Get the guidance, support, information, and tools you need—on the job and in the field. Ref Tools is a free, powerful app that contains essential tools every HVACR technician needs in their digital toolbelt. 
 
Ref Tools offers a collection of useful air conditioning and refrigeration tools:

Magnetic Tool

Troubleshooter

Product Finder 
Find extensive product-related data in one place. Search by product code number or product category to access and share product specifications, documentation, visuals, and more. 

Spare Parts

Podcasts 
The workday can be full and the road long, so Ref Tools also provides you with some educational entertainment. You can listen to podcasts, including the popular Chilling with Jens podcast, directly in the app. So, take a break and chill out a bit while learning something new about refrigeration. 
 
More about Refrigerant Slider 
Refrigerant Slider, now a part of Ref Tools, helps you quickly calculate the pressure-to-temperature ratio for more than 80 refrigerants, including natural refrigerants such as ammonia and transcritical CO2.  

Refrigerant Slider also provides you with information about each refrigerant, including Global Warming Potential (GWP) and Ozone Depleting Potential (ODP). You can switch between the IPCC AR4 and AR5 values, where AR4 values are used in relation to the European F-Gas regulations. 
 
Refrigerant Slider’s P/T calculations use extended curve–fitting models based on Refprop 10 results. You can also see both dew and bubble point for refrigerants with glide. 

Streamline your workflow 
Ref Tools goes beyond just providing quick access to helpful tools; it helps you save time by allowing you to track your most visited service sites and save unique settings for each one. Simplify each service call with ease.
