No cars "need" air conditioning. It is a personal preference of the owner. Most people would want air conditioning in their car as an option. Mississippi's hottest day was 115 degrees!
The air comes from the air outside and the air conditioning system in the car turns this into cold or warm air.
The 1939 Packard was the first car with a true air-conditioning system.
yes but you need to how much freon if may not be cost effective. Plus you need to know if it is the same type of freon.
No use for exhaust in car air conditioning
NO! You would never put propane in an air conditioning system! For air conditioning to work it needs FREON. Depending on your car you need to find out what kind of freon it requires, as well.
Automotive air conditioning is the ac unit in your car. It's what "conditions" the air in your car, ie keeping the temperature inside the car cool or warm.

I am not sure what the national chain is where you can get the air conditioning in your car serviced. Ask your car manufacture or your local garage or ask family and friends.
Fixing your Automotive Air Conditioning unit in your car will most like require you to take it to an automotive shop, expecially if it possilbe need frezon sprayed into it/.
