Just like any other mechanical device air coolers are prone to wear and tear. Occasionally you may need to troubleshoot your air cooler. Before you call our Customer Care, please enter your query/complaint below to see if you can resolve the issue yourself.

Odor & Humidity

My cooler emits a strange odor

A strange odor from an air cooler is the result of either stagnant water or growth of mildew on the pads. You can resolve this problem yourself by following the simple steps mentioned below.

Change the water regularly.

Keep the cooling pads clean to keep mildew off. This should help prevent odor.

To clean the cooling pad, unplug the cooler and apply low water pressure with the help of a pipe on the cooling pad from outside.

Clean the pad at least once or twice a year.

The following steps can help you realise better cooling from your Air Cooler:

Ensure that you have switched to Cooling mode.

Ensure there is sufficient water in the tank.

Keep windows or doors open for cross-ventilation.

We recommend replacing the pads every year by registering a request on our Customer Care Helpline: +91-9510976161 Cooling pads are not covered under warranty.

Symphony Air Cooler carries a 1 year Warranty. To avail the Warranty services, please ensure you handover a photocopy of the valid Purchase Bill to the service engineer. You can also opt for our Extended Warranty for 2 years at some minimal cost.
Please check the air cooler for the above steps before registering your request.

Preventive Maintenance

To keep your Air Cooler in top condition, please check the following:

Motor and pump oiling.

Cleaning of water tank against scaling.

Cleaning of water distribution pipe / channels for even distribution of water on all sides.

Checking for any loose connections in internal electrical components. Cleaning of the submersible pump impeller and other parts for proper water flow.

Cleaning of internal / external parts of the cooler body.

Benefits of Cooling Pad Replacement

  • The life of a cooling pad is for one season only, after that evaporation is reduced.
  • The cooling pad is the only cooling media for effective cooling.
  • Choking of pads can give bad smell.
  • Choking of pads can breed germs / bacteria.
  • Choking of pads will result in less air delivery.
  • Choking of pads will result in overload on motor, thus causing more power consumption.
  • Sagging pads lead to water throwing & other problems.
  • Yearly change of cooling pad provides optimum cooling.

We recommend preventive maintenance & replacing the pads every year by registering request either on +91-9510976161 or visit us at Contact Us Cooling pads & preventive maintenance service are not covered under warranty.



An evaporative air cooler works by introducing moisture into the air and lowering its temperature. The air cooler takes in dry air, moistens it with water vapour, and releases cooled air into the room. This form of cooling is cheaper and more energy-efficient than traditional refrigeration techniques.
A standard ceiling fan rotates to increase circulation of air within a room so that the perspiration on your skin can evaporate more quickly. However, the cooling effect is limited. Fans cannot operate in closed environments and in regions where air velocity exceeds 6.4 kilometres an hour. If ambient temperatures are above the body’s natural temperature (37℃), a rotating fan will heat up the body instead of cooling it.
Air coolers, on the other hand, have a tangible cooling effect on the ambient air. By introducing moisture into the air and circulating it effectively, a Symphony air cooler can lower the room temperature significantly. While a circulating fan only affects skin perceptible temperature, an air cooler can lower indoor temperature by nearly 5℃. Air coolers work on the principle of evaporative cooling, which is a more reliable and consistent technique than circulation. Air coolers are also a lot quieter than standard fans.
Air cooling is the most energy-efficient cooling technology available. Operating costs for an air cooler are about 1/10th of a traditional air conditioner. A 2.2-ton split air conditioning unit can consume 2200 watts an hour. A Symphony air cooler consumes nearly the same amount of energy as a standard ceiling fan.
Although the energy consumption of a ceiling fan and air cooler is similar, the cooling effect is considerably different. Air coolers can cover a larger area, actually cool the air, and work noiselessly.
Although air coolers work best in dry, arid conditions, they can still provide a cooling effect as long as the humidity is below the saturation point. In other words, air coolers are effective till the air humidity reaches beyond 50%.
Air coolers may be less effective in moderately humid areas, but they can still provide ventilation and air circulation. However, air coolers are not recommended in areas with high relative humidity.
Symphony air coolers use innovative Honeycomb and Aspen cooling pads. Honeycomb pads have a unique lattice structure that resembles a honeycomb. This medium provides a superior cooling effect due to the increased surface area for transfer of humidity in passing air. Aspen cooling pads are made from shredded aspen wood fibres that are held together in a pad structure. Aspen is a completely natural material that provides 75% cooling efficiency.
Both Aspen and Honeycomb cooling pads are completely natural and highly cost-effective.
Symphony coolers come with i-Pure, a multistage filtration system that cleans a spectrum of airborne pollutants and harmful microorganisms. The cool air passes through several filters before it is released into the room. These filters can cleanse the air and water to provide a healthier indoor environment. Dust, microscopic pollution particles, bacteria, odours, and allergens are all filtered by this innovative system.
Installing a Symphony air cooler is quick and simple.
  • Start by taking the cooling unit out of the carton and remove any protective layers.
  • Depending on the model, place the cooler in front of a window or on the trolley.
  • Carefully insert the water pipe into the float valve. Keep the model disconnected and switched off while you fill the tank with water.
  • Finally, plug the unit into an electric socket nearby and switch on.
  • Place the control knob in 'cool' position or select ‘cool’ in the touchscreen and touch panel but keep the airflow option off. Wait for a few minutes till the pads get soaked with water and then start the airflow.
  • Adjust horizontal louvers and controls as per requirement
  • Keep all windows and doors open for optimal cooling performance.
The process should take a few minutes if done correctly. Please refer to the owner’s manual for more details on parts and safety.
Yes. All Symphony air coolers work on inverters. Ensure that your inverter is appropriately rated for a sine wave. Sine wave is the standard type of electricity supplied by all utility companies. All air coolers and most inverters are designed to work on this standard.
Symphony air coolers are innovative electrical devices that should not be disposed alongside other household waste. Recycling an air cooler is the most effective way of preventing harm to human health or the environment. If your air cooler needs to be discarded please contact your local authorities or the nearest Symphony dealer for details on how to discard the cooler responsibly.
