Condensation Drain Hose: The air conditioner produces condensation as part of the cooling process. This condensation is usually collected and drained away from the vehicle through a condensation drain hose. If this hose becomes clogged, damaged, or disconnected, the water may leak into the car, causing water accumulation and water stains.
Evaporator Coil: The evaporator coil in the air conditioner is responsible for cooling the air. It is usually located inside the vehicle's dashboard. In some cases, the evaporator coil may develop leaks, allowing refrigerant and sometimes water to enter the passenger compartment.
Refrigerant Leaks: Refrigerant is the cooling agent used in the air conditioning system. If there is a leak in the refrigerant lines, refrigerant can escape into the car's interior. While refrigerant is not considered toxic, it can cause respiratory and skin irritation.
HVAC Blower Motor Area: The HVAC (heating, ventilation, and air conditioning) blower motor housing may also have potential leak points. If there are cracks or improper seals, water or debris may enter the blower motor area and cause leakage.
Poor Sealing Around the AC Unit: If there are gaps or inadequate sealing around the AC unit itself or the ducts that distribute air, water or refrigerant may leak into the car.
To prevent leaks and ensure proper functioning of the air conditioning system, it is important to have your vehicle inspected regularly by a qualified mechanic or technician. If you suspect a leak, have it diagnosed and repaired as soon as possible.
