If you're comparing aircon installation cost in KL for 2026, here's the number that matters: labour starts at RM250 for a 1–1.5HP unit. Everything past that — 2HP, 3HP, extra piping, awkward wall positions — moves the price up in predictable steps. This guide breaks down exactly what you pay, what's included, and what our technicians actually do on installation day.
How Much Does Aircon Installation Cost in KL in 2026?
Labour-only installation for a standard split unit ranges from RM250 to RM400, depending on the horsepower (HP) of the unit. Here's the exact breakdown:
| Unit Size | Labour Cost | Included |
|---|---|---|
| 1–1.5HP | RM250 | 6ft copper pipe, 10ft PVC pipe, outdoor bracket |
| 2HP | RM300 | 6ft copper pipe, 10ft PVC pipe, outdoor bracket |
| 3HP | RM400 | 6ft copper pipe, 10ft PVC pipe, outdoor bracket |
These are Cheras and Klang Valley rates. Ampang, Kajang, Petaling Jaya, Subang Jaya, and Shah Alam all fall under the same pricing — see the full pricing page for every service we quote.
What's Included in the Labour Price?
The labour price covers mounting, standard piping, and a working system at the end — not the unit itself. You buy the aircon unit (Daikin, Mitsubishi, Panasonic, Midea, whichever brand you've picked) from a retailer, and our technician handles everything from there: drilling, bracket fitting, copper pipe brazing, wiring, and a final gas pressure check.
Anything beyond the standard 6ft copper and 10ft PVC allowance is charged as an add-on. Most single-storey homes with the outdoor unit placed close to the indoor unit fall within that allowance. Double-storey homes or units placed far from the compressor usually don't.
Step-by-Step: What Our Technician Does on Installation Day
A new unit installation in Cheras or anywhere in the Klang Valley follows the same sequence every time:
- Site check — confirm indoor wall location and outdoor compressor placement, check for a clear path to run copper piping.
- Mounting plate fitting — the indoor unit's back plate gets leveled and screwed to the wall.
- Drilling — a hole is drilled through the wall for the copper pipe, drain hose, and wiring to pass through to the outdoor unit.
- Copper piping and brazing — copper pipes are cut to length, flared, and brazed to prevent leaks. This is the step that determines whether your unit holds gas long-term.
- Outdoor bracket and unit mounting — the compressor gets bolted onto a wall bracket or placed on a stand, away from direct rain where possible.
- PVC drain pipe routing — condensate drainage is run with a slight downward slope so water doesn't pool or leak back into the house.
- Vacuum and pressure test — the line is vacuumed to remove air and moisture, then pressure-tested before the factory-charged gas is released into the system.
- Power-on and cooling test — the unit runs for 15–20 minutes while the technician checks temperature output and listens for abnormal noise.
Skipping the vacuum step is one of the most common shortcuts bad installers take — it leads to moisture inside the system, which shows up months later as reduced cooling or a compressor fault.
What Makes Installation Cost More?
Distance and access are the two biggest cost drivers. If the outdoor unit sits more than 6ft of pipe run from the indoor unit — common in landed houses with the compressor on the ground floor and the bedroom unit upstairs — extra copper pipe is charged per foot on top of the base RM250–RM400.
High-wall installations (units mounted above 10ft, or outdoor compressors on a roof ledge) also cost more due to the extra time and safety equipment needed. Multi-split systems, where one outdoor compressor runs two or three indoor units, are quoted per system rather than per indoor unit, since the outdoor unit and main piping only get installed once.
Reinstallation: Moving an Existing Aircon
Reinstalling a unit you already own — say, after renovation or moving house — uses the same RM250–RM400 labour scale. The difference is that opening the system to move it usually lets some refrigerant escape, so a gas top-up (RM150–RM250) is often needed afterward to bring the unit back to full cooling capacity. Ask your technician to quote both together upfront rather than being surprised by a second bill.
Frequently Asked Questions
How much does aircon installation cost in KL in 2026? Labour-only installation costs RM250 for 1–1.5HP units, RM300 for 2HP units, and RM400 for 3HP units. This includes 6ft of copper pipe, 10ft of PVC drain pipe, and the outdoor unit bracket.
Does the installation price include the aircon unit itself? No, the prices above are labour only. You buy the unit separately from a retailer or supplier, and our technician handles the mounting, piping, wiring, and gas charge check.
How long does aircon installation take in KL? A standard split-unit installation takes 2 to 3 hours for one indoor and outdoor unit pair. Multi-split systems or units on high walls take longer.
Is reinstalling an old aircon cheaper than a new installation? Reinstallation usually costs the same RM250–RM400 labour rate, but often needs a gas top-up afterward since the system is opened and recharged. That's billed separately at RM150–RM250 depending on how much gas is needed.
