Air conditioners use the physical properties of compressing gas into liquids and letting these liquids decompress back into a gas.
When you compress a gas into a liquid, heat is formed.
When you decompress this liquid, cold is formed.
Your AC compresses gas outside the house (makes heat) and then lets the compressed gas (liquid) enter into the house side of the AC. On the house side, the liquid is decompressed (makes cold). The decompressed gas goes back outside the house and the process is performed over and over again.
Your engine is hot.
The AC isn't working.
your car ac will only blow hot air when there coolannt in the car is finished or the car is oveerheated.
If your ac is making noises or is blowing hot air instead of cold
Need to add Feron.
It may have a bad heater core.
There are three main possible causes to explain why a car air conditioner is blowing hot air. These causes are a worn out compressor, refrigerant leak, and an electrical problem.
Low refrigerant charge? Temperature contro set to HOT position?
Clutch possibly not engaged compressor maybe.
AC System probably needs refrigerant added.
If the AC control is always blowing hot air, the AC control head has failed.
low refrigerant charge?
