Air coolers are a popular and energy-efficient way to stay cool during hot weather. However, like any appliance, air coolers can occasionally experience issues. Fortunately, many common air cooler problems can be easily diagnosed and fixed without professional help:

Insufficient cooling performance

The most common complaint about air coolers is that they do not cool the room effectively:

• Water levels: Air coolers rely on water to cool the air through evaporation. If the water tank is empty or low, the cooler cannot perform correctly. Check the water levels and refill the tank if necessary.
• Water distribution: Ensure that the water distribution pads are evenly soaked. Sometimes, water distribution can be uneven if the pads are clogged or the water pump malfunctions. Clean the cooling pads and the pump to ensure proper water flow.

Strange noises or vibrations

If your personal air cooler starts making unusual noises or vibrations:

• Loose parts: Over time, fan blades or water pump components can become loose. Check to see if any parts are wobbly or out of place. Tighten any loose screws or cooler parts to fix the vibrations and sounds.
• Blocked water pump: A clogged water pump makes a strange noise. Turn off the cooler and inspect the pump. Clean any stubborn gunk or dirt that may have accumulated inside.

Water leaking from the cooler

If you notice water leaking from your air cooler, it creates a mess and affects its cooling efficiency:

• Check the water tank: Ensure that the water tank is seated correctly and there are no cracks or damage. A cracked water tank leads to leakage, and if it is damaged, you may need to replace it.
• Check the hose or tubes: Your air cooler may have a water hose or tube connecting the water tank to the pump. Check the tube for cracks or blockages that cause leakage. If necessary, replace the hose or clean it.

A foul odour coming from the cooler

Sometimes, air coolers can produce a musty or unpleasant smell, especially if not cleaned. This odour is usually caused by stagnant water or mould growth inside the cooler:

• Clean the water tank: Empty the water tank and thoroughly clean it with a mild disinfectant or a mixture of vinegar and water. This eliminates bacteria and mould that causes the odour.
• Clean the cooling pads: Dust and moisture buildup can cause mould to form on the water distribution pads, particularly in desert coolers. To make sure no bacteria or mould grows on them, remove the pads and give them a deep and regular cleaning.

Conclusion

Regular maintenance, such as cleaning the water distribution pads, checking the water levels, and ensuring proper ventilation, prevents these problems from occurring. However, if you do experience issues, consulting a professional or a plumber to ensure your air cooler is functioning efficiently may be a good idea.
