What happens if you mix R421a with R22?
the simple answer is no. If a technician were to “top-off” an R-22 system with R-421A, they would essentially be creating a refrigerant mix that is not authorized by the EPA. It is a Federal violation to knowingly mix refrigerants. R-421A will not operate correctly if mixed with other refrigerants.
Is R410A phased out?
R-410A is scheduled for elimination from all new systems in 2023.
Does R421a replace R22?
R-421A is a drop-in replacement for R22 systems. With this refrigerant there is no need to change the oil. Simply recover the R22 and recharge with R421A.
Is R421a a good refrigerant?
This last important fact makes R421a from Choice Refrigerant the safest product for any system that works with R22. Refrigerant Guys labs tested R421a on mid temp systems and found no particular problems.
What can I replace R407C with?
The replacements or alternative refrigerants for R407C include R32 and R444B as well as other various mixtures of HFO refrigerants.
Which is better 407C or 410A?
While R-410A’s operating pressure at high ambient temperatures is inarguably higher than that of R-407C, at Super Radiator Coils, we’re able to produce UL-listed solutions that use R-410A for up to 700 PSIG, making it a completely safe and effective refrigerant for warmer climates.
What is replacing R-410A?
The leading replacement for R-410A refrigerant is a pure, single component refrigerant called R-32, which has one-third the global warming potential of R‑410A. Some products with this next generation refrigerant have already been introduced in the United States.

Is R407C banned in UK?
As there is no usage ban for this group of refrigerants, installations running on R134a, R407C, R407F and R410A may still be refilled after 2030.
Is R22 still available?
R22 is no longer produced or imported into the United States, but it still exists inside some older HVAC units. If your unit uses R22 and runs out, HVAC technicians may still have access to the existing recycled or recovered R22 supply and can service your unit as normal.
Do they make a 407C heat pump?
The choice of the refrigerant impacts the performance and behavior of any heat pump system. The most interesting refrigerants for heat pump applications presently are R410A and R407C.
What is the new refrigerant coming out in 2023?
R-454b
It might surprise you to learn that Carrier announced that starting in 2023, all of their residential HVAC systems in North America will move to a new refrigerant Puron Advance™ (R-454b). This refrigerant blend has fraction of the Global Warming Potential (GWP) that R-22 or Freon® did.
What is the next refrigerant?
R-32 is a next generation refrigerant that efficiently carries heat and has lower environmental impact. Refrigerant is a medium for conveying heat. Air conditioners transfer heat while circulating refrigerant between the indoor and outdoor units.
Is r421a safe to use with R22?
This last important fact makes R421a from Choice Refrigerant the safest product for any system that works with R22. 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).
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).
Does a retrofit to r421a improve performance?
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 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).
