Central air conditioning is an essential home comfort system in Gulf countries like Kuwait, where temperatures reach extremely high levels during the summer. Despite this importance, some common faults can hinder the efficient operation of these systems. In this article, we'll review five of these common faults and how to fix them, with advice from an air conditioning technician in Kuwait.
1. Low cooling efficiency
- Clean or replace filters: Air filters are essential components that must be cleaned regularly to ensure cooling efficiency. Dirty filters reduce airflow and make the system work harder; therefore, it is recommended to clean them every two months or replace them if necessary.
- Refrigerant Check: Sometimes, a cooling efficiency issue may be caused by a refrigerant (Freon) deficiency. Checking Freon levels and refilling it, if necessary, should be performed by a qualified technician.
- Condenser and evaporator inspection: Dirt and dust buildup on the condenser and evaporator can lead to reduced efficiency. Regularly cleaning these components can improve the unit's performance.
2. Water leakage
- Cleaning drain lines: Water leaks are often caused by clogged drain lines. Cleaning them regularly can prevent this problem.
- Check the collection tray: The collection tray under the unit must be clean and free of any blockages to prevent water from accumulating.
- Checking seals: Confirming that there are no leaks in the seals and connectors of the indoor and outdoor units may help prevent water leaks.
3. Unusual noise
- Check the motor and fan: Noise often comes from the motor or fan inside the unit. Ensuring they are not worn or in need of lubrication may reduce the noise.
- Installing the unit: Ensure that the unit is securely installed and that all screws and bolts are in place, which can dampen the sound.
- Insulation Check: Checking and improving the sound insulation around the indoor and outdoor unit may help reduce noise as well.
4. Random device shutdown
- Electrical check: Make sure there is a good electrical connection and that the fuses and breakers are not damaged.
- Thermostat Programming: Sometimes, the thermostat can cause the unit to shut down unexpectedly. Checking and adjusting the thermostat settings correctly may solve the problem.
- Thermal Protection Check: Central air conditioning units often contain switches that cut off the unit when the temperature rises. Checking these switches may be necessary.
5. Bad smell
- Cleaning pipes and drains: Musty and damp odors are often caused by bacteria and mold buildup in pipes and drains; regular cleaning can help.
- Check and clean the heat exchanger: The heat exchanger may accumulate d
