The main reason for the AC not cooling properly is the dirty air filter of the indoor unit. Due to prolonged use, dust accumulates in the filter and stops the air flow. Removing the filter and washing it in clean water once every two weeks increases the cooling capacity. If the cold air does not come even after the filter is clean, it should be understood that the refrigerant or cooling gas has decreased. If there are holes or leakage in the pipeline, the gas escapes, putting pressure on the compressor and increasing the electricity bill.

Outdoor units also need to be looked at. If there is dust or direct sunlight, the hot air cannot escape properly.

Besides, the AC capacity is less compared to the size of the room, but the room does not want to be cold. Again, the room can be hot even with the wrong setting of the thermostat.

For comfortable cooling, the temperature should be kept between 22 and 24 degrees Celsius. If the doors and windows of the house are open or there are gaps, cold air escapes, so it is important to keep the house sealed.

AC is running but blowing like a fan, it means the compressor is not working. Low voltage can cause compressor starting problems. In that case the stabilizer needs to be checked. First, check the air filter, temperature, door-window seals and outdoor unit for obstructions. However, in case of gas leakage, compressor failure or major wiring problem, seek professional technician help quickly.
