Working of air conditioner and easy maintenance steps

Indoor and outdoor unit come with central air conditioning system. They both work in coordination to keep cooling inside the home or room. The cooling is actually done by transferring the heat. The heat transfer leaves inside air cool.

Outdoor unit –

The main function of the outdoor unit is to disperse the heat from the room. The part of the unit are compressor, fan and condenser coil. The heat sucked from the room is transferred to the refrigerator and then pumped to the outdoor unit.  This heat passes through compressor before moving to the outdoor unit. The compressor moves the refrigerant throughout the system. This movement of the refrigerant is important as it keeps the air inside the room cool. This refrigerant moves to the condenser coil, as it is pressed at high pressure. When refrigerant moves through condenser, the fan delivers the air across the condenser coil, making it cool. This process continues with air inside the home moves to outside unit for dispersion.


The indoor unit –

It unit contains a evaporate coil, which evaporates the refrigerant. This refrigerant absorbs the heat of the room. Once heat is absorbed, the cool air comes to take the place and cooling the room in the process. The cooling of the house is actually more about removing the heat and less about giving cooling air inside the room.

In window AC Installation Services in Dwarka air conditioner system, the unit is fitted on the window. The front side contains evaporated coil and throws cool air. The back side of window air conditioner works as outdoor unit and disperse heat outside the room. Split air conditioners can be used in room, without any window. But the outdoor unit has to be connected with the inside unit.


Maintenance steps –


Cleaning of air conditioner should be done whenever it is possible to do so. The filters must remain AC Repair & Services in Dwarka Delhi clean for fresh air circulation. The accumulated dust reduces the efficiency of the air conditioner system to effectively cool the room. The drainage pipe is other part of the system, which can be cleaned and checked easily.  The owner must ensure that place to be cooled has to be properly closed. The door and windows of the room must remain close for effective cooling. The air conditioner has to work hard to cool the open or semi closed places.

Working of different parts of the air conditioner

The basic job of an air conditioner is to cool the home and through hot air out of the room. The cool air flows into the room after passing through number of cool pipes, these pipes are called evaporator coil. These coils are in turn filled with refrigerant. The refrigerant changed from liquid to gas when it gets heat from the air. This refrigerant   again becomes liquid in the condenser, which is out of the room.  A compressor is used to move the refrigerant from one coil to another coil and then changes the temperature, so that refrigerant is changed into gas and then back to liquid. The cooling effect will be the three times the energy consumed by the motor to run the system. This more cooling comes from the fact the refrigerant is changed from liquid to gas and then again into liquid.


Generally, ton is used to define the cooling power of air conditioner. A ton is considered as giving 12000 BTU British thermal unit, hour of cooling. The window air conditioners are generally less than one ton, the central air conditioner may range from 2 to 5 tons. 



Every system AC on Rent in Dwarka has filters in upstream of the evaporator coil. The job of the filters is to remove the dust particles from air to run system smoothly.  The blocking of particles in the course of time reduces the efficiency of the filters and system. The cleaning of filters and changing them, if necessary, is must to ensure the constant performance from air conditioner. The environment, in which air conditioner operates and air, it has to filter, determines the time needed to repair or clean filters.

Duck leakage can undermine the cooling effect of the air conditioning system. The leakage in duct can reduce efficiency of a system by up to 40 %. The duct has to be insulted, if it is outside the cooling space .if home owner is not able to seal the leakage duct, then professional help should be taken.


An air conditioner must ventilate the air inside the room. If it fails to do this vital function, the contaminate air will pose health issues to the occupants.  An effective air conditioner must ventilate, dehumidify and provide healthy environment inside the cooling space.


The load of the Window AC on rent in Dwarka air conditioning system can be reduced by properly closing the room of its installation. This ensures that lot of energy is not spent on cooling. The open room or space makes air conditioning work harder by using more energy.

As far as possible, the cleaning of filters, compressor and fins can be done by homeowners easily. The charging of refrigerant and compressor work should be left to the professionals who are trained to do the job.  Normally, just before the start of the system, the complete system should be cleaned by professionals.
