    As a common side effect, excess freon gas can prevent the compressor from working at its capacity.

  • Why is my car AC blowing cold and hot air?

    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.
