How to make an aircon you already own answer to a phone — the three routes that actually work in a Klang Valley home, the one that quietly fails, and what the installer has to get right.
This is a setup and specification guide, not a price list. Smart-control hardware turns over too quickly for a durable RM range, so the hardware here is described rather than priced — the only figures on this page are for the electrical work, and they come from our power points and sockets guide.

Stripped of the marketing, a smart aircon setup is one thing: something in the room that can issue the same commands your handset issues, and that you can reach from your phone over the internet. Everything else — schedules, geofencing, voice control, dashboards — is built on top of that single capability. Understanding this makes the whole category easy to judge, because the interesting question is never “which app is nicest”, it is how the command gets to the unit, and whether anything tells you it arrived.
Malaysian homes are overwhelmingly on wall-mounted split units, many of them five to fifteen years old and none of them designed with a phone in mind. That is the retrofit problem this guide is about. A brand-new unit bought with Wi-Fi on the box is a different and much simpler situation — if you are still choosing, our aircon types guide and inverter vs non-inverter comparison are the place to start, and it is worth checking whether the model you want ships smart before you buy a hub to compensate.
Every product in this category is one of the following three things, whatever it is called on the box:
| Route | How the command reaches the unit | What it needs | What it cannot do |
|---|---|---|---|
| Built-in Wi-Fi (unit sold smart) | The indoor unit is on your Wi-Fi and talks to the manufacturer’s app directly | Nothing extra — just the home network and the maker’s app | Not available on an older unit; you cannot add it later |
| Manufacturer add-on module | A small board plugs into a service socket inside the indoor unit | A module that exists for your exact model, and an installer opening the unit | Nothing useful, when a module exists — but for many models none does |
| Universal IR hub | The hub fires the same infrared codes your handset fires | A power point, Wi-Fi coverage, and clear line of sight to the unit | Confirm the unit’s real state; survive the handset being used separately |

An infrared hub is a very good imitation of your handset, and it inherits your handset’s single weakness: infrared only travels one way. The hub transmits a command. It has no channel to hear an answer. So the app is not showing you the unit’s state — it is showing you the last command it sent, and quietly assuming that worked.
Nearly every real-world complaint about smart aircon control comes out of that gap. Somebody uses the physical handset, and now the app and the unit disagree. The app says 24°C and cooling; the unit was switched off by hand an hour ago. Or the hub sends “on” to a unit that is already on, and because most handsets transmit a full state package rather than a toggle, the unit obeys perfectly and nothing looks wrong — until a model that does use a toggle turns itself off instead.
None of this makes IR the wrong choice. It makes it a choice you should make knowingly, and it argues for one discipline in the household: once the hub is in, the handset goes in a drawer. If your household will not do that, a manufacturer module is worth chasing harder than the price difference suggests.
Placement is the single largest cause of a setup that works on installation day and fails a fortnight later. An IR hub needs a genuinely clear path to the indoor unit’s receiver window, and it needs solid Wi-Fi at the same spot. Those two requirements often point in different directions.
Every hub needs permanent power, and the best position for infrared is rarely next to an existing socket. This is the part of a smart aircon setup that is genuinely a trade job rather than a shopping decision, and it is the only part of this page that carries a price.
| What the setup needs | Who should do it | Why |
|---|---|---|
| Pair the hub, learn the handset codes, test every mode | You, or the installer during the visit | No mains work involved — it is app configuration |
| A new 13A point at the mounting position | A registered electrician | Live mains work; the new point must come off a circuit with headroom |
| A dedicated circuit for the aircon itself | A registered electrician | An air-conditioner is a heavy load and needs its own cable and protective device |
| Tidying an existing tangle of extension leads | A registered electrician | The tangle is usually the real problem the hub exposed |
Our power points and sockets guide publishes the going rates for that work in the Klang Valley: roughly RM120–RM250 for a socket on surface trunking near the board, RM200–RM400 for a concealed chased-in point, and a dedicated appliance circuit for an air-conditioner from around RM400. Live mains work should be done by a competent person — an electrician registered with Suruhanjaya Tenaga (the Energy Commission) under the Electricity Supply Act 1990 — not by whoever is fitting the hub. If the existing wiring looks tired while the point is being added, that is the moment for an electrical wiring safety inspection rather than a separate call-out later.
Most IR hubs carry a temperature and humidity sensor, and most people assume it reports the room. It reports the hub. A hub sitting on a warm TV cabinet, inside a media unit, or in the path of the aircon’s own airflow will read several degrees away from where you actually sit — and any automation built on that reading inherits the error.
This matters most for the automation people want most: “turn the aircon on when the room passes 28°C.” Built on a badly placed sensor, that rule fires at the wrong time in both directions, and the household concludes that smart control does not work. If a rule like that is the reason you are doing this, put a separate small sensor at seated or bed height away from the airflow, and drive the automation from that instead of from the hub. It is also worth remembering what the reading cannot tell you: a room that will not come down to temperature at all is a servicing problem, not an automation problem — see why an aircon stops cooling and our chemical service guide.
The genuinely useful automations are the dull ones. A bedroom unit that starts twenty minutes before bedtime and steps its setpoint up overnight. A living room that cannot be left running when the last phone leaves the house. A weekday schedule that never runs the study while nobody is in it. These work because they change when the unit runs, which is the variable a household actually controls.
On the energy question, be sceptical of any specific percentage — including one from a vendor. What a schedule saves depends on your unit, your setpoint, your insulation and how disciplined the household was to begin with, and a home that was already switching off diligently has little left to gain. The defensible claim is narrower and still worth having: an aircon that cannot be left running by accident costs less than one that can. How much less depends far more on whether your unit is an inverter and how clean its coil is than on the app — see inverter vs non-inverter, and note that a dirty coil wastes more than any schedule will recover.
One hub per room is the usual answer, because infrared does not go round corners. A three-bedroom home with a living-room unit is therefore typically four hubs, four power points and four sets of learned codes — which is the point at which the electrical work stops being trivial and is worth planning as one visit rather than four call-outs.
Two things save trouble at that scale. First, naming: name by room, not by brand or by hub, and do it during setup, because renaming later breaks every automation that referenced the old name. Second, grouping: a “whole house off” scene is the automation households actually use every day, and it is trivial to build once the naming is sane. For landlords running several units, or a building doing many rooms at once, the coordination question is the same one that governs any batched aircon work — see aircon servicing costs for how batching a visit is priced, and maintenance contracts where the units are commercial.
Because so much of this job is configuration rather than materials, a vague quote is easy to write and hard to argue with afterwards. Insist that the following appear as separate lines:
| Line item | What to check it says |
|---|---|
| Route being used | Built-in Wi-Fi, manufacturer module (for which exact model), or universal IR hub — named, not implied |
| Hardware supply | Whether you or the contractor supplies the hub, and whether it is included in the price |
| Number of hubs and rooms | One per room unless a single hub genuinely sees two units |
| Electrical work | Points, surface or concealed, and whether a dedicated aircon circuit is needed — priced per point |
| Code learning and testing | That every mode is tested: on, off, cool, fan, swing, and each setpoint the household uses |
| Handover | Accounts in your name, not the installer’s, and the schedules demonstrated to you before they leave |
| What is excluded | Wi-Fi coverage improvements, unit repairs and servicing are separate jobs |
The handover line matters more than it looks. A setup registered to the installer’s account is a setup you cannot change, transfer or troubleshoot once they stop answering the phone.
