FAQ:
Q: Is the R-410A a liquid or blended refrigerant?
A: Also, Since R-410A is a blended refrigerant it is best to evacuate the refrigerant as a liquid. This ensures optimum and consistent performance. This is recommended by Chemours and other leading manufacturers.
Q: What’s the difference between R-22 and R-410A?
A: Unlike R-22 the new R-410A is a blended refrigerant mixed up of R-32 and R-125. In some instances blended refrigerants act differently then single refrigerants. We will get into that further on down this list.
Q: Are there any flaring tools for the R-410A?
A: While your existing flaring tool may work there is a chance of leaks when working with R-410A due to the pressure. There are flaring tools specifically designed for R-410A that will allow for ease of use and minimize chance of leaks.
Q: What kind of lubricant to use on R-410A compressor?
A: R-22 tools will NOT work on 410A! Instead of the mineral oil lubricant you would use for R-22 you will be using a synthetic oil called Polyol Ester Oil, or POE. This oil is actually more soluble with R-410A which causes your compressor and your system to operate more efficiently.
