Unit is not blowing cool air / room is not cool enough

There are a number of issues that could be causing the unit to not blow cool air. Please see below for troubleshooting solutions.

• Compressor may be overheated.
  • Usually takes 30-45 minutes for compressor and internal protection to reset.
• Hot air from outside may be getting into the room through the vent. This will prevent proper cooling.
  • Inspect and check the air duct, vent and hose for proper installation or if any tears or holes are present.
  • Ensure nothing is blocking the vent.
  • Do not use extensions to the exhaust duct. The fan is not strong enough for longer lengths.
  • The vent should not be vented up towards the ceiling. Humid air may not be exhausted and is too heavy to vent out of hose.
• BTU Rating of Portable Air Conditioner is not powerful enough to cool the designated area.
  • Higher BTU cooling power is required. See our article, Cooling Area per BTU Capacity to ensure BTU Capacity is powerful enough to cool your space.
• Windows or doors in the room are open or not closed properly.
  • Make sure all windows and doors are closed.
• There may be other heat sources in the room.
  • Remove or turn off any alternate heat sources if possible.
• Exhaust air duct and hose are not connected properly or it is blocked.
  • Check duct connection and ensure it is working properly.
• Temperature setting is too high.
  • Decrease the set temperature.
• Air filter is blocked by dust and debris.
  • Clean or replace the air filter.
• The unit usually takes up to 3 minutes of operation before cooling/heating occurs. A microprocessor control delays the compressor from operating until 3 minutes have passed.
