What is the standard temperature for car air conditioning vents?
2 Answers
There is no standard temperature for car air conditioning vents. In cooling mode, a vent temperature around 10 degrees Celsius is considered normal. If the vent temperature is too high, it indicates poor cooling performance in the air conditioning system. Possible causes of poor cooling include unrefrigerated refrigerant for a long time, damaged compressor clutch, or a faulty compressor. Below are some considerations for selecting air conditioning temperature: 1. Some people set the temperature very low for quick cooling, which may feel refreshing. However, this can disrupt the body's endocrine system regulation. 2. Excessively low indoor temperatures, such as below 20°C, can cause various discomforts like leg soreness, general fatigue and chills, and headaches. If there are elderly or children in the car, it's better to set the temperature at around 27°C. 3. Normally, the cabin temperature should be about 5°C to 6°C different from the outside temperature, so it's advisable to adjust the temperature based on the external weather conditions.
Speaking of the standard temperature for car air conditioning vents, with over a decade of experience running an auto repair shop, I've seen countless cases. Generally, the temperature should be between 8 to 15 degrees Celsius to be considered normal, ideally about 10 degrees lower than the outside temperature. For example, when it's 35 degrees outside, the vent temperature should be below 10 degrees. But this isn't a hard rule—different cars and environments can vary. New cars with good cooling might get close to 8 degrees, while older cars or during extremely hot days might hover around 15 degrees. If the temperature consistently exceeds 15 degrees, there's likely an issue, such as refrigerant leakage or a failing compressor, and you should confirm with a thermometer. I always remind car owners to check their AC systems before summer—proper maintenance saves fuel and ensures safety. Never ignore minor issues; it's miserable if the AC fails during a long trip.
