Why choose r421a for R22?
Less components mean less fragmentation at high temperatures and the patented lubricant additive guarantee oil return to the compressor without the use of any Hydrocarbons. This last important fact makes R421a from Choice Refrigerant the safest product for any system that works with R22.
Is r421a a good refrigerant for mid temp systems?
Refrigerant Guys labs tested R421a on mid temp systems and found no particular problems. Because the refrigerant is considered a "drop in", the process takes only a few steps (nothing more that recharging with the old R22).
How to replace the filter drier on my r421a?
The manufacturer recommends to replace the filter drier, pull the vacuum (500 microns or less) and then recharge the unit using the chart of R22. After the retrofit to R421a we monitor the system and we found no significant difference in pressure, compressor temperature and efficiency (air temp at the vent and Amps drained).
How many refrigerant components are in an R-22 alternative?
Many R-22 alternatives on the market have 3, 4 and even 5 separate refrigerant components that comprise the blend. Each of these components have a unique PT curves that can vary from one another widely.
What is R421a made of?

What is the best drop-in replacement for R22?
The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22.
Can you replace R22 with 407C?
R407C can be used to COMPLETELY replace R-22 refrigerant in new or existing R-22 residential and commercial air conditioning systems as well as non-flooded evaporator chillers. Cannot be added to R-22 unless fully evacuated and recharged with 407C.
Can you mix RS44B with R22?
for R22, & Compatible with Lubricants RS44B is compatible both with the traditional mineral & alkylbenzene oils, and also the polyol ester lubricants so that there is no need to change the existing lubricant in the system when retrofitting to R22.
Can you add R407C to R22?
Mixing R22 with R407C or any other refrigerant. According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined.
