Understanding the Basics of Car Air Conditioning
Before we dive into the possible causes of hot air blowing from your car’s AC, it’s essential to understand how car air conditioning works. The AC system in your car uses a refrigerant to cool the air, which is then blown through the vents. The refrigerant absorbs heat from the air and transfers it to the outside of the car, where it’s released. The AC system also uses a compressor, condenser, and evaporator to circulate the refrigerant and cool the air.
The AC system in your car is a complex network of components that work together to provide a comfortable driving experience. However, when one of these components fails or becomes clogged, it can cause the AC to blow hot air. In this section, we’ll explore the possible causes of this issue and what you can do to fix it.
