Mixing R-22 and R-422B (commonly referred to as Nu-22) is not recommended, as it can lead to system inefficiencies, increased pressure, and potential damage to the HVAC system. R-422B is a replacement for R-22, but they have different properties and pressure characteristics. If you need to switch refrigerants, it's best to completely evacuate the system of the old refrigerant and charge it with the new one. Always consult with a qualified HVAC technician for proper handling and replacement procedures.

Can you mix NU22 with R22?

Mixing NU22 (a refrigerant blend) with R22 is not recommended, as it can lead to system inefficiencies and potential damage. NU22 is designed as a replacement for R22 but has different properties, which can affect lubrication and pressure characteristics. Additionally, blending refrigerants can complicate recovery and recycling processes, making it difficult to comply with environmental regulations. It's best to fully evacuate the system and use the appropriate refrigerant specified for your application.

Can you top off r22 with r22a?

No the whole system need to be evacuated of the r22 before you put r22a in the system. It's against the law to mix 2 different freons together and also dangerous.
