AC requires enough electrical power.

Electricity issues are also a significant reason for the AC cooling problem.

The decrease in power supply, low power supply, light fluctuate may be the common cause.

9. High Atmospheric Temperature

Any ac can control the average temperature, and the ac works effectively.

If the temperature increases beyond the maximum limit, the efficiency of the air conditioner sometimes decreases and temperature increases so much that the ac compressor stops working completely.

Solution –

If the atmospheric temperature is high in your area, then you should buy ac according to the size of your room.

Apart from that, do not let the room’s air outside, and it helps to increase the cooling level.

If the above solutions also do not fix the air conditioner, not the cooling problem, then the reason for the air filter inside the evaporator coil in the unit may also be a bit strange.

You may find it a bit strange, but it can happen if your ac is frozen.

It will make the air very hot. The ice will prevent the evaporation coils from coming in contact with the coolant and prevent the wind from cooling.

Solution –

If for some reason, ac has deposited in your evaporator coil air filter; for this, you will have to turn off your ac and clean it.
