Why is Freon used as coolant?
Freon is the cooling agent used in most air conditioning systems. Every air conditioning system needs a refrigerant (also called a coolant) that actually creates the cool air — that’s the role of Freon.
How do you know if your Freon is low in your car?
One of the most obvious symptoms of low Freon levels is if your air conditioner is blowing warm or room temperature air. As we discussed, the air conditioning system in your vehicle operates by circulating this pressurized refrigerant. When the amount drops too low, it eventually affects performance.
