Refrigerant-Side Performance
Register for this training now! 
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 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
Who should attend?
Residential and Commercial Technicians, Installers & Installation Managers, Service Managers
