#r410a

Five refrigerants are competing to replace R-410A under the HFC phasedown, and a 2025 Springer study finally ran them all through the same head-to-head analysis: R-32, R-290 (propane), R-454B, R-454C, and R-513A, scored on energy, exergy, and total environmental impact.

The efficiency winner: propane. R-290 hit a COP of 7.91 at the study's optimal operating point against 7.49 for R-410A, a 5.6% edge, plus the best exergy efficiency of the group at 0.52. R-454C brought up the rear at 5.80.

But the emissions scoreboard flipped the podium. On Total Equivalent Warming Impact, which counts refrigerant leakage AND the emissions from the electricity a system burns, R-454B came out cleanest at 13.3 metric tons CO2e, about 16% below R-410A. R-290 landed at 14.8.

The twist: R-454C finished dead last at 18.4 tons despite carrying the lowest GWP of any blend in the test. Poor efficiency means more power-plant emissions year after year, and that swamps the low number printed on the cylinder. TEWI counts the meter.

The practical read: the OEMs bet well. Carrier and Trane went R-454B, which takes the emissions crown. Daikin and Goodman went R-32, which ran about even with R-410A while cutting GWP by roughly two thirds. And propane's efficiency win keeps its A3 asterisk; charge limits keep it out of US ducted splits, so you'll meet it in window units and European monoblocs instead. R-513A, the lone A1 nonflammable in the lineup, ran mid-pack on every measure, which is about the trade you'd expect for skipping flammability entirely.

None of this changes which cylinder lands on a service truck. The manufacturers decide that. It does change how you explain the transition to a customer staring at a changeout quote, because two of the five candidates beat the outgoing refrigerant on the metrics that matter.

The study: Ashour et al., International Journal of Air-Conditioning and Refrigeration, 2025.

EPA's May 26 final rule rewrote the HFC phasedown calendar, and if you service AC or refrigeration equipment, the details matter.

The headline change: the installation deadline for residential R-410A systems is gone entirely. Equipment with a GWP of 700 or higher that was manufactured or imported before January 1, 2025 can now be installed with no cutoff. The old deadline was January 1, 2026.

The rest of the calendar slid too. Supermarket refrigeration moved from 2028 to 2032 with an interim GWP cap of 1,400. Cold storage warehouses went from 2026 to 2032 with an interim limit of 700. Lab equipment gets until 2028, semiconductor process refrigeration until 2030.

EPA's own estimate says the delays add 68.1 million metric tons of CO2-equivalent emissions through 2050, against a claimed $2.4 billion in savings over 24 years. Critics say aging high-GWP systems leak more and burn more energy, so the savings could evaporate into higher food costs.

For techs, two things are true at once. The A2L transition is not canceled, manufacturing deadlines didn't move, so new residential equipment is still R-454B and R-32 and the training still matters. But the R-410A service tail just got years longer, which firms up the reclaim market since virgin production allowances are still stepping down on schedule.

And remember: states like California run their own refrigerant rules through CARB and aren't bound by the federal delay. A shop working across state lines could be running two different compliance calendars for identical equipment, so check your state's rules before assuming the new federal dates apply to you.

The practical takeaway for this season: recovery equipment and 410A cylinder inventory just became longer-lived investments than they looked a year ago. Shops that treat recovery as a profit center rather than a chore are the ones positioned to win as the reclaim market tightens through the early 2030s.

California is about to start paying contractors for recovered refrigerant.

CARB selected Hudson Technologies on December 9, 2025 as one of two approved reclaimers for REFRESH, a new refrigerant-recovery incentive program. Funding draws from the state's F-gas Reduction Incentive Program, up to $5 million. Program administration goes through NASRC.

Two refrigerants qualify: R-410A (the one in most residential systems from 2006 onward) and R-22 (the older one still in service on systems 15+ years old). Contractors get a bonus on top of the standard reclaim payment when they recover these gases instead of letting them escape.

The timing is tied to California's 2030 ban on new R-410A sales. The state wants the installed base to get recovered cleanly, not vented. REFRESH is the carrot.

If your recovery documentation is sloppy, tighten it up. Enrollment is expected to open in Q2.
