Step-by-Step Guide to Maintain Your Air Cooler

1. Clean the Cooler Before Summer Starts

Before using the air cooler for the first time in the season:

Unplug the cooler: Always switch off and unplug before cleaning.
Open the panels: Remove side or back panels as per the design.
Clean the inside: Use a dry cloth or vacuum to remove dust and dirt.
Wash the water tank: Use mild soap and water to clean the tank. Rinse well.
Inspect wires and switches: Make sure there are no loose wires or damage.

Doing this at the start of summer helps you avoid smell and ensures smooth operation.

2. Clean or Replace Cooling Pads

Cooling pads play a big role in how well your cooler works. They absorb water and allow hot air to pass through, making it cool.

Clean monthly: If your cooler has wood wool (grass) pads, clean them once a month.
Replace pads: Replace cooling pads every year if they are very dirty, torn, or have mold.
Use honeycomb pads: They are long-lasting and give better cooling.

To clean:

Remove the pads.
Use a brush or hose to clean dust and dirt.
Let them dry fully before placing back.

3. Clean the Water Tank Regularly

Stagnant water can lead to the growth of bacteria and algae, causing a bad smell or even making you sick.

Clean every 3-5 days if you use the cooler daily.
Use a mild detergent or vinegar and scrub the inside with a soft brush.
Rinse thoroughly to remove all soap or cleaning solution.

If your area has hard water, you may also see white stains or scaling. Use a descaling solution once a month to remove these deposits.

4. Use Fresh and Clean Water

The quality of water you use in your cooler affects its efficiency and smell.

Use clean tap water or filtered water if possible.
Avoid using stored water that has been sitting for days.
Refill the tank with fresh water daily or every two days.
Drain out old water fully before refilling.

Fresh water ensures better evaporation and prevents bacterial growth.

5. Check the Water Pump

The pump is the heart of the air cooler. It circulates water to the cooling pads.

If water is not flowing evenly over the pads, check the pump.
Clean the pump with a brush and make sure it’s not clogged.
Ensure that the pump is fully submerged in water when running.
If the pump is not working even after cleaning, you may need a replacement.

A smooth-running pump means better cooling and less strain on the motor.

6. Maintain Proper Airflow

Good airflow is necessary for effective cooling.

Place the cooler near an open window or door for proper air circulation.
Make sure there’s space behind the cooler for air to enter.
Clean the fan blades and motor cover to remove any dust.
If the fan is making noise, apply a few drops of machine oil to the motor bearings.

Also, clean the fan grill and outer surface regularly with a damp cloth.

7. Use Ice for Instant Cooling (Optional)

Adding ice to the water tank gives a quick cooling boost, especially on extremely hot days.

Use crushed ice instead of large blocks.
Don’t use too much ice—it can slow down the water flow and affect the pump.
Only use ice occasionally. For regular use, cool water is enough.

This is a temporary trick, not a permanent solution for better cooling.

8. Cover the Cooler When Not in Use

When summer is over:

Drain all water from the tank.
Clean the cooler one final time.
Let it dry completely to prevent mold or rust.
Cover it with a cloth or plastic sheet to protect it from dust during storage.

Storing your cooler properly will help it stay in good shape for the next summer.

Extra Tips for Better Efficiency

Use the cooler in dry heat: Air coolers work best in dry, low-humidity environments. In very humid areas, cooling may not be effective.
Add a small fan: If your cooler is not covering the whole room, a ceiling or table fan can help spread cool air faster.
Check for leaks: If water is leaking from the tank, check for cracks or loose pipe fittings.
Don’t overload power: Avoid using the cooler with other heavy appliances on the same plug point.
Use stabilizer (if needed): In areas with voltage fluctuation, a stabilizer can protect the cooler’s motor and pump.

Common Mistakes to Avoid

Not cleaning regularly – Leads to bad smell and poor cooling.
Using dirty or hard water – Causes scaling and damages parts.
Running cooler on empty tank – This can burn the water pump.
Ignoring strange noises – May lead to motor or fan failure.
Not replacing old pads – Reduces cooling and air quality.

Avoiding these simple mistakes can keep your cooler working well for many years.

How Often Should You Maintain?

Here’s a quick maintenance schedule:

Task	How Often
Full cleaning	Start & end of summer
Water tank cleaning	Every 3–5 days
Cooling pad cleaning	Every 2–4 weeks
Cooling pad replacement	Once a year (or as needed)
Pump and motor check-up	Monthly
Outer body cleaning	Weekly

Following this schedule ensures your cooler stays fresh, hygienic, and effective.
