Deep dismantle clean of the indoor evaporator coil and blower using biodegradable solvent — the only way to restore cooling efficiency on a unit that's been running for 18–24 months. For residential and commercial across all 24 KL districts.
An aircond chemical wash is a deep dismantle clean of the indoor unit's evaporator coil and blower using biodegradable solvent. It removes the layer of compacted dirt, mould, and bacteria that a regular service can't reach — restoring up to 30% cooling efficiency. Recommended every 18–24 months for residential, every 12 months for F&B, and every 6 months for server rooms. Done in roughly 90 minutes per 1.5HP wall-mounted split.
Every chemical wash we do in Kuala Lumpur follows the same six-step scope, residential or commercial. Photo evidence at each stage, sent on WhatsApp.
Mains breaker cut, condenser fan locked, drainage rerouted to a containment tray. Site protection sheet over flooring and walls.
Indoor unit casing, filter, blower fan, swing flap, and PCB cover removed. Drain pan unclipped and inspected for damage.
Coil and blower deep-soaked in evaporator-safe solvent. Loosens 18+ months of compacted dust, bacteria, and biofilm.
Coil and blower flushed with low-pressure water until runoff is clear. Drain channels and pan flushed separately.
Gas pressure checked at the service port; refrigerant lines inspected for leaks before reassembly.
Unit reassembled, powered up, and run for 15 minutes. Outlet temperature measured before and after, recorded on the job sheet.
If any two of these apply to your unit, a general service won't fix it — the coil itself needs to come out.
Mould has reached the visible surface, meaning the evaporator coil behind it is much worse. Filter clean alone won't reach it.
Bacteria and biofilm built up on the cooling coil. The smell hits hardest in the first 30 seconds after the compressor kicks in.
If a general service two months ago helped briefly but the room is warm again, the coil itself is the bottleneck — not the filter.
Drain pan clogged with accumulated biofilm. Chemical wash flushes the pan and drain line at the same time as the coil clean.
Dirty coil makes the compressor work harder for the same cooling. A KL household with two 1.5HP units can see RM30–60 savings per month after a wash.
Even if everything seems fine, KL humidity and urban dust make 18–24 months the practical limit for residential units. F&B should chemical wash every 12 months.
Whether it's an apartment in Mont Kiara or a cafe in Bangsar, the scope is the same — only the schedule and unit count change.
Apartments, condos, and landed homes. Most KL households book chemical wash every 18–24 months — typically two units per visit (master bedroom + living area).
F&B outlets, retail, clinics, offices. Higher run hours and exposure to cooking grease or foot traffic mean chemical wash every 12 months — often staffed with two technicians for parallel coverage.
Send a photo of each aircond, the HP if you know it, and the room. One message is enough — we'll come back with follow-up questions if needed.

Same-day slot if confirmed before 4 PM; otherwise next-day. We send arrival ETA on the morning of the visit.
Six-step scope above. Photo evidence at each stage sent on WhatsApp. Outlet temperature measured pre and post, logged on job sheet.

A deep dismantle clean of the indoor unit's evaporator coil and blower using biodegradable solvent. It removes dirt, mould, and bacteria that a regular service can't reach, and restores up to 30% of cooling efficiency on a dirty unit. Recommended every 18–24 months for residential and every 12 months for F&B and high-traffic commercial.
Around 90 minutes per unit for a standard 1.5HP wall-mounted split — the most common size in KL apartments. Larger 2.5HP+ units take 100–120 minutes. Multi-unit jobs are scheduled with a small team so the work runs in parallel.
Every 18–24 months for residential use, every 12 months for F&B and 24-hour retail, and every 6 months for server/data rooms. KL's humidity and urban dust speed up coil fouling, so units in KLCC, Mont Kiara, and Bangsar usually need it within the shorter end of that range.
A general service cleans the filter, blower, and drainage — about 45 minutes, restoring around 10% efficiency. A chemical wash dismantles the indoor unit and deep-cleans the evaporator coil with solvent — about 90 minutes, restoring up to 30% efficiency. Chemical wash is needed less often but does much more.
