Aircond System Overhaul Kuala Lumpur

The most thorough non-replacement service there is — full dismantle, deep coil wash, fan bearing and capacitor replacement, drainage rebuild, electrical re-tightening and gas restore. The right call when the compressor is healthy but the unit is noisy, weak, or leaking. Cheaper than a new unit, for residential and commercial across all 24 KL districts.

What It Is

Aircond overhaul explained

Direct Answer

An aircond overhaul is the most thorough non-replacement service we offer. We fully dismantle the unit, deep chemical wash the coil, replace the fan bearing and blower motor capacitor, rebuild the drainage system, re-tighten the electrical terminals, check the swing motor and sensors, and restore gas pressure. It's the right call when the compressor is still healthy but airflow and cooling have badly degraded, the unit is noisy or vibrating, or several small faults have stacked up. Done in about 3 hours per unit — and far cheaper than buying new.

What's Included

What an aircond overhaul covers

Every overhaul we do in Kuala Lumpur follows the same six-stage scope, residential or commercial. Photo evidence at each stage, sent on WhatsApp.

1. Full dismantle

Indoor casing, filter, blower fan, swing flap, PCB cover, drain pan and motor assembly all removed. Every component inspected before work begins.

2. Deep chemical coil wash

Evaporator coil and blower deep-soaked in biodegradable solvent, then pressure-flushed until runoff runs clear. Restores airflow the same way a standalone chemical wash does.

3. Fan bearing & capacitor

Worn blower fan bearing replaced to kill the rattle and vibration; blower motor capacitor swapped so the fan spins back up to full speed instead of stalling or running weak.

4. Drainage system rebuild

Drain pan, channel and full drain line cleared and rebuilt — not just flushed. Stops the chronic dripping and clogging that recur on units that only ever get a quick service.

5. Electrical & controls

Terminal block and connections re-tightened to stop heat-soaked loose contacts; swing motor and temperature sensors tested and recalibrated so the unit reads and cycles correctly.

6. Gas restore & final test

Refrigerant lines leak-checked and gas pressure restored to OEM spec. Unit reassembled, run for 15 minutes, and outlet temperature measured pre and post on the job sheet.

When You Need It

Six signs your aircond needs an overhaul, not just a wash

If two or more of these apply, a chemical wash or general service alone won't fix it — the unit needs parts, drainage and electrical work too.

1

Loud rattling or vibration from the indoor unit

A worn fan bearing is grinding. No amount of cleaning fixes this — the bearing has to be replaced, which is part of the overhaul, not a wash.

2

Cooling stayed weak even after a chemical wash

If you washed the coil and the room is still warm, the bottleneck has moved past the coil — usually a weak blower (capacitor) or low gas. An overhaul addresses all of it at once.

3

Drainage keeps clogging and dripping

If the unit drips again within weeks of a flush, the drain pan and line need rebuilding, not flushing. Overhaul rebuilds the whole drainage path.

4

Several small faults have stacked up

Weak airflow, a stuck swing flap, a faint burning smell, slow start-up — when three or four niggles pile on one unit, an overhaul fixes them in one 3-hour visit instead of repeat call-outs.

5

Compressor is fine but the unit feels "tired"

The outdoor compressor still kicks in and holds, but the unit no longer cools like it used to. That's the ideal overhaul case — healthy compressor, everything else restored.

6

You're weighing repair against a brand-new unit

Before you spend on a replacement, let us inspect it. If the compressor is healthy, an overhaul restores near-original performance for a fraction of the price of a new aircond plus install.

Residential & Commercial

Overhauls for homes and commercial premises

Whether it's a 6-year-old bedroom unit in Cheras or a hardworking cassette in a Bangsar cafe, the scope is the same — only the unit count and run-hours change.

Residential

Apartments, condos and landed homes with units 5–10 years old that still have a good compressor but have gone noisy, weak or drippy. An overhaul buys years more life and saves the cost of a full replacement plus re-install.

Commercial

F&B outlets, retail, clinics and offices running long hours where downtime costs money. Overhauling a fleet of healthy-compressor units is far cheaper than replacing them and keeps the floor cool through peak trade.

Frequently Asked

Aircond overhaul FAQ

What is an aircond overhaul?

The most thorough non-replacement service we offer. We fully dismantle the unit, deep chemical wash the coil, replace the fan bearing and blower motor capacitor, rebuild the drainage system, re-tighten electrical terminals, check the swing motor and sensors, and restore gas pressure. It's the right call when the compressor is still healthy but airflow and cooling have badly degraded — restoring near-original performance for far less than a new unit. Takes about 3 hours per unit.

Overhaul vs chemical wash vs replacement — which do I need?

A chemical wash only cleans the coil — about 90 minutes — and fixes weak cooling caused by a dirty coil. A general service only does the filter and blower. An overhaul does all of that plus replaces worn parts (fan bearing, capacitor), rebuilds drainage, and re-tightens electrical — a full restoration when several faults have stacked up. Replacement is only worth it when the compressor is dead or the unit is too old; if the compressor is healthy, an overhaul costs less and restores near-original performance.

How long does an aircond overhaul take in KL?

About 3 hours per unit, because an overhaul covers cleaning, parts replacement, drainage rebuild and electrical work in one visit. Same-day dispatch across all 24 KL districts if the job is confirmed before 4 PM; otherwise next-day. Multi-unit jobs are staffed with a small team so they finish in one trip.

Is an overhaul worth it or should I just buy a new aircond?

If the compressor is still healthy, an overhaul is almost always cheaper than a new unit and restores near-original cooling, airflow and quiet running. We're honest about it: if your inspection shows a dead compressor or a unit too old to justify the work, we'll tell you to replace it instead of selling you an overhaul that won't pay off. Overhauls come with a 3-month labour warranty.
