: Compatible with macOS 11.0 or later on Apple Silicon Macs. 2. Run the Windows Version via Virtualization The original McQuay Duct Sizer (now under the Daikin Applied brand) is a lightweight Windows executable ( ). You can run it on any Mac using:
allows you to run Windows applications directly on macOS without a full Windows license, though it can require more technical configuration.
The transition of the McQuay brand to Daikin Applied Tools did not bring a native macOS desktop overhaul. Fortunately, engineering workflows on Apple hardware can easily bridge this gap.
The McQuay Duct Sizer is a specialized software tool designed for HVAC professionals to assist in the accurate and efficient sizing of air ducts. It is a free, compact software tool used to size air ducts using multiple methods. As a key subsidiary of Daikin Industries, McQuay International holds a prominent position in the HVAC/R industry, and their software reflects a commitment to innovation and industry leadership.
Native app, intuitive slider controls, supports I-P and SI units, directly calculates rectangular and round ducts. Cost: Paid app, but very affordable for professionals. 2. Trane Ductulator App (Mobile/Desktop)
Download a utility like Wineskin Winery or CrossOver (a polished, paid version of Wine). Create a "wrapper" or "bottle," select the McQuay .exe installer, and run it.
Accurate duct sizing is the backbone of any efficient heating, ventilation, and air conditioning (HVAC) system. For decades, the McQuay Duct Sizer—now maintained under the Daikin Applied brand—has been the gold standard software for mechanical engineers, estimators, and HVAC technicians. It simplifies complex fluid dynamics equations into a straightforward, digital version of the classic friction chart wheel.
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
Requires a paid subscription for Parallels and a Windows license. 3. UTM Virtual Machines (Free Alternative to Parallels)
Input your design airflow (CFM) and one other variable, such as a velocity limit.
It specializes in sizing ducts based on a set friction loss (typically 0.1 inches of water gauge per 100 feet).
The traditional McQuay DuctSizer (often downloaded as DuctSizer.exe ) is a legacy Windows application.
Regardless of whether you run the utility via virtualization or an app alternative, the sizing physics remain identical. The engine uses the or the Equal Velocity Method to balance fluid dynamics with acoustic limits. Design Software Tools - Daikin Applied
