If you feel your AC is not cooling enough, it could be because too much dust has accumulated overtime. When AC vents are left unclean for long, the evaporator coil tends to collect dirt, dust and moisture. This becomes a favourite breeding spot for bacteria and fungi that spread throughout the car. Moreover, unclean AC vents can spread bad odour in the car, which keep circulating for long. The 3m AC treatment rids the car of dust, dirt, pollen and damp air. It ensures that fresh air is circulated from the AC and the coolant works well.
