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).Superheat Method. NOTE: Indoor airflow should be within +/- 20 % of rated cfm. 1. Purge gauge lines. Connect service gauge manifold to base-valve service ports.

The line set charge for an HVAC system depends on factors like line set size, length, and refrigerant type. Typically, a 3/8-inch line set may require around 0.2 to 0.8 ounces of refrigerant per foot. The maximum allowable line set length often ranges from 150 to 200 feet. Let’s use the target superheat formula and calculate this manually: Target Superheat (R-410A) = (3 × 69°F – 80°F – 105°F) / 2 = 11.0°F. We see that the target superheat for R-410A refrigerant in this system is 11°F.
