The Johnstone Supply Toolkit is a free HVAC mobile application that includes the following functionality:
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.
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.
