What happens when AC runs out of Freon?

A low Freon charge can lead to compressor damage and overall inefficiencies of the air conditioning unit. This problem happens when the low refrigerant causes freezing on the evaporator coils. Eventually, the ice build-up leads to the insulation of the coils and slows the cooling process.

Why is my home AC not blowing cold?

If your central AC is not blowing cold air, the refrigerant may be the problem. The unit could be running low and need additional refrigerant added. The most likely cause of this is a leak. A leak not only keeps the AC unit from cooling properly, but also it can cause other issues within the home.
