Where’s the option for flex duct?

Not happy with my purchase

GREAT APPLICATION

I've been using it for many years, my go to every day.

Really mot good app .

Calculation are not acure , not integral proximity in calculations

Subscription

Do I have to pay monthly subscription for this app or just one time pay at the start?

Almost perfect… but not quite there.

This thing is great. only 2 things would make it perfect. 1) Flex duct sizing. 2) multiple friction rate fields, so you can select both your return AND supply friction rates at the same time and see output of both. plus have those fields be lockable so you can’t change them by accident. If these changes were made, I would buy this AGAIN and likely so would every consultant in my company.

The app is designed for HVAC engineers, designers, and contractors to quickly and accurately size new ductwork or calculate the performance of existing ducts. It allows for precise calculations of duct dimensions, airflow, velocity, and pressure drop.

How can I use the Duct Calculator app?

You can use the app by adjusting airflow and duct dimensions (diameter, width, height) using intuitive sliders for quick calculations, or by entering exact numbers directly for maximum precision. Specific dimensions can be locked to perform 'what-if' analyses.

Is the Duct Calculator app free to use?

Yes, based on the provided information, the app is available for free. There are no mentions of in-app purchases or subscription models.

What types of ductwork can be sized with this app?

The app supports sizing for both round and rectangular ductwork. It provides equivalent round and rectangular duct sizes, as well as outputs for velocity and pressure drop for both types.

What units of measurement does the app support?

The app is designed to work with both Imperial (IP) and International System of Units (SI). This allows users to perform calculations according to their preferred measurement standards.
