Aircon & Electrical Wiring Installation in Kuala Lumpur

Aircon and electrical wiring installation covers a wide range of work: mounting and piping new split or multi-split units, running dedicated wiring and circuit breakers for aircon load, rewiring old or renovated units, upgrading consumer units (fuse boxes), and installing points for kitchens, lighting, or built-in appliances. In Kuala Lumpur's older flats and pre-war shophouses this often means replacing undersized or aging wiring before a new unit can be safely connected. In newer condos, the work tends to be lighter: running piping through ceiling voids, connecting to existing points, and disposing of old units.

We list 28 businesses in Kuala Lumpur that handle this category, ranging from small two- or three-man outfits to larger firms that also do renovation electrical work. Before hiring, check that the installer is comfortable pulling a Suruhanjaya Tenaga (ST) wireman's license or working under one, since unlicensed wiring work is both a safety risk and technically illegal for anything beyond basic plug-and-play jobs. Ask whether the quote includes piping, insulation, drainage routing, and disposal of the old unit, as these are common places where "cheap" quotes balloon later.
