1. The system is low on freon or its empty......
2. The a/c coil is bad..

A split air conditioner is a unit where the condensing unit is outside and the evaporator is inside.
An air conditioner uses refrigerant to transfer heat from one place to another, such as from inside the home to the outside.
If your air conditioner is running outside by not blowing cold air inside through your vent, your indoor coil is frozen. You will need to turn everything off and allow the unit to thaw out.
you might need freon in the air condition.

Because while your air conditioner is activated the air from outside is coming in being purified and is then released so its like a vacuum of some sort!
A ductless air conditioner consists of two main components. These are a unit mounted on an inside wall that delivers the cool air to the room, and a unit mounted on the outside of the house.
There are 2 coils. 1 inside the indoor air handler or furnace and 1 outside on your condenser in the yard.
Most of the ones that I have seen have dirty condensor coils. That's the coil you see from the outside. They get dirty on the inside of the air conditioner where the fan blows air through it.
An air conditionerÕs function is to take the hot air inside the enclosed space and release some of it outside while blowing a cool air in the room that is converted from the hot air. This process is being done repeatedly by heat exchangers found inside the air conditioner.
In any other setting than full recirculation the system mixes inside and outside air. on max cool or full recirc. all vent to the outside are or should be closed.
is your fan running in the correct direction? are any of your ducts blocked?
