8 possible reasons behind AC not cooling properly
1. Chogged air filter - air cannot flow through properly
2. Dirty coils - condenser coils may be dirty
3. Insufficient coolant ( Gas )- when the level of this coolant becomes insufficient, the AC fails to cool.
4. Faulty compressor - If the compressor goes bad the cooling cycle does not start and the AC fails to cool.
5. Faulty thermostat - sensor that senses the room temperature and hints the compressor to start or stop the cooling cycle
6. Defective parts – fault can be in capillary , motor or capacitor
7. High atmospheric temperature - If the temperature shoots up beyond the optimum temperature limit, the efficiency of the air conditioner goes down.
8. Undersized AC - A small AC in a huge room will always find hard to cool the room in peak summers.
7 Common problems with split AC
1.Refrigerant leakage in split AC - Due to humidity and other corrosion-causing compounds in the atmosphere, these copper pipes may get weak and develop leakage holes.
2. Compressor switching off too frequently - the filter of the split AC is choked due to heavy accumulation of dust and debris. Due to this, the AC works even harder to intake air for circulation,
3. Ice accumulation on cooling coil -- When the level of refrigerant is less than the required amount, the temperature of cooling coil drops much below the normal.
4. Foul smell upon switching on the AC -- Due to dust and debris inside the drain pipe and drainage tray, water gets accumulated and slowly starts smelling bad.
5. Split AC not starting -- Well in this case, most likely the PCB of the AC unit is at fault. There’s no specific reasons to why the PCD has failed. It can be due to surges in current, too frequent ON-OFF cycles, physical damages etc.
6. Indoor unit making too much noise -- With usage the fan gets disbalanced, the technician will just dismantle the indoor unit and arrange the fan into its original place.
7. Swing mechanism not working -- there can be 2 reasons for this. The swing is controlled by separate swings motors. Either the PCB is not sending current to the motors or motors have a problem.
How to decide AC tonnage
When buying an AC, consider :
Size of your room
Tonnage of the air conditioning unit
The direction of your window
The energy that it will consume
How to calculate :
Area Method : To calculate, multiply the length and breadth of the room (in feet), take square-root of the answer and divide by 10. The resulting number will give the desired tonnage.
Volume Method : Alternatively, multiply the length, breadth and height of a room (in feet). Divide the answer by 1000. This is the tonnage required.
