Air conditioner not cooling3 main causes and solutions
Contents
One of the most troubling summer problems is an AC that is not cold enough, which makes it hard to sleep. Now is the best time to inspect and repair your AC so it works properly next summer!
1. The dust filter is very dirty
The exterior of an air conditioner may look clean, but a large amount of dust and dirt can be hidden inside. Leaving it uncleaned for a long time will affect cooling performance and air output.
The solution to this problem is to clean the AC regularly. If it is used frequently in summer, it is recommended to clean the dust filter and air outlet as needed. Regular maintenance helps keep the AC in ideal operating condition.
2. Condenser and evaporator fault
In addition to the dust filter and air outlet, the main components of an air conditioner also include the evaporator, compressor and condenser. If these parts are dusty for a long time or have aged, they can also affect operation and cause insufficient cooling.
If cleaning the filter and air outlet still does not make the AC cold enough, the condenser and evaporator may be the problem. However, cleaning the condenser and evaporator inside the unit is more specialised work that requires skill and experience, so it is recommended to seek help from a professional AC technician. This can ensure the unit receives complete cleaning and repair, keeping it in good working condition.
3. AC motor or refrigerant problem
Abnormalities in installation, piping connection, or the refrigerant system may affect cooling, but poor cooling does not always mean low refrigerant. A properly sealed system should not run out regularly; if there is a leak, find and fix the leak point first, then assess charging according to the manufacturer’s requirements. Residents should not connect gauges or add refrigerant themselves.
To resolve cooling problems, customers may consult a professional air-conditioning technician to inspect the cooling system. If refrigerant leakage occurs, the related repair and topping-up work must be handled by professionals.
