Abstract: It is provided a system for cleaning a blower and an air inlet filter of an air condition unit using condensed water. The system includes a reservoir for condensed water, a first sub-system for facilitating flowing pressurized liquid in a duct having spraying outlets, and a second sub-system for removal of sprayed liquid out of the air condition unit. The cleaning liquid includes condensed water and a cleaning additive. The air inlet filter may rotate on a pair of pulleys, and the filter is exposed to the sprayed liquid by rotating a pulley while spraying. The system includes barriers disposable in a separating position between the cleaned parts and other objects. The system also includes a manipulating handle or an electric motor, for placing the barrier. Electrical circuitry may automatically initiate cleaning the parts on turning-off the air condition unit. The system include a chamber for a cleaning additive and a mixing mechanism for mixing the cleaning additive with the condensed water.
