  Michelle TerrellAug 20, 2025
  Several factors can cause a Gree Air Conditioner to have a poor cooling effect. Check the following: * Ensure the filter is clean; if dirty, clean or replace it. * Reduce the heat load in the room by decreasing the number of people or heat-generating devices. * Make sure all doors and windows are closed. * Verify that the inlet and outlet of the indoor unit are not blocked. * Lower the setting temperature. * Check refrigerant levels and refill if necessary, as insufficient refrigerant can also cause poor cooling.

  If your Gree Air Conditioner won’t start, consider these potential causes: * Check the power supply to ensure it is properly connected. * Inspect the circuit breaker; tripping may be caused by leakage of electricity. * Ensure the input voltage is adequate. * If the above steps don't resolve the issue, there may be a defect with the main PC-board; contact a service center for inspection.

  Meagan HornAug 25, 2025
  Several factors can cause a Gree Air Conditioner to have a poor cooling effect. The filter might be dirty, so try cleaning or replacing it. The room might have too much heat, so reduce the heat load. Make sure all doors and windows are closed. Check that the indoor unit's inlet and outlet aren't blocked. The temperature setting might be too high, so lower it. Finally, there might not be enough refrigerant due to a leak, so check for leaks and refill if needed.
