Johnstone Supply Toolkit
1. Duct Sizer: This module allows you to quickly size one HVAC duct run or a range of duct sizes for a wide variety of duct materials and shapes.
2. PT Chart: This module is an electronic pressure-temperature (PT) look-up chart that allows you to specify the exact refrigerant temperature/pressure and view the corresponding pressure/temperature value. It also displays a complete list of pressure/temperature values in 1 degree increments for over 70 different refrigerants. You can adjust the elevation so proper gauge pressures are displayed. Additional functionality includes the ability to display specific refrigerant properties and email the entire PT chart list for a specific refrigerant.
3. Capillary Tube Calculator: This module allows you to perform capillary tube look-up based upon HP, condenser cooled type, and refrigerant type.
4. Store Locator: This module allows you to find the closest Johnstone Supply store to where you are currently located. You can also type in a zip code to find all Johnstone Supply stores within a specific radius.
5.AC/Gas Furnace Efficiency Savings Calculator: This module allows you to quickly calculate the energy savings for cooling or heating based upon selecting the old/new unit information and your region.

Crashes immediately on launch
I didn't have to read much before I realized it was a great app. It also helps find the supply houses. Very helpful
Downloaded this app 4 times now & can't get ductulator to work. The message is: JS tools has stopped responding.
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....
For what it is and what it cost its the best. 1 download 3 apps very customizable options. Trusted source.
Needs the an option for choosing the units of measurement. Only the US uses Fahrenheit, the rest of the world uses Celsius. kW, TR and BTU/hr would also be useful instead of just HP.
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.
You have to work on it.
Very convenient with this because it has all refrigerant. Thank you so much. I love it
Tried the paid apps and though somewhat usefull this one is far better!
I would like capillary tube selection chart
Simple and useful.
Easy and convenient
It's ok
This is great, I'm a mechanical engineer and I now have a ductalator worth me in every meeting I go to
Some of the most prevalent R22 replacement refrigerants R421A, R422B, and R438A, are not listed in your temperatures and pressures chart
Does what it says
Crashes on launch...what is wrong with it?
