Most A/C systems stop working because of low refrigerant. When we recharge your system, we also inject dye to identify any source of leak your vehicle may have. When we use an ultra violet light it illuminates the compromised component in bright yellow. Just charging your system when it is low is environmentally irresponsible and illegal.
We have recently upgraded our A/C service machine with a Robinair 34788 to be able to handle hybrids and vehicles with electric ac compressors. It meets the new SAE J2788 standard. Along with new safety standards, it also allows us to handle refrigerant in a more environmentally friendly manner.
