I miss my old one I miss my original paper ductulator from Johnstone!!!!! This app needs work. example, The conversion on duct. If I have 20"round duct,and need to convert it to square/rectangular. The original paper ductulator would give me several "dimensions"of square duct that I could use for change orders or RfI....
Needs improvement Nice start but needs some more work. It is not better than the paid version for the ductulator like some of the comments state. The seer savings calculator is also not working properly and doesn't offer the option to select tonnage.
Downloaded this app 4 times now & can't get ductulator to work. The message is: JS tools has stopped responding.
Free and best Tried the paid apps and though somewhat usefull this one is far better!
A good app I didn't have to read much before I realized it was a great app. It also helps find the supply houses. Very helpful
Best free app for hvac For what it is and what it cost its the best. 1 download 3 apps very customizable options. Trusted source.
