This category covers the contractors who handle air conditioning for offices, factories, warehouses, retail units, and other non-residential buildings in Shah Alam, including industrial areas like Section 15, 16, 23, and the Bukit Raja / HICOM belt. We've listed 31 businesses that take on this kind of work locally.
What the work involves
Commercial and industrial aircon jobs differ from a home split-unit installation in scale and complexity. Typical scope includes:
- Design and installation of VRV/VRF multi-split systems, ducted units, chillers, and package units for offices, shoplots, and factories
- Cassette and ducted split installs for retail units and F&B outlets
- Scheduled preventive maintenance contracts (monthly or quarterly servicing, chemical wash, filter and coil cleaning)
- Ductwork fabrication, insulation, and repair
- Chiller plant maintenance, cooling tower servicing, and compressor overhaul for factories and larger buildings
- Breakdown callouts, gas top-up, and troubleshooting for systems that have stopped cooling
Larger jobs, especially chiller plants or multi-storey VRF systems, usually need a contractor registered with CIDB and able to handle electrical wiring, refrigerant handling, and sometimes work at height or in confined plant rooms.
What to look for before hiring
- Relevant experience: has the contractor actually done commercial or industrial jobs, not just home units, and can they show past work of similar scale
- Proper licensing and certification: CIDB registration for construction-linked work, and technicians certified to handle refrigerant gas
- Written quotation and scope: brand and capacity of equipment specified, what's included (ductwork, wiring, disposal of old units), and warranty terms on both parts and labour
- Maintenance capability: whether they offer an ongoing service contract, since commercial systems need regular upkeep to avoid costly breakdowns
- Response time for breakdowns: important for factories and offices where downtime costs money
