Is It Normal for a New Car to Drip Water When the Air Conditioner Is On?

[McBryce]

Normal. Here is the relevant information: Condensation water: This water is condensation from the air conditioner. When the air conditioner is cooling, the temperature of the evaporator and the air ducts leading to the passenger compartment is very low, usually around 0~5 degrees Celsius. Water vapor from the outside air will liquefy and condense on the walls of the air conditioner's pipes and casing at such low temperatures. If there is no way to drain it, it can cause moisture around the air conditioning system (inside the dashboard) and corrosion of components. Normal phenomenon: Therefore, when designing a vehicle, drainage pipes are included to collect and discharge the condensation water. The outlet to the outside is usually located directly below the center of the dashboard, which, when projected to the underside of the car, is roughly at the front of the transmission. So in the summer, if you start the engine, turn on the air conditioner, and leave the car parked for a while before driving off, you will often see a puddle of water on the ground. This puddle is the result of water vapor in the air condensing due to the cold, which is a normal phenomenon.
