McQuay (now part of Daikin Applied) made a useful Duct Sizer utility that HVAC designers and contractors rely on to size ductwork quickly. If you’re a Mac user hunting for an accessible, Mac-friendly way to size HVAC ducts using McQuay’s tools or equivalents, here’s an engaging, practical piece you can use on a blog, product page, or newsletter.
If you already use Autodesk products on Mac (AutoCAD for Mac or Revit for Mac), many add-ins include duct sizing tools. For example:
| App Name | System Requirements | Key Features | Price Model | Notes | | :--- | :--- | :--- | :--- | :--- | | | macOS 15.6+, Apple M1+ chip | Instant duct sizing; range of suitable sizes; uses friction rate or velocity; modern interface | App Store Purchase / Subscription | A modern, fast, and well-reviewed app designed for the latest Apple Silicon Macs. | | DuctSizer | macOS 11.0+, Apple M1+ chip | Quick finger-slide calculation; shows equivalent round and rectangular sizes; supports IP & SI units | ¥38.00 (approx. $6 USD) | A simple, dedicated ductulator app that is functional and affordable. | | ASHRAE HVAC Duct Sizer | iOS/macOS (via App Store) | Digital version of the classic Trane Ductulator; uses constant friction method; sizes single runs or ranges | Typically paid | Developed with ASHRAE standards in mind, offering professional credibility. | | Duct Calc Elite | Mac (via emulator like BlueStacks) | Provides quick duct sizing and airflow answers; shows round/rectangular options with aspect ratios | Freemium | An Android app that can be run on Mac using an Android emulator like BlueStacks. | mcquay duct sizer for mac
However, the application was built exclusively for the Windows OS architecture. It cannot execute directly on macOS without intermediary translation software. Method 1: Running the Original McQuay Duct Sizer on Mac
If you want to skip the headache of running Windows apps on a Mac altogether, several excellent native macOS alternatives deliver the exact same mathematical results. 1. Mac-Specific HVAC Apps McQuay (now part of Daikin Applied) made a
It is a user-friendly program that incorporates a library of duct materials, fitting types, and equipment selection options, making it a comprehensive tool for HVAC system design. The software generates a detailed duct layout, including sizing, pressure losses, and fan power requirements.
The original McQuay Duct Sizer is a legacy Windows-based executable (.exe). Because it was never ported to Mac, users generally follow one of three paths: 1. Native Mac App (Best for Apple Silicon) For example: | App Name | System Requirements
Trane offers a digital version of its famous Ductulator, which offers identical functionality to the McQuay tool. It is often available via the App Store. 3. ASHRAE Duct Fitting Database
