Why is my Alhafidh FHA-H54R410INV9 Air Conditioner not cooling well?
- MMichael WeaverAug 4, 2025
Several factors can cause poor cooling. The temperature setting might be higher than the room temperature, so lower it. The heat exchanger on either the indoor or outdoor unit could be dirty, so clean it. A dirty air filter can also be the culprit; remove and clean it according to instructions. Check if the air inlet or outlet of either unit is blocked; if so, turn the unit off, remove the obstruction, and turn it back on. Ensure doors and windows are closed. Excessive sunlight can generate heat, so close windows and curtains. Finally, low refrigerant due to leaks or long-term use can cause this, so check for leaks, reseal if necessary, and top off the refrigerant.
