The Three Things People Call "Aircon Service" (They're Not the Same)
"I need my aircon serviced" can mean three different jobs depending on what's actually wrong:
- Standard servicing / chemical wash — routine cleaning to remove bacteria, mould, and odour from the coil and filter, restoring cooling performance. This is what most people mean by "servicing."
- Deep Clean Drain Piping — a targeted fix for an aircon that's actively leaking or dripping water, caused by a blocked drain line. From RM20 per unit when booked with a service visit. Not a substitute for regular servicing.
- Klima Maintenance Plan — an ongoing contract with scheduled preventive visits, asset assessment, and proactive spare part management, aimed at catching problems before they cause a breakdown.
Booking the wrong one is the most common reason people feel like "servicing didn't fix it" — a chemical wash won't stop an active leak, and a one-time drain fix won't restore cooling power if the coil itself is dirty.
What's Included in Standard Servicing
Ban Leng's standard service is a deep cleaning and chemical wash that:
- Removes bacteria, mould, and accumulated grime from the coil and filter
- Clears odour caused by microbial buildup
- Restores airflow and cooling efficiency that gets lost as the coil clogs up over time
Pricing depends on the number of units, unit type, and condition, so Ban Leng quotes this over WhatsApp rather than a flat published rate — send your unit count and HP and you'll get a number back same day.
What Aircon Servicing Typically Costs (2026 Market Rates)
Since exact pricing depends on your setup, here's a realistic range to go in with, based on typical Malaysia market rates for wall-mounted units up to 2.5HP — cassette/ceiling units generally run about double:
| Service Type | Typical Price (per unit) | What's Different |
|---|---|---|
| General cleaning (no chemicals) | RM80 – 120 | Filter wash, fan/blower wipe, outdoor unit check — no coil cleaning |
| Chemical wash | RM115 – 150 | Adds chemical cleaning of the indoor coil, plus a gas top-up if needed |
| Full overhaul | RM180 – 220 | For units left unused over a year — full dismantle, chemical clean, and drain flush |
Prices per unit typically drop when you book multiple units at once (e.g. servicing all 3 units in a home together costs less per unit than booking one at a time). A diagnostic/checkup visit for a specific problem (noisy, smelly, not cooling) is commonly priced separately, though many providers waive it if a repair goes ahead the same visit.
These are general Malaysia benchmarks, not Ban Leng's fixed rate — WhatsApp your unit count and condition for your exact Penang quote.
Is It a Leak, Not a Dirty Coil? You Might Just Need the Drain Fix
If your aircon is cooling fine but dripping or leaking water, that's usually a blocked drain pipe, not a dirty coil — and it doesn't need a full service to fix. Ban Leng's Deep Clean Drain Piping add-on handles it in one visit:
- Purge the drain line — flush with pressurised water to clear debris, dirt, and standing water
- Apply Kalt K-dry Booster — dissolves the jelly-like organic sludge and algae that caused the blockage in the first place
This starts from RM20 per unit when bundled with a servicing visit, with no separate appointment needed.
Ban Leng is explicit that this is a targeted fix for the current leak, not a long-term preventive measure — if leaks keep recurring, that's a sign to move to a regular maintenance plan instead of repeating the one-time fix every few months. For the full breakdown of why aircon units leak in the first place, see our Aircon Leaking Water guide.
For Ongoing Prevention: The Klima Maintenance Plan
If you're servicing the same unit reactively every few months, a maintenance contract usually works out better than repeated one-off visits. Ban Leng's Klima Maintenance Plan includes:
- Asset assessment and environmental analysis for your specific setup
- Routine monthly servicing built into the contract
- Data-driven maintenance decisions rather than guesswork
- Proactive spare part management, so replacement parts are sourced before something fails
- Priority recovery support if a unit does break down
This is quoted per property/unit count after an initial assessment — WhatsApp Ban Leng to arrange a walkthrough.
How Often Should You Actually Service Your Aircon?
- General servicing (filter/coil clean): every 3–4 months — Malaysia's heat and humidity mean units here work harder than the manufacturer's baseline assumptions, so the standard "once or twice a year" advice from cooler climates doesn't really apply
- Full chemical wash: once a year — clears deeper coil contamination that a basic clean doesn't reach
- Full overhaul: if a unit has sat unused for over a year — a heavier one-off clean that also gives the technician a chance to flush the drainage line while it's dismantled
- Drain line check: as soon as you notice dripping — don't wait for the next scheduled service if water is actively leaking; the sludge buildup gets worse the longer it sits
Units serviced on this rhythm typically use less electricity, break down less often, and last longer before needing compressor-level repairs.
FAQ
It depends on unit count, HP, and condition, so Ban Leng quotes this over WhatsApp rather than publishing one flat rate. As a general Malaysia market guide, a basic clean typically runs RM80–120 per unit and a chemical wash RM115–150 per unit, with per-unit cost dropping when you book multiple units together. The Deep Clean Drain Piping add-on (for active leaks specifically) starts from RM20 per unit when booked with a service.
Servicing is a chemical wash that cleans the coil and filter to restore cooling and remove odour. The drain piping fix specifically clears a blocked drain line causing a water leak — it's an add-on, not a replacement for regular servicing.
General servicing every 3–4 months, with a full chemical wash once a year for deeper coil contamination. If a unit has sat unused for over a year, a full overhaul is worth considering instead.
A one-time drain fix is designed for the current leak, not long-term prevention. If leaks keep recurring, switch to the Klima Maintenance Plan so the root cause gets addressed on a preventive schedule instead of being fixed reactively each time.
