How to increase the cooling efficiency of the air conditioner?
To increase the cooling efficiency of the air conditioner, kindly ensure that:
1. The doors and windows are tightly shut to insulate the area.
2. The windows with direct sunlight are covered with a heavy curtain.
3. Remove any item obstructing the outdoor unit and air vents on the front side.
4. Clean the filter weekly if the unit is used for more than 8 hours a day.
How to choose a correct stabilizer for the air conditioner?
High voltage may increase the possibility of damage to the electrical parts. AC will not start if line voltage is low.
In Air conditioner, the main part is compressor which is working on 180~260 volt range. To protect it from voltage fluctuation ,use stabilizer It is recommended to use an ISI marked stabilizer of correct KVA rating as per the tonnage of the AC.
There are two types of voltage stabilizers available in market, one is Floor mount and the other is Wall mount. These stabilizers are available with digital and analog, input and output voltage reading meter. To protect the compressor there is 3 min delay start. Serial. Capacity of AC (ton) Stabilizer (KVA)
1 0.5~0.8 ton 2 KVA
2 1.0~1.2 ton 3 KVA
3 1.2~1.6 ton 4 KVA
4 2.0 ~2.5 ton 5 KVA
5 3 ton 6 KVA
How to clean the filter of the Air conditioner?
To clean the filter, unplug the power cord from the mains. Open the grille vent from the bottom or side of the unit and take the air filter out. Wash the filter under running water and wait until it is dry.
What can be wrong with the remote control of the AC if its not working?
If the remote control of the AC is not working,
1. Check if the battery is installed with correct polarity.
2. Check if you are within the radius of 10 meters from the unit with no obstacle in the path of operation of the unit.
3. If the remote control still does not work, please take it to the nearest service center.
Is it normal for a sound of water flow to be heard from the air conditioner?
It is normal for the water flow to occur right after starting or stopping the air conditioner as the refrigerant flows around the unit.
Why does not cool air come instantly when the air conditioner is switched on?
It takes approx 3 min. to have the cold air working again from the time of starting the operation to restarting the unit. It automatically starts after 3 min. It is called "3 min. delay function". This is a protection device and not a malfunction
What size air conditioner do I need to buy?
The cooling capacity of an air conditioner is measured in British Thermal Units (BTU), and the capacity you require depends on the size of the room you need to cool. If you buy an air conditioner that is too small for the room it will not cool adequately. If you buy one that is too large, the air conditioner will cool the room before it dehumidifies.
Cooling capacity of an air conditioner is measured in tons so one ton AC provides 12000 BTU in one hour.
To find out which size unit is best for the room, divide the size of the room (length*breadth*height) by 1000 . It will give the ton capacity. The table below will make this task easier for you:

Make any adjustments for the following circumstances:
If the room is heavily shaded, reduce capacity by 10 percent.
If the room is very sunny, increase capacity by 10 percent.
What is the electrical consumption of the air conditioner per month?
It depends on the air conditioner model you are using and the usage pattern.
The estimated electrical consumption can be calculated by:
Estimated Electrical Consumption = Input (kW) X No. of hours used X No. of days per month X Current Electricity Rate
Why is the room not cool enough even after the air conditioner running for awhile?
It may be due to the following reasons:
1. The indoor fan coil is dirty resulting in weak dissipation of cool air.
2. The outdoor condenser is dirty and not producing cooling refrigerant
3. There may not be enough refrigerant in the air conditioning system.
4. The desired operating temperature is set too high.
5. The air conditioner installed is under-sized.
The proper room size is 10`L X10`W X10`H for 1 Ton Air-con.
In a 10 feet high room, a split type AC should be installed at 7 -8 feet for the best cooling performance. For a window type AC, the best height is 3-4 feet from the floor. If you are fixing the AC very close to the wall or in an airtight room it will trip due to high head pressure, as heat dissipation can't happen. Distance must be more than 900 mm after fixing the air-con and top of the shaft should not be closed.
How to check star rating of an Air conditioner
The star rating is provided for customer awareness by BEE (Bureau of Energy Efficiency.) Depending on the energy efficiency, air conditioners are rated on a scale of 1 to 5. Higher the star rating, lesser the power consumption.
EER is calculated by :
Cooling capacity (Watts) / Power Consumption (Watts)
For example:
One 1.5 ton AC with 5275watts cooling capacity and 1650Watts power consumption, so EER of unit is 5275/1650=3.1 EER with star rating 4.
EER is calculated by :
Cooling capacity (Watts) / Power Consumption (Watts)
Is regular air conditioner service a benefit?
Regular service of the air conditioning equipments will provide the following benefits:
1. The air conditioner will cool better
2. The electrical consumption of the air conditioning equipments will be lower
3. Air conditioner leaking will be minimized.
4. There will be less need for air conditioner repair.
Warranty - what is covered?
Check the Instruction Manual that comes with the product. Most manufacturers warranty all parts and labour for one (1) year from date of sale and 5 years for compressor for normal usage. Cosmetic parts, like the filter, grille or knobs, are usually not covered
