Refrigerant regulation is reshaping the parking AC industry. R410A — the current industry standard with GWP of 2088 — faces phase-down in the EU (F-Gas Regulation 2024 revision) and progressive restriction in the USA (EPA AIM Act). R32 (GWP 675, 68% lower than R410A) is the leading transition refrigerant for new equipment. This guide explains the technical and regulatory implications for truck and RV parking AC buyers in 2026.

R32 vs R410A technical comparison

GWP: R32 = 675 vs R410A = 2088 (R32 is 68% lower). Cooling capacity per kg refrigerant: R32 ~15% higher. Operating pressure: R32 slightly higher (compressor designed accordingly). Flammability: R32 is A2L (mildly flammable) vs R410A A1 (non-flammable) — requires updated handling protocols but is widely adopted in mainstream residential AC. Charge size for given capacity: R32 requires ~30% less refrigerant by mass.

Regulatory transition timeline

EU: F-Gas 2024 revision phases down high-GWP refrigerants progressively to 2030. R410A new equipment restricted in many EU member states from 2025. UK aligned with EU schedule. USA: EPA AIM Act phase-down of HFCs began 2022 with 85% reduction by 2036; R32 currently approved for new equipment. China, Japan, India, Australia: R32 adoption growing rapidly. Vethy provides R32 variants for export markets requiring lower-GWP refrigerant.

Practical impact on parking AC buyers

For 2026 buyers in the EU, UK and some US states: specify R32 for new fleet purchases to avoid future regulatory exposure. For Mexico, GCC, Australia and most other markets: R410A remains fully compliant and is the cost-effective standard. Vethy offers both refrigerant options across the lineup; specify on order.

Service and aftermarket considerations

R32 service requires F-Gas / EPA 608 certified techs trained for A2L refrigerant handling — increasingly standard across the industry but verify your local service network before specifying R32. R410A service is universally available. Both refrigerants offer 10–15 year sealed-system life with no top-up needed under normal operation. All VS02 PRO / ZH 1000 / VC 1000 / VC 2000 models support both refrigerant options at factory.

Frequently asked questions

Is R32 banned in the EU?

No. R32 is approved for new equipment in the EU. R410A faces progressive phase-down due to higher GWP — R32 is the approved transition refrigerant.

Will R410A systems be illegal to service in a few years?

Servicing existing R410A equipment remains legal in all major markets — phase-down restricts new equipment manufacture, not service of installed base. Plan for decade-plus service availability.

Is R32 dangerous due to flammability?

R32 is A2L (mildly flammable, requires ignition source). Handled properly by certified techs it is safe — used in millions of residential AC units worldwide. Charge size in parking AC is small (<1 kg) limiting risk.

Does R32 deliver better cooling per amp?

Modestly yes — approximately 5–8% higher EER (Energy Efficiency Ratio) than equivalent R410A. Useful but not transformative for battery-powered parking AC applications.
