  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 is not heating effectively, several factors could be responsible: * A dirty filter can restrict airflow; clean or replace it. * An open door or window can let heat escape; ensure all doors and windows are closed. * If the setting temperature is too low, increase it to your desired warmth level. * Low refrigerant levels due to leakage can also reduce heating performance; check refrigerant levels and refill if necessary.

  If your Gree Air Conditioner won't start, begin by checking the power supply connection. If that's not the issue, reset the circuit breaker, as it may have tripped due to a leakage of electricity. Also, ensure the input voltage is correct. If none of these steps work, the main PC-board may be defective, and you should contact an authorized service center for repair.
