" without a full OS install.
Mobile Synergy: He discovered the HVAC Duct Sizer app on the App Store, which felt like a "digital Ductulator" in his pocket for quick site visits. The New Standard
By the time the office project reached the construction phase, Elias had mastered his hybrid workflow. He could calculate CFM on his Mac, verify the equivalent diameter on his iPhone, and produce a design so silent that the librarians in the building across the street were jealous. Duct Sizing Step By Step With McQuay Duct Sizer
Wine (Wine Is Not an Emulator) translates Windows API calls to macOS POSIX calls. Because the Duct Sizer is a simple, old program, it runs flawlessly under Wine.
Note: On Apple Silicon (M1/M2/M3 Macs), Wine requires Rosetta 2 translation. This works, but you may need the wine-devel or wine-crossover builds.
Product Overview The McQuay Duct Sizer is a professional-grade HVAC engineering tool designed to calculate optimal ductwork dimensions based on airflow, velocity, and friction loss. Originally a staple of the Windows environment, specific versions or workflows are required to run this utility natively on Apple macOS.

Support Statement McQuay/Daikin Applied does not provide technical support for running their Duct Sizer on macOS. This guide is community-sourced for professional HVAC engineers.
Bottom Line: McQuay Duct Sizer is not native to Mac, but it works perfectly via Wine (Intel Macs) or UTM/Parallels (Apple Silicon) . For friction-only quick checks, use an online duct calculator instead.
McQuay Duct Sizer (now officially distributed by Daikin Applied

How to Use a Duct Sizer for Properly Sizing Flexible Ducts – KSA - Airlution
If you are an HVAC engineer, contractor, or design-build professional who uses a Mac, you’ve likely encountered a frustrating roadblock: The McQuay Duct Sizer (now part of Daikin Applied) does not have a native macOS version.
For over two decades, the McQuay (Daikin) Duct Sizer has been a staple tool in the Windows ecosystem. It is a free, lightweight, and remarkably accurate program for sizing ductwork based on friction loss, velocity, and flow rate. Yet, for the growing legion of HVAC professionals who prefer Apple hardware, running this tool requires ingenuity.
This article explores the history of the McQuay Duct Sizer, why it never came to Mac, how you can run it today, and what native macOS alternatives exist.
If you’re comfortable with the terminal:
brew install python
pip install ductsize # (A community package)
Then run ductsize --cfm 800 --friction 0.08 to get dimensions. No GUI, but extremely fast and scriptable.
If you own a Mac with an Apple Silicon chip (M1 or newer), do not attempt to run the McQuay Duct Sizer using Apple’s built-in Rosetta 2 translation alone. Rosetta translates Intel Mac apps, not Windows .exe files. You must still use Wine or a VM. However, the latest versions of CrossOver and VMware Fusion are now universal binaries that run Windows x86 code on ARM Macs very fast—often faster than on native Windows hardware.
If you have a Windows machine elsewhere (office PC, cloud instance), use Microsoft Remote Desktop (free on Mac App Store) or TeamViewer.
