No use for exhaust in car air conditioning
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.
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!
changes the air temperature inside
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.
If you want to get new air conditioning for your car, I would suggest you go to ABC Auto Care in Ventura, California. Rhodes Automotive is also a good place to get air conditioning for your car.
If a 1988 Lincoln Town Car is blowing both hot and cold air when the air conditioning is on, there could be a problem with the thermostat. There might also be a problem with the level of refrigerant in the air conditioning pump.
HVAC in a car is the Heating, Ventilation and Air Conditioning system.
No. The first car didn't even have a cab.
