Amana air conditioner runs but does not cool the room effectively; air from vents is only slightly cool or room temperature.

Safety first: Turn off and unplug the unit or shut off the breaker before cleaning or opening panels.

Steps to improve cooling performance:

• Clean or replace air filter: Remove the front grille, take out the filter, and clean or replace it according to the manual.
• Clean coils: Access the indoor (evaporator) and outdoor (condenser) coils. Use a soft brush and vacuum to remove dust and lint. For heavy buildup, use a non-acidic coil cleaner.
• Check airflow: Ensure supply and return air paths are not blocked by furniture, curtains, or covers. Verify the fan runs at full speed.
• Room sizing: Confirm the BTU rating of the Amana unit matches the room size. An undersized unit will never cool adequately.
• Call a technician for refrigerant issues: If coils and filters are clean and airflow is good but cooling is still weak, a refrigerant leak or compressor problem is likely. A licensed HVAC technician must diagnose and repair the sealed system.

Do not attempt to pierce or open refrigerant lines; this is dangerous and requires certification.
