Why Is Your Aircon Not Cold?
Experiencing an aircon not cold can be frustrating, especially during Singapore’s hot and humid days. At First Class Aircon, we understand the discomfort this brings and are here to help you identify the causes and provide effective solutions to restore your comfort.
Common Reasons for Aircon Not Cooling
Dirty Air
Filters
Over time, air filters accumulate dust and debris, obstructing airflow and reducing cooling efficiency. Regular aircon cleaning ensures that filters remain unobstructed, allowing for optimal performance.
Low or Leaking Refrigerant
Refrigerant is essential for cooling; low levels or leaks can result in the aircon not cold. Signs include hissing noises or ice formation on the unit. A professional aircon gas top up can resolve this issue.
Faulty Thermostat Settings
Incorrect thermostat settings can cause the aircon to blow warm air. Ensuring the thermostat is set to the desired temperature and mode is crucial. If problems persist, it may require calibration or replacement.
Dirty Condenser
Coils
The outdoor unit's condenser coils can become dirty, hindering heat transfer and causing the system to overheat. Regular aircon condenser cleaning is vital to maintain efficiency.
Blocked or Leaking Ducts
Obstructions or leaks in the ductwork can impede airflow, leading to uneven cooling. Professional inspection can identify and rectify these issues.
Electrical
Issues
Faulty wiring or components can prevent the aircon from functioning correctly. Regular aircon maintenance helps in early detection and prevention of such problems.
