What is this high pitched sound my AC unit is making?
This started about a week ago. Starts around 5 minutes before the AC turns on and then after it turns off it lasts anywhere from 5-30 minutes. Seems to go away when the AC is running. If I turn the unit off while it’s making this sound, the sound continues. AC still blows cold air and works properly. Thoughts??
