Installation of AC can be quite simple if one is familiar with plumbing and little of electrical work. But most people fear what if something goes wrong. Installation of AC from different manufacturers will have different set of steps that need to be followed, but overall they are more or less the same. Finding a strong support for the indoor unit and placing it is very important. Then the external unit must be kept on leveled surface away from antennas and heating units. We need to adjust the pipes for the follow of water. For maintaining an AC or giving it a long one needs to clean it regularly. First the front coil needs to be cleaned by spraying a cleaning agent. Then one must clean the filter by placing it in water so that the dust particles gets cleared. Affix everything back and start the AC to find a newly serviced AC.
