The company was formed under the name 'ATCO Ref Centre'.


ATCO initially provided only refrigerator repairing services, and in 1986 we started importing spare parts for refrigerators. Two years later, we ventured into the automobile air conditioning services industry by providing automobile air conditioning services and repairs and importing of auto air conditioning spare parts.


In 1992, we expanded the business by importing refrigeration spare parts for retail and wholesale distribution.


ATCO ventured into the domestic and light industrial air conditioner business in 2003, by partnering with the Chinese household air conditioner brand ‘GALANZ’.
