EU F-Gas rules and the shift away from R134a: what vehicle AC importers should plan for

The regulation that changes your 2027 product lineup

If you import self-contained air conditioning equipment into the European Union, a date marked on your calendar matters more than any marketing plan: January 1, 2027. Starting that day, Regulation (EU) 2024/573, which replaces the old F-Gas Regulation 517/2014, prohibits placing on the EU market plug-in, monobloc and other self-contained air conditioning units up to 12 kW that contain fluorinated refrigerants with a global warming potential (GWP) of 150 or higher. A limited exception up to GWP 750 applies where safety requirements at the place of operation rule out lower-GWP alternatives, and from 2032 the restrictions tighten further.

This matters more for this product category than most importers realize. A 24V parking cooler or rooftop DC air conditioner is a self-contained unit under 12 kW. Regardless of the original scope of the regulation, it directly hits the truck and RV climate control industry.

Why R134a is the problem

R134a has been the standard refrigerant for vehicle air conditioning for decades, with a GWP of 1430. Under the 2027 regulation, new self-contained units charged with R134a cannot be placed on the EU market after December 31, 2026. The regulation also confirms an earlier established direction: the EU's MAC Directive already required a GWP below 150 for new vehicle types from 2011 and for all new vehicles from 2017, and the US has imposed a comparable GWP limit on refrigerants in mobile air conditioning starting from model year 2020. High-GWP refrigerants have been under increasing pressure for some time; 2027 is when the restrictions also close in on self-contained equipment.

One nuance that saves importers from trouble: the ban applies to placing on the market, not to use. Units lawfully placed on the EU market in 2026 can still be sold and put into service afterward. That's why your ordering schedule for 2026 is just as important as your product lineup for 2027.

R290 and engineering consequences

The leading replacement candidate is R290, propane, with a near-zero GWP. It is already reshaping the development of portable and room air conditioners and will enter vehicle applications through the same physical principles. The catch is the safety class: R290 is an A3 refrigerant, meaning it is highly flammable. The design adaptation is not just a matter of replacing the refrigerant. The entire product architecture must take into account the refrigerant charge, potential leakage scenarios, ignition sources, enclosure ventilation, and the placement of electrical components, and the conformity assessment must cover the specific model and refrigerant charge, not a similar configuration.

What does that mean for a distributor or importer of parking coolers? In practice, three things.

• Your 2027 product range must either switch to a low-GWP refrigerant or provide a documented safety assessment for staying above a GWP of 150. "The supplier says it's okay" is not a safety assessment.
• Service networks need to be trained before the first unit with flammable refrigerants arrives, not after the first repair goes wrong.
• Model-specific documentation, including refrigerant declarations and test reports, becomes part of what you need to keep on file for market surveillance.

A transition checklist for your next purchase order

We go through this list with every wholesale partner who places orders that will still be sold in 2027:

• Ask per model, not per brand. Refrigerant roadmaps vary by SKU. Obtain the declared refrigerant and GWP in writing for each model you stock.
• Match inventory turnover to the deadline. Units charged with R134a ordered in 2026 can be sold, but anything arriving in your warehouse in 2027 must comply. Plan the transition so that neither compliance nor cash flow suffers.
• Review the design evidence for R290 models. Refrigerant charge, A3 safety measures, and the standards used for testing should be included in the technical documentation your supplier provides.
• Check EPREL and labeling requirements where they apply to your category, so that refrigerant compliance is not the only issue.

Where our product range stands

Our DC inverter parking coolers, such as the compact 24V portable cooler, the 12V split parking cooler, and the high-capacity 24V DC truck air conditioner, are built around variable-frequency DC compressors, making them the ideal platform for low-GWP refrigerants. For importers planning volumes for 2026 and 2027, we provide refrigerant declarations and roadmaps per model during the quotation process, before any commitment is made. The same applies to our integrated parking air conditioner range.

Regulatory-driven transitions favor importers who start early. If you would like to review your current product lineup against the 2027 deadline, please contact our technical team through the contact page.
