Your Job Has Challenges.

As a service technician, your job is a big part of who you are now and who you want to become. Each day brings with it new challenges to understand unique situations, diagnose problems and recommend fair and reasonable solutions: 


  • How will you make the homeowner feel comfortable with your solutions?

  • How will you make your manager feel confident in your work?

  • How can you move on to the next job as quickly as possible?

You Have Access. 

Ask any senior technician and they will tell you, twenty-five years ago, timely access to on-the-job information was nearly impossible to get.  With mobile devices in almost every hand and access to a plethora of Apps, videos and blogs - times have changed.

We Have a Solution.


Are there HVACR Apps out there that can empower you to work smarter and more efficiently?  Sure. 


Are there HVACR Apps out there that can guide you through job scenarios, troubleshoot, diagnose, and teach - without a subscription? 


There is now.  

An on-the-job companion connected to your world.


What it Does

The Supco TechLink™ App is designed to be used with Supco's® line of connected test instruments.

No need to use separate Apps for each test instrument.

All compatible products are kept in a Toolbox on a single FREE App.  


Click to view the current list of Supco® TechLink™ compatible products.


Connect one or more connected test instruments and save it to the App's toolbox for remote monitoring.  The toolbox will display basic readings from the connected instrument.


Guided tests and diagnostics take the user step-by-step to properly test components, electrical circuits and systems.  Help screens aid with steps and even provide product recommendations.


Real-time viewing of target, min max and average measurements on a combination analog/digital interface.  Measurements are logged and available to view on a trending line graph for analysis.


Results from guided tests and recordings can be exported out of the App as a text-based CSV file or as a formatted PDF for easy sharing with other service techs, your company and 
your clients.


A record button allows you to log data and measurements until you stop it.  Once stopped, the log will save measurements for further analysis.


Educational content and tips on testing, diagnostics, components and blog updates will be available in the news feed.
