Sim Air-Conditioning Engineering was founded in 1992 as a sole-proprietorship by the Director Sim Siang Eam after he had acquired adequate knowledge and competent Skill in the trade by experience. The business started with a humble beginning as labour sub-contractors for installation and service of air-conditioning ventilation systems and air-ducts. In 1995 it expanded the scope of activities by engaging in fabrication of air-ducts. A factory with a production area of 10,000sq ft was set up in a rented premises No.266-H, MK.12, Jalan Baru Batu Maung, 11960 Bayan Lepas, Penang to carry out the fabrication activities. In the early days, the fabrication process was rather labour intensive. And over the years, the designing and fabrication process was progressively machinized and automated by deployment of more and more advanced equipment and machinery. The machinization and automation programs not only have mitigated the labour shortage problems, but increased the throughput capacity of the factory as well as improving the quality of the products, particulary in term of the degree of engineering precision.
