Refrigerant regulations have changed significantly in recent years, and there's a lot of confusion in the market about what it means for existing AC systems. Here's a clear explanation of where things stand.

The Short Version

R-410A, the refrigerant used in most AC systems installed between roughly 2010 and 2024, is being phased down under EPA regulations. New AC equipment manufactured after January 1, 2025 must use lower-GWP refrigerants — primarily R-454B or R-32. R-410A is not banned outright. It can still be used to service existing equipment.

What This Means If You Already Have an R-410A System

If your AC system runs on R-410A today, you don't need to do anything immediately. Your system can continue to be serviced with R-410A refrigerant. The phase-down affects production of new refrigerant, not the use of existing supplies.

However: as R-410A supply tightens, the cost per pound will increase. It was already around $20-30/pound in 2023. By 2026-2027, expect that to climb further as supplies tighten. If your R-410A system develops a refrigerant leak, the economics of repair vs. replacement shift accordingly.

What This Means If You're Buying a New AC System

New systems installed in 2025 and beyond will use R-454B (also called Puron Advance) or R-32. These refrigerants have lower global warming potential. They require slightly different handling procedures but perform similarly in residential HVAC applications.

If you're replacing your system now, you'll receive a new-refrigerant system automatically — this isn't something you need to specifically request. All new equipment is already transitioning to R-454B or R-32.

The Situation for R-22 Systems (Pre-2010)

If your system was installed before 2010 and uses R-22 (labeled "Freon" on older systems), that refrigerant was fully phased out in 2020. R-22 now costs $100-150+ per pound and is only available from reclaimed supplies. If you have an R-22 system with a refrigerant leak, replacement is almost always the economically correct choice. A complete R-22 recharge can cost $1,000+ — applied to a system that's over 15 years old.

The Bottom Line for San Antonio Homeowners

  • R-410A systems can still be serviced — no immediate action required
  • Refrigerant leak repairs on R-410A systems will get more expensive as supplies tighten
  • New systems installed now all use the new lower-GWP refrigerants
  • R-22 systems should be replaced — the refrigerant economics no longer make sense

New Refrigerant Systems and HVAC Services in San Antonio

San Antonio homeowners replacing their air conditioning system in 2025 or later will receive equipment designed for R-454B or R-32 refrigerant. These newer refrigerants require specific recovery equipment and handling procedures that differ from R-410A service. Amazing Air Solutions is fully equipped and certified to service all new-refrigerant systems, including the diagnostic procedures specific to R-454B equipment. If you are having a new system installed, confirm that your contractor is properly equipped to service the refrigerant type in the equipment they are installing — not all HVAC companies have updated their tools and training to match the new refrigerant landscape.

What the Refrigerant Transition Means for San Antonio AC Repair Costs

For R-410A systems already in service, the refrigerant transition primarily affects the cost of repairs involving refrigerant. As R-410A supply tightens through the phase-down period, the cost per pound will continue rising. A San Antonio homeowner with an aging R-410A system that develops a refrigerant leak faces a different repair vs. replace calculation than they would have just a few years ago. A repair requiring 5 pounds of refrigerant at $60 or more per pound significantly changes the math compared to a $20 per pound repair. Amazing Air Solutions provides transparent refrigerant pricing and a clear repair vs. replace assessment for any San Antonio homeowner facing this decision. Call (210) 570-9431 for honest guidance.
