Many people ask if their car’s A/C needs more Freon to help it cool better. Freon is a brand name for A/C refrigerant (the Kleenex of refrigerant). Having a low level of refrigerant can be a reason for an underperforming A/C, but it is also a symptom of a problem.
Here are 3 signs that your vehicle may need refrigerant:
1) If you notice that your A/C isn't blowing as cool as it used to, that could be a sign that your refrigerant is low and needs to be re-charged. Low refrigerant levels cause your vehicle's A/C components to not work as effectively as they are designed.
2) If you notice a hiss or high-pitched hum noise from under the dash, it is possible that the A/C has low refrigerant. When there is not enough refrigerant in the system some vehicles will make an audible noise under the dash. This noise is from a low level of refrigerant rushing through the vehicle's expansion valve.
3) If you can see visible leaks or oily residue on A/C lines or components. Refrigerant is a gas that will not leave a stain, but the oil and refrigerant dye suspended in the refrigerant can leave visible traces of a leak.
It is important to remember that your vehicle needing refrigerant is a sign that there is a leak present. A/C systems are sealed. Adding refrigerant to a system that is leaking is only a temporary fix and can do more harm than good. Refrigerant leaking from your vehicle and escaping into the air is not only a cause of discomfort it is also detrimental to our environment. A/C repairs should only be done by licensed professionals using the required recovery and recycling equipment.
