Servicing an electric A/C compressor (with ND-11 oil)

Hybrid vehicles use an electric A/C compressor powered by the high-voltage system. These compressors require a special dielectric oil such as ND-11, which is specifically designed and tested for use with electric compressors. While there are many opinions online about so-called universal compressor oils, we follow manufacturer recommendations and use only the fluids specified by the factory. This helps maintain proper electrical insulation and ensures reliable compressor operation. At FIX SERVICE we perform diagnostics of hybrid A/C systems, including leak testing, vacuum procedures, and refrigerant recharge. Proper service procedures and professional equipment are essential when working with electric A/C compressors in hybrid vehicles.
