Great App, very helpful. 😃
The best free application for HVAC Duct sizing
Best aplication
Overall I like the app. What I don't like, every time I start the app I have to click on "duct size velocity" ant to set 500 fpm. The app can't "remember" this preferences, goes to the default mode. Maybe a great addition could be adding internal liner (1/2" and 1"). The ductulator can show both outside and inside duct dimensions. Also, the tabs for altitude and pressure drop are so wide! Was useful to have them narrow like others, eventually airflow, velocity and duct sizes could be wider for easy access.
Lovely just what i needed thank you very much this is the first 5 stars ip ever gave in my whole 23 year old life.
Not too much flexibility in terms of varying inputz and changing units. Also interface is not intuitive and hard to use.
The app is easy to use and has several options for computing friction loss. It should be noted that the velocity presented is the velocity in a duct of equivalent diameter, not the velocity in the actual rectangular duct - but that seems to be the common approach based on ASHRAE standards.
It has lots of different unit selection options and 2 different user interface which is very useful.
Very useful for fast estimation and calculation. Very flexible at different units.
Very useful and simple and of course free
nice and useful !!
It's a time saver!
Cannot solve for cfm based on other criteria except trial and error. Does not have an option for the industry standard nomagraph wheel. Does not allow moving app install to SD card. Pretty disappointing, probably will have to pay for a better one.
Very useful and free.
Thank so much
I like it. Useful to check the duct size with relate parameters.
