It's perfectly fine to run the air conditioning, brand new or not.
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.
It is not a good idea to try and fix the air conditioning in your car yourself. Try going to a mechanic or car repair shop to have your car air conditioning properly fixed.
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.
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 use for exhaust in car air conditioning
The purpose of the AC vent hose in a car's air conditioning system is to carry cold air from the air conditioning unit to the vents inside the car, allowing the cold air to be distributed throughout the interior of the vehicle.
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.
I would go with Carrier. I have lived in Florida all my life and I am very familiar with heating and cooling using central air. I also use air conditioning in my car.
Any air shocks are good and will work on your car.
