The most important part of a car’s air conditioning system is the refrigerant. This liquid coolant absorbs heat from the air inside your car and releases it outside. The refrigerant is then recirculated back into the AC unit to continue the cooling process.
There are different types of refrigerants, but the most common one used in cars is R-134a. It’s important to make sure that your car’s AC system is properly charged with this type of refrigerant in order for it to work correctly.
If you notice that your car’s AC isn’t blowing as cold as it used to, it could be because there’s a leak in the system. A certified mechanic can check for leaks and recharge the system if necessary.
