What if everything you thought you knew about diagnosing and solving refrigeration-side performance problems may not be totally correct?

Before you hook up a refrigerant gauge to a condensing unit, do you know for certain it’s the right first step to solving the issue?

By tapping into the refrigerant-side and adjusting the charge before you establish the true causes of the problem, you may not solve it. In many cases, you might make things worse!

There is a better way!

This National Comfort Institute two-day advanced residential and commercial certification class provides you with real-world lessons and hands-on training. It’s based on proven techniques on how to best approach refrigeration-side issues.

Learn how to:

  • How to apply a performance-based, systematic approach to refrigeration-side diagnostics
  • Explore new HVAC refrigeration cycle performance-related solutions
  • Identify surgical system repairs to improve performance
  • How to use inspection, testing, and system history to determine if and when you need to tap into the refrigeration circuit
  • Address underlying issues that impact the system before adjusting the charge
