Established since 1989, Wisma’s core business has been in the air conditioning field together with its corollary electrical engineering aspects.
Air conditioning technology and equipment have evolved through this period, from the simple window units to the single-split, multi-split and then to the inverter series for household needs. In the larger context of office and industrial application, we have seen the evolution from the huge standalone ducted units to the versatile VRV/ VRF systems.
Refrigerant gases were primarily of the DuPont Freon series (ozone-depleting CFCs) and have since been replaced by other ozone-friendly refrigerants.
Wisma stayed on-course with the core business to acquire new skills and upgrade itself as air-conditioning technology evolved and developed. That persistence was to ensure that customers can be served in the best possible way.
The philosophy of keeping abreast with developments in 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 of our servicing department as new methods, tools and chemicals became a necessity for providing top-grade servicing and maintenance of air conditioning systems. To us, failure to provide a satisfactory level of service is not an acceptable option.Meet Our Team
