Hi, I have the same problem. I handle it by dropping the temperature setting to 16C - the lowest setting - until it blows cold, then raising the temperatire until it holds well. I have the same problem with it blowing cold and I want warm. I raise the temp to its max - 32C in Canada - then dropping it down to around 26C. Good luck.
