If your AC is blowing cold air outside instead of inside the house, it could be due to a problem with the air ducts or a malfunctioning air handler. This can cause the cold air to escape before reaching the inside of your home. It's best to have a professional HVAC technician inspect and repair the issue to ensure proper cooling inside your house.
The most likely cause of no air blowing out of the air conditioner is a bad fan motor. It could also be a blown fuse, electrical short, or control panel. These are a few places to start looking for the problem.
There are too many different reasons. But it seems your unit outside is not working properly.
