EU Regulation 2024/573 - the revised F-Gas Regulation - has set a cascading series of refrigerant restrictions that are forcing HVAC and refrigeration contractors across Europe to overhaul tooling inventories, certification programmes, and retrofit strategies. With the first major service bans in force since January 2025 and equipment-level GWP limits tightening through 2032, service firms face a multi-year transition with direct cost implications.
Regulatory Background
Regulation (EU) 2024/573 entered into force on 11 March 2024, replacing the 2014 F-Gas Regulation and introducing the most stringent HFC phase-down schedule the bloc has implemented. The legal framework operates through two parallel mechanisms: a quota system capping total HFC volumes placed on the EU market, and product-specific placing-on-market bans tied to GWP thresholds.
From January 2025, EU HFC production rights are capped at 60% of producers' average annual output from 2011 to 2013, declining to 15% by 2036. Also from January 2025, the use of virgin refrigerants with a GWP of 2,500 or higher is prohibited for servicing any refrigeration system, targeting equipment still operating on R-404A.
The bans cascade across equipment categories. For single-split heat pump systems charged with less than 3 kg of F-gas, the applicable GWP limit from January 2025 is 750 - not 150, as is frequently misreported. Larger heat pump configurations and monobloc systems below 12 kW transition to the GWP 150 limit in January 2027. From January 2030, the available HFC quota falls to just 5% of the 2015 baseline, representing a 95% reduction in virgin high-GWP supply.
Member states had until September 2025 to adapt national training and certification schemes to implement changes required by the new regulation.
Details: Costs, Tooling, and Country-Level Certification
Wholesale pricing data illustrates the divergence already emerging among compliant A2L refrigerants. In mid-2026, R-32 trades at approximately €25-40 per kilogram across EU wholesale markets, while R-454B commands €40-60 per kilogram. The price gap reflects R-454B's more complex manufacturing process - it blends R-32 with R-1234yf - and its lower European production volume.
R-32 accounts for approximately 55% of new split air-conditioning and heat pump installations across Europe in 2025, compared to an estimated 10% share for R-454B, according to Eurovent and EHPA market estimates. According to Daikin, which introduced R-32 systems in Europe from 2014, the refrigerant "remains the balanced refrigerant for many applications in the years to come, allowing for continued heat pump adoption in a cost-effective way."
For contractors, the tooling investment required to handle A2L refrigerants - A2L-rated recovery machines, vacuum pumps, manifold sets, and leak detectors - typically adds €1,500-3,000 to a service firm's equipment budget. The more significant operational cost is technician upskilling. Updating F-gas certification to cover A2L handling procedures takes approximately one to two days per technician.
National certification structures vary. Germany requires a Sachkundenachweis through the IHK under the ChemKlimaschutzV, the Netherlands uses Stichting F-Gassen, and France administers the attestation de capacité. All country-level certifications must now cover A2L refrigerant handling, including training on flammability-rated tools and leak detection procedures.
Retrofit feasibility is constrained by fundamental incompatibilities. R-410A and R-32 operate at different pressures, and a direct refrigerant swap would violate EN 378 safety requirements. In practice, most retrofit scenarios require a full outdoor unit replacement, though some manufacturers offer dedicated R-32 conversion kits as an alternative. EN 378, the harmonised European safety standard for refrigerating systems and heat pumps, was revised in 2024 to expand the framework for A2L refrigerants with updated charge limits and room-size calculations.
Supply chain pressure compounds the cost picture. Global R-32 output currently meets approximately 85% of demand, creating regional shortages during peak installation seasons. R-32's reliance on fluorochemical feedstocks - with China controlling approximately 63% of global fluorspar reserves - has introduced sustained price volatility, with anhydrous HF prices fluctuating by ±25% quarterly since 2022.
Certification coverage among technicians remains uneven. Current A2L certification programmes cover an estimated 35% of HVAC technicians in major markets, creating service capacity limitations.
Outlook
The EU HFC quota is set to move from 31% of the 2015 baseline in the 2024-2026 period to 24% in 2027-2029, before falling to 5% in 2030. That trajectory will progressively force reliance on reclaimed and recycled refrigerant for legacy system servicing - a segment that currently lacks sufficient European reclaim infrastructure to match anticipated demand.
Manufacturers are responding at the product level. According to Daikin, refrigerants such as R-454C - with a GWP of 145.5, below the forthcoming 150 threshold - "can bring affordable, efficient and safe heat pumps to a broader market" ahead of the 2027 ban deadline. Service firms that delay A2L certification updates and tooling investment face compounding compliance risk as each successive regulatory milestone removes additional servicing options for legacy equipment.
