The common sign that your unit has low refrigerant is the unit failure to cool the room. Low refrigerant can also cause the unit to start and stop often. Frost on aircon evaporator fan is also a sure sign that there is a problem with the refrigerant.
Another factor that can make the unit fail to cool the room is freezing up of the AC evaporator.

Nevertheless, simply topping up of aircon gas may not solve warm aircon problem. There are other issues that can cause warm aircon problem. Some of the problems are;
If your unit AC fan is blowing, but it is not blowing cool air, the problem can be the thermostat. It is good to ensure the thermostat is set for cooling and the fan is also set to automatic.
