The evaporator is a vital part of the car AC system. So it absorbs heat from the cabin and cools air effectively. Then dirt dust and moisture collect on its surface over time. That buildup lowers efficiency and reduces cooling strength during long drives. A dirty evaporator forces the system to work much harder. So energy use increases while cooling comfort falls inside the cabin. Then regular cleaning restores balance and protects the entire system from stress. A clean evaporator always keeps cooling strong and steady in every season. Why Evaporators Collect Dirt The evaporator sits deep inside the AC...
