A/C does not blow cold air. It has frosting built on the pipe that connects to the a/c unit outside. There is some water built up where the filter sits. I turnd off the a/c for a full day, the frost melted, filter is very clean, and nothing on the inside seems abnormal. I started the a/c again after 1-day but the frost started to built up again and no cold air was blowing. (it blew cold for a few minutes only). I don't know what the problem can be. Please let me know if you have any ideas to make it function correctly again.Thank you,Shelly
