2. What is the estimated electrical consumption of an air conditioner per month?

The estimated electrical consumption can be calculated by using the following formula:
Estimated Electrical Consumption = Input (kW) X No. of hours used X No. of days per month X Current Utility Rate.

3. What is the average life span of a residential air conditioner?

Generally, the average life span of any air conditioner is six to seven years. This is subjected to usage pattern and regular servicing of the air conditioner by a qualified air conditioner technician.

4. What is an Inverter air conditioner? Is this more efficient than a non-Inverter conventional air conditioner?

An Inverter air conditioner delivers cool air by varying the frequency of the compressor, and thus regulates the refrigerant to satisfy room cooling requirements and achieve the desired temperature with minimal fluctuations. It eliminates waste with precise control. In this way, it is more energy efficient.

  • 8. The air conditioner does not start operation immediately after it is turned on?

    To reduce excessive load in a restart, the air conditioner compressor does not operate for three minutes when the ON switch is pressed immediately after it is shut down or when the operation mode (setting) is changed using the remote controller.

    9. The air conditioner does not blow air immediately after it starts operation in the heating mode?

    The air conditioner conducts a "warm-up" operation first so that it won't blow cold air in the heating mode. The fan starts operating after one to four minutes of warm-up operation. (The warm-up operation becomes longer when the outside air temperature is low.)

    10. The air conditioner produces a water flowing sound?

    The water flowing sound is produced by the refrigerant that flows inside the air conditioner. This sound is more prone to generation when the defrost operation is activated in a heating operation.

    11. The air conditioner produces an air releasing sound.

    The air releasing sound is caused by a change of the refrigerant flow direction. This sound is generated when the air conditioner stops operating or the defrosting operation is activated in a heating operation.

    12. The air condition produces a crackling sound?

    Plastic parts such as the front panel produces a crackling sound when they expand or contract slightly due to temperature change.

    13. The outdoor unit discharges water or steam?

    The defrost operation activated in the heating mode removes frost, which turns into water or steam. A small amount of water is also discharged during a heating operation.

    14. The amount of drained water is very high?

    The amount of drained water varies depending on room temperature and humidity. A large amount of drained water does not denote a malfunction.

    15. The air conditioner does not operate (Operation lamp is not lit).

    Check the following:

  • Make sure the circuit breaker is not turned off and the fuse is not blown.
  • Make sure the power cord plug is connected securely to the service outlet.
  • Make sure the remote controller has new batteries.
  • Make sure the timer is not programmed mistakenly.
  • 16. The air conditioner does not cool or warm the room?

    Check the following:

  • Make sure the set running mode must be Cool/Heat from remote control.
  • Make sure the air filters are not dirty.
  • Make sure the air flow and direction settings are appropriate.
  • Make sure the temperature setting on the remote controller is appropriate.
  • Make sure the air inlets and outlets of the indoor and outdoor units are not blocked by objects.
  • Make sure ventilation fans in the room are not operating.
  • Make sure the doors and windows are closed.
  • 17. The air conditioner stops operating (Operation lamp blinks)?

    Check to see if the air filters are clean. Also make sure the air inlets and outlets of the indoor and outdoor units are not blocked.Pls refer manual for more detail

    18. The indoor unit produces a mist?

    The cold air blow out during a cooling operation reduces the temperature of the room air and sometimes generates a mist.

    19. The air conditioner stops suddenly during operation

    When power supply voltage fluctuates largely, the air conditioner may stop operating to protect the equipment. (When power supply returns to a normal condition, the air conditioner resumes operation after three minutes.)

    20. The air conditioner stops in the middle of operation (ON timer in operation)?

    When the ON timer is set, the air conditioner may start as early as one hour before the set time in order to bring the room temperature close to the temperature set with the remote controller. If the remote controller is operated (except ON/OFF operation) during this time period, the air conditioner enters the stop mode. When this happens, turn on the air conditioner using the remote controller, and set the timer again.

    1. What is an Evaporative Air Cooler?

    An Air Cooler works on the principle of evaporative cooling process. When warm air is drawn into the cooler, it passes through a wet Honeycomb/WoodWool Cooling Media. As it passes through, it mixes with the water held in the Honeycomb/WoodWool Cooling pads, causing the water to evaporate and lose heat, resulting in cool & moisturized air. A powerful fan then propels the cool air into the room (or outdoor area, if outdoors). The result is a constant flow of fresh, moisturized, cool air while old and stale air is circulated out of the room.

    2. Why does evaporation cause lower temperature?

    The temperature of dry air can drop significantly when liquid water transforms to water vapor (through evaporation). Water always has lesser temperature than air called dew point temperature. So, water evaporates by taking heat energy from warmer air which mixes with it & hence it results in temperature drop.

    3. How is a room air cooler different from a fan?

    Normal fans use fan blades to circulate air around the room without offering any cooling. Room Air coolers use the natural process of water evaporation to cool incoming hot air and use a powerful fan to evenly distribute newly cooled air. The temperature of dry air can drop significantly when liquid water transforms to water vapor (through evaporation).

    4. What are honeycomb cooling pads and how are they different from conventional wood wool pads?

    The honeycomb cooling pads are more durable and also provide uniform cooling. Moreover, they do not allow dirt & sediments to deposit on the pads. Hence, it gives cool & fresh air.

    5. How do I select the right type of room air cooler (Personal, Desert, Window or Tower)?

    Desert Cooler – if the room size is big (>250 sqft) and climate is dry & hot.

    Window Cooler - if the room size is big (>250 sqft) and climate is dry & hot. The window cooler comes with a trolley which can be used under multiple applications.

    Personal Cooler – If the room size is small (<150 sqft) and the climate is humid or temperate. It is mostly used for personal or spot cooling.
