Normal Subcool High Superheat. Low Superheat High Subcooling 7 Reasons and Troubleshooting After that, you should see the high superheat come down to normal superheat and high subcooling come down to normal subcooling This is the easiest high superheat cause you can fix because you only have to bring the indoor temperature down a bit

The fact that these readings are normal indicates the low suction pressure is not caused by low refrigerant, but insufficient heat getting to the evaporator Example: Low refrigerant charge causes high superheat, but it does not cause high superheat normal subcooling
Learn about the implications of normal subcooling with low superheat and discover the potential causes and solutions for this unique situation. Learn about the implications of normal subcooling with low superheat and discover the potential causes and solutions for this unique situation. If you have a piston as a metering device, there are also two options for why such a piston might be underfeeding the refrigerant: Piston is not correctly sized.
Can you explain me more about expansion valves? What if subcooling is. If you have a piston as a metering device, there are also two options for why such a piston might be underfeeding the refrigerant: Piston is not correctly sized. So a condition where you have excess refrigerant in the coil and enough refrigerant in the condenser is referred to as high superheat normal subcooling .
HVAC Superheat and Subcooling Explained! Understand the Concepts Step. CAUSE #2: Defective, plugged, or undersized metering device. That's because low charge results in high superheat AND low subcooling (we have covered this in high superheat low subcooling issues here)
