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. 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.
