Ever had an HVAC system low on refrigerant which some folks call freon? In this video, Joshua Griffin shares why you can't just easily connect gauges to a ductless mini-split system as you would connect to a typical air conditioner or heat pump. This goes for inverter HVAC systems as well. Connecting gauges to a system of these types that have to ability to ramp up and down does not allow you to do full-capacity superheat and subcool measurements. Therefore, you won't be able to tell if the system is properly charged without properly weighing the refrigerant in.
