Here are the steps to properly charge a 410a AC system: Turn on the air conditioner. Connect the gauges. Measure the system’s pressures and temperatures. Calculate the target subcooling and superheat. Add refrigerant. Monitor the subcooling and superheat. Disconnect the gauges. Check the system’s performance.heat a cylinder for faster charging, partially immerse it in warm water. • never fill a cylinder more than 80% full of liquid refrigerant. • never add anything other than r-22 to an r-22 cylinder or r-410a to an r-410a cylinder. the service equipment used must be listed or certified for the type of refrigerant used.Good Subcooling Value for R-410A: Similar to superheat, the ideal subcooling value for R-410A can vary depending on factors like system design and operating conditions. However, a common target for R-410A systems is to achieve a subcooling value in the range of 8 to 15 degrees Fahrenheit (°F) or approximately 4.4 to 8.3 degrees Celsius (°C).In this HVAC Training Video, I Show 4 Examples of Checking the R410A Refrigerant Charge Levels on Air Conditioners. We Measure the R-410A Pressures, Saturate...I originally wrote this guideline back in 2003, and truthfully, not much has changed since then in regards to checking a heat mode charge on a heat pump. Step #1 – If there is any frost on the outside unit, get it completely defrosted first. Step #2 – Check all the obvious things first, filter, coils, blower wheel, etc.Input these temperatures in a superheat chart, calculation, app, or digital manifold set in order to determine the Target Superheat at that moment. Remember that the target superheat will change as the building lowers in WB and while charging refrigerant.
