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
