Like any other inventions, air conditioners have some history and during the 18th century it was reported that Khalif of Baghdad in order to get a relief from the unbearable heat, doubled the walls of his rooms so that he could keep ice cubes between those walls so that the summer would become bearable and the method proved to be a success and during 1902, by joining together the ammonia coil and the air compressor, the first air conditioner was built and today the air conditioners are available in different sizes suiting to the needs of members living in houses; people working in offices; workers performing activities in industrial houses and many more. The air conditioners of present generation apart from cooling a single room are capable of cooling the entire building and for this purpose huge air conditioning units are installed. However, for some people, purchasing an air conditioner may not be possible due to financial difficulties and during those occasions, Cash advance available from the financial institutions and reputed bankers are much helpful. When it comes to air conditioners, people who are willing to install such units in their homes should have sufficient knowledge about the various facilities available through such units. The size and capacity of the air conditioners differ according to the rooms in which they are going to be installed. In order to have the air conditioners in the rooms, the rooms should be fully sealed and external air should not be allowed inside the rooms. The air conditioner functions in such a manner that it sucks the air available inside the rooms and sends the air outside the rooms by means of outlets provided to the air conditioner thereby allowing cooled fresh air inside the room and through the controlling devices the temperature can be either reduced or increased according to the desired levels. The Cash advances loans available from the financial dealers are very much helpful during the course of purchasing one air conditioner and the amount can be repaid in easy installments and the loans can be availed by adopting simple procedures.
