Refrigerant Charging
Most non-electrical HVAC/R problems are charge related. Many systems in operation are undercharged or overcharged. This can cause decreased efficiency and compressor failure. The higher the efficiency of a system, the more critical it is that it is charged properly. Measure refrigerant pressure and temperature and calculate superheat or subcooling with our refrigerant charging devices from Fieldpiece.
