Mixing Duracool 22a with R-22 is not recommended. While Duracool 22a is designed as a drop-in replacement for R-22, combining the two can lead to system inefficiencies, potential damage, and legal issues due to blending different refrigerants. It's best to fully evacuate the system and charge it with only one type of refrigerant for optimal performance and safety. Always consult a professional HVAC technician for guidance.
