An air conditioning specialist and original co-director of HydroKleen operated his own air conditioning company in Darwin for 25 years. He saw a need for speeding up the process of cleaning split system air conditioners, especially given that nearly every household has 1 or more air conditioners of some sort, whether for cold and/or hot air. There was no industry standard for the cleaning of air conditioners. The first prototype proved that he could clean up to 12 units a day compared to 2 or 3 using the traditional ‘strip and clean’ method. The strip and clean method was not time efficient, nor was it cost effective.
