Soleus Air portable or window AC runs but does not cool the room effectively; air from outlet is only slightly cool.

Safety: Turn off and unplug the unit before cleaning. Do not attempt to open the sealed refrigerant system.

• Clean filters: Remove and wash all air filters with warm, soapy water. Rinse and dry completely before reinstalling.
• Clean coils: Access the front evaporator coil and rear condenser coil. Use a soft brush or vacuum to remove dust. For heavy buildup, apply a non-rinse coil cleaner following the product instructions.
• Check exhaust (portable): Ensure the exhaust hose is not kinked, crushed, or excessively long. Confirm the window kit is sealed so hot air is fully vented outside.
• Check room size and load: Verify that the BTU rating of your Soleus Air unit matches the room size. Close doors, windows, and blinds to reduce heat gain.
• Professional service: If airflow is good and coils are clean but cooling is still weak, the system may be low on refrigerant or have a compressor issue. Contact a licensed HVAC technician; refrigerant handling requires certification.
