Simple, fast and everything you need if you don't have a duculator with you. Seen the bad reviews, if you have enough experience everything you need is in the app
Love this app since im in the HVAC business
Not worth a dollar. Its literally just plain and bare calculation. You punch in CFM and in/100ft and it tells you one size round duct and 2 box duct sizes. Where's the calculation for how many rooms the house has? Where's the explanation and/or education behind CFM's nd what not? The only reason I gave it an extra star is because its a fast calculator.
I was hoping to find a way to find alternative duct sizes, but the only option I get is to choose a CFM, out on the field you don't have that luxury.
Complete pile of junk
This is great for new construction hvac systems
A really simple and productive app. Great for making fast duct design decisions
Wrong calculations bad app I make several tries to check it was wrong.
feels like its missing more options or selections.
Good
