Why is my Gree Air Conditioner not cooling properly?
- M
  Michael AllenAug 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.
