* Personal injury: Refrigerant can cause frostbite or even more serious harm if it contacts your skin. The high pressure in the system is also dangerous.
* Environmental damage: Older refrigerants like R-12 are harmful to the ozone layer. Even newer refrigerants require careful handling and disposal.
* System damage: Adding the wrong type or amount of refrigerant can damage your vehicle's air conditioning system, leading to expensive repairs.
Instead of trying to do this yourself, take your Aerostar to a qualified automotive technician or a reputable air conditioning repair shop. They have the proper equipment, training, and safety measures in place to handle the refrigerant safely and effectively. They will be able to diagnose the problem (a leak is the most common reason for low refrigerant), repair any leaks, evacuate the old refrigerant (properly disposing of it), and recharge the system with the correct amount and type of refrigerant. This is the only safe and responsible way to address your air conditioning issue.
