Refrigerant-Side Performance
Before you hook up a refrigerant gauge to a condensing unit or heat pump, 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!
Who should attend?
Residential technicians, installers & installation managers, service managers

This three-day course builds on principles learned in other NCI courses and applies them to the residential system design or redesign processes. NCI uses industry-approved standards for load calculations, equipment selection, duct design and grille and register selection.
There Is A Better Way!
What if everything you thought you knew about diagnosing and solving refrigeration-side performance problems may not be totally correct?
This National Comfort Institute two-day advanced residential 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:
- 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
- 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
