R-134a and R-404A checks for Hempstead APU calls
Freon recharge pages focus on refrigerant recovery, deep vacuum, leak checking, and weighed charging instead of pressure-only top-offs.
Vacuum pull and micron gauge
A proper vacuum pull helps remove air and moisture. Micron readings are watched to see whether the system holds before refrigerant goes in.
Charge by measured weight
R-134a, R-404A, or a custom label is verified before charging. The target is based on the equipment, not a blind pressure number.
Temperature split proof
After charging, vent temperature, suction behavior, discharge behavior, and condenser airflow are checked under Hempstead roadside conditions.
