What residential electrical work covers
Residential electricians handle everything inside the walls of a home: wiring for new builds and renovations, consumer unit (DB box) upgrades, socket and switch installation, lighting circuits, ceiling fan and aircon wiring, earthing and trip-switch issues, and troubleshooting when a circuit keeps tripping or a section of the house loses power. In Petaling Jaya this also includes a lot of rewiring work on older landed properties in areas like SS2, Kelana Jaya, and Bandar Utama, where wiring installed decades ago often needs upgrading to handle modern loads from aircon units, induction hobs, and EV chargers. Condo and apartment owners tend to call for smaller jobs: swapping out old switches, adding sockets, fixing tripping DBs, or wiring smart home fittings.
What to check before you hire
Ask whether the electrician is registered with Suruhanjaya Tenaga (the Energy Commission), since this is a legal requirement for electrical work in Malaysian homes and matters if you ever need to claim insurance after a fault or fire. Get a written quote that separates labour from materials, ask how they handle unexpected issues found once they open up a wall or DB box, and check if they issue any kind of warranty or follow-up visit for the work done. For rewiring jobs, ask how long the property will be without power and whether they can work room by room.
