Air coolers are popular for their affordability and lower electricity consumption compared to air conditioners. However, running them continuously can lead to overheating of the motor and wiring, particularly in older or poorly maintained units. Experts recommend that most coolers can safely operate for 8 to 10 hours if they are functioning properly. To enhance their lifespan, it is advisable to turn off the cooler for 20 to 30 minutes after extended use. Factors such as dust buildup, clogged components, and old wiring can increase the risk of overheating. Additionally, running a cooler without water can severely damage the motor and decrease cooling performance. Regular maintenance, including cleaning the fan and cooling pads, ensuring proper ventilation, and monitoring water levels, is essential for optimal performance. Users should be vigilant for signs of malfunction, such as sparks or burning smells, and consult professionals for significant issues. These precautions can help ensure that air coolers operate efficiently throughout the summer months.
