Why does my AC suddenly started blowing hot air?
When AC is blowing warm air, the most common cause are low freon levels. Due to the lack of freon, there the freon expansion (turning it from liquid to gas) is not sufficient. That means the cooling coil will not be adequately cooled; in fact, it might start to become warmer the longer we run the AC.

Why does my car AC go hot and cold?
If your A/C flip-flops from hot to cold and back again, your expansion valve could be failing. The expansion valve removes pressure from liquid refrigerant to allow expansion from a liquid to a vapor state in the evaporator. If the valve is blocked, the refrigerant flow could be restricted or could be too unrestricted.
