HVAC technicians cannot use traditional gauges to check refrigerant charge on Mitsubishi systems and must instead weigh the refrigerant, which is time-consuming and less precise.

Traditional HVAC diagnostic tools (gauges) are incompatible with modern modulating systems like Mitsubishi, forcing technicians to use a manual, less efficient weighing method.
