The air conditioner suddenly stopped cooling.

1.The air conditioner remote control may not adjust the temperature. 2. It may be that the air conditioner has not been cleaned for too long, which causes dust to accumulate on the filter net, so that the cold air blocking the air conditioner cannot be blown out. 3. There may be leakage of freon in the air conditioner, resulting in too little freon, and the air conditioner is not cooled. 4. Energy saving is due to unstable voltage, which causes the air conditioner to not be cooled. 5. It may be that the number of air conditioners is insufficient, and the small number of horses is not used for cooling in a large area of the house.
