How temperature and humidity affect the car's AC performance
Updated: Sep 29
You may have noticed that the AC system doesn’t seem to work as well during a heat wave. More often than not, the outside heat simply makes the AC blow slightly warmer air and there is nothing to worry about.
Outside ambient conditions, such as temperature and relative humidity, play a critical role when we need to evaluate the performance of a car’s AC system.
In an AC system, the condenser allows heat to flow from the hot refrigerant (freon) to the cooler outside air. If the outside air is hot, the refrigerant won’t be able to cool down as much. The end result is slightly warmer air coming at your vents. Check this article for a deep understanding of "How car Air Conditioning works and removes the heat".
