Established since 1989, Wisma's core business has been in the air conditioning field together with its corollary electrical engineering aspects.

The philosophy of keeping abreast with developments of our core business continues today so that we can offer the best available solutions in air-conditioning needs to our customers.

The same can also be said to our servicing department as new methods, tools and chemicals became a necessity for providing top grade servicing and maintaining of air-conditioning systems. To us, failure to provide a satisfactory level of service is not an acceptable option.
