What the AI looks for in Refrigerants

Refrigerant type
Check the underhood label: R-134a or R-1234yf; never mix them The two use different service ports and equipment and are not interchangeable.
Charge by spec
Charge to the weight on the label; use a gauge, not guesswork Overcharging reduces cooling and stresses the compressor.
Oil type
Hybrids and EVs with electric compressors usually need POE oil; avoid PAG-containing cans in them The wrong oil can damage the compressor's electrical insulation.
Sealant content
Prefer cans without stop-leak sealant Sealants can clog valves and contaminate shop recovery equipment.

Brands that matter

  • A/C Pro: Widely sold DIY recharge kits with gauges.
  • Interdynamics: Maker of A/C Pro and other recharge kits.
  • FJC: Refrigerant, oils and A/C service tools.
  • Arctic Freeze: DIY recharge cans.

What to avoid

  • Hydrocarbon or propane-based 'replacement' refrigerants
  • Sealant cans in a system you may later have serviced professionally
  • Topping off repeatedly instead of finding the leak
  • R-134a in an R-1234yf system

Questions

Why won't the 134a can fit my car?

Your car probably uses R-1234yf, which has different service fittings; buy the 1234yf product.
