Types of window air coolers

How to choose the right window air cooler

Choosing the right window air cooler depends on several factors:

  • Room size: Larger rooms need higher cooling capacity (measured in CFM – cubic feet per minute).

  • Climate: Window air coolers work best in dry climates; for humid areas, look for models with humidity control.

  • Water tank capacity: A larger tank means longer cooling without frequent refills.

  • Cooling pads: Honeycomb pads offer better cooling efficiency than traditional wood wool pads.

  • Energy efficiency: Look for low power consumption to reduce electricity bills.

  • Installation compatibility: Ensure the cooler fits your window frame and has easy mounting options.

Maintenance tips for window air cooler

  • Regular cleaning: Clean the cooling pads, water reservoir, and exterior surfaces of the cooler regularly to prevent the buildup of dirt, dust, and mineral deposits, which can affect performance and air quality.

  • Water quality: Use clean and preferably filtered water to fill the cooler's reservoir to avoid clogging the pads and internal components with sediment or impurities.

  • Seasonal maintenance: Perform seasonal maintenance tasks such as flushing the water lines, lubricating moving parts, and checking for leaks or damage to ensure optimal performance during peak cooling seasons.

  • Airflow optimisation: Position the window air cooler near an open window or door to facilitate proper airflow and ventilation, maximising cooling effectiveness while preventing the buildup of humidity indoors.

  • Professional servicing: If the cooler experiences issues such as reduced cooling capacity, unusual noises, or mechanical malfunctions, seek professional servicing to diagnose and rectify the problem promptly.
