1. Refrigerant Leakage in Concealed Ceiling Air Conditioners
After turning on the air conditioner for about 15-30 minutes, if you still don't feel cold air coming out from the indoor unit, it could be due to refrigerant leakage. The efficiency of concealed ceiling air conditioners largely depends on the refrigerant level. Therefore, both shortage and excess of refrigerant can affect the unit's performance.
Refrigerant leakage in concealed ceiling air conditioners can be caused by various reasons: improper installation and maintenance by technicians resulting in leaky pipes; deterioration of pipe material over time leading to pipe cracks; lack of regular maintenance; undersized air conditioners for the room size causing the unit to operate overloaded, consuming excessive refrigerant.
To rectify the issue, check the refrigerant pipes for sagging, leaks, punctures, or cracks. If found, replace the pipes. If the pipes are intact, you may need to refill the refrigerant.
2. Noisy Operation of Concealed Ceiling Air Conditioners
The noisy operation of concealed ceiling air conditioners disrupts the peaceful ambiance, directly affecting users' sleep. The causes of this condition include: malfunctioning compressor and fan system; degraded unit; internal components collision; improper installation...
Solution: Most causes of noisy concealed ceiling air conditioners originate from internal components. Therefore, you cannot rectify them without expertise and knowledge in HVAC.
3. Outdoor Unit Blockage in Concealed Ceiling Air Conditioners
Symptoms of outdoor unit blockage in concealed ceiling air conditioners include: air blowing out but not cold, copper pipes covered in frost, loud noises, continuous on-off cycles of the outdoor unit.
Causes of outdoor unit blockage in concealed ceiling air conditioners include: malfunctioning of the thermal relay in the outdoor unit due to compressor motor failure, capacitor failure, weak or faulty outdoor unit fan; loss of power supply to the compressor in the outdoor unit due to faulty circuit board, broken power cable connecting to the indoor unit, or faulty thermostat switch; overload operation leading to motor burnout or circuitry failure.
To fix this issue, you need expertise in HVAC. If you don't have it, it's best to contact the warranty center or an air conditioning repair shop for quick and safe resolution.
4. Faulty Temperature Sensor in Concealed Ceiling Air Conditioners
The temperature sensor in concealed ceiling air conditioners is responsible for detecting human presence and adjusting room temperature. Therefore, when this component is faulty, it affects the cooling ability of the device.
Causes of a faulty temperature sensor in concealed ceiling air conditioners include: high room temperature causing thermal sensor wires to degrade; improper usage such as continuous 24/7 operation, setting the temperature too low, frequent on-off cycles; accumulation of dust and dirt causing sensor blockage; sensor wires being bitten or severed...
Solution: It's essential to clean the unit regularly, preferably every 3-6 months; if the issue is related to damaged temperature sensor wires, contacting the warranty center is advisable.
5. Continuous Operation Without Cooling
Concealed ceiling air conditioners running continuously but not blowing cold air may be due to several reasons: failure to clean the unit's air filter; non-functioning fan blades in the outdoor unit causing air stagnation; undersized concealed ceiling air conditioner for the room size.
Solution: Clean the unit's filter regularly, ideally 2-4 times per month; replace the fan motor or outdoor unit fan blades; choose an air conditioner with appropriate capacity for the room size as recommended by the manufacturer.
