ef-22a is a hydrocarbon refrigerant that replaces R22
R22 - Can be easily replaced with the hydrocarbon version EF-22a. Made by ecofreeez.
Absolutely. No need to change any oils or fitting. Top off or replace. works great. Just remember you need a lot less of it in the system.
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.
R-22 and R-22A cannot be mixed because they have different chemical compositions, pressures, and properties, which can lead to system inefficiency and potential damage. R-22 is a hydrochlorofluorocarbon (HCFC), while R-22A is often a hydrocarbon blend, which can create compatibility issues with the compressor and other system components. Mixing the two can also affect the refrigerant's performance and increase the risk of leaks or safety hazards. Therefore, it's crucial to use only one type of refrigerant in a system at a time.
To replace R-22 with R-22A, first ensure that your system is compatible with R-22A, as it is a blend and may require adjustments. Recover the existing R-22 refrigerant according to local regulations, then check for leaks and repair any issues. Once the system is leak-free, vacuum the system to remove moisture, and then charge the system with R-22A according to the manufacturer’s specifications, monitoring the pressures to ensure proper operation. Always consult with a certified HVAC technician for best practices and compliance with regulations.
No
If a technician discovers that R502 was added to an R22 system, he should first isolate the system to prevent further contamination. Next, he should recover the mixed refrigerant using a certified recovery machine and dispose of it according to environmental regulations. After that, the technician should thoroughly evacuate and vacuum the system before recharging it with the appropriate R22 refrigerant. Finally, he should conduct a pressure and leak test to ensure the system is functioning correctly and safely.
NO ! and Why?
R-22A is a refrigerant that is sometimes considered as a drop-in replacement for R-22, but it is not a direct substitute. While R-22A can be used in some systems, it requires careful evaluation of compatibility with the existing components and oil types in the system. Additionally, R-22 is being phased out due to environmental regulations, so transitioning to R-22A may provide a temporary solution, but ultimately, systems should be converted to more environmentally friendly refrigerants that comply with current regulations. Always consult with a certified HVAC technician before making any changes to refrigerants.

No, R22 is for refrigerators and home AC. It runs at a different pressure and you can't use one for the other.
