If your Portable Air Conditioner is not blowing cold air please check the following:

• check that the unit temperature setting is lower than the room temperature;
• check that the fan is blowing warm air from the back of the unit;
• check that you hear the compressor kick on after start up (could be a 3 minutes delay);
• check that the filter is clean and unit has not error messages.
