# Standard Cleaning vs Chemical Wash | Aircond Ipoh > Standard cleaning (RM85) wipes filters; a chemical wash (from RM160) deep-cleans the coil. See which aircond service you actually need.

Some pay for a deep wash when a quick clean would do; others pay for a wipe-down when their unit badly needs dismantling. The dividing line is simple once you see it: what actually happens inside the machine. Look at all aircond servicing options [/ →](/) and the choice comes down to standard cleaning versus a chemical wash. Here is exactly how they differ. ## Standard Cleaning: The Surface Tune-Up A standard cleaning handles the parts you can see and reach without opening the unit. At RM85, it covers the filter, the cover panels and an external wipe of the blower wheel, and takes about 20 to 30 minutes per unit. It does a useful job. Surface dust and pet dander build up quickly, and regular wiping keeps airflow clear and reduces common indoor allergens. Think of it as a quick tune-up between deep cleans. What it cannot do is reach the coil or the drainage tray. In Ipoh’s climate, that limit matters. With Kinta Valley humidity sitting near 84 percent year-round, moisture inside the unit creates a sticky bio-slime, often called aircond jelly, deep in the drain pipe. Once that slime forms, no surface wash will stop a water leak. > **Quick check** > > If your unit still cools the room to your set temperature in reasonable time, with no smell and no water dripping, a standard clean is likely all you need right now. ## Chemical Wash: The Full Dismantle A chemical wash is a full-dismantle deep clean. The technician removes the blower wheel, flushes the evaporator coil with an alkaline solution, clears the drainage tray, and dissolves hidden mould before reassembling the unit. For wall units, the price runs RM160 to RM210 depending on size. Ceiling and cassette units take longer to dismantle, so they cost RM280 to RM400. ![Comparison chart showing standard cleaning versus chemical wash inclusions](/images/content/comparison-chart-of-standard-cleaning-vs-chemical-.webp) Every deep wash includes a free gas top-up of up to 10kg, covering R22, R32 and R410A. That matters, because standalone R32 or R410A refills often cost RM130 to RM200 on their own. The included top-up with our aircond chemical wash service [/aircond-chemical-wash/ →](/aircond-chemical-wash/) is real value. Worth remembering: gas does not evaporate, so if your system is constantly low, you have a leak that needs fixing. The coil is where the real work happens. We use a non-corrosive, alkaline-based cleaner to strip dirt without harming the copper fins. Cheap acidic cleaners eat into the metal and cause permanent damage. Once dust, mould and bio-slime coat the coil, cooling collapses, and no amount of filter washing brings it back. | Service | What Is Cleaned | Includes Gas Top-Up | Price | | --- | --- | --- | --- | | Standard cleaning | Filter, cover, blower wipe | No | RM85 | | Chemical wash (wall unit) | Full dismantle, coil, drainage | Yes, up to 10kg | RM160 to RM210 | | Chemical wash (cassette/ceiling) | Full dismantle, coil, drainage | Yes, up to 10kg | RM280 to RM400 | ## When Each One Is the Right Call Match the service to how your unit is performing today and how long it has been since the last deep wash. **Choose a standard clean if:** - Your unit was chemically washed in the last 12 months - It still cools well with no musty smell - You are doing quarterly maintenance between deep washes - The filter and cover look dirty, but the unit is otherwise fine **Choose a chemical wash if:** - It has been more than 12 months, or you cannot remember the last wash - Cooling is noticeably weaker than it used to be - A musty or mouldy smell appears when the unit runs - Water is dripping from the indoor unit, a sure sign of bio-slime - Dust or dark patches are visible on the vents - The unit keeps tripping or runs constantly without reaching the set temperature Ignoring a needed chemical wash is expensive in itself. A clogged unit can use 15 to 25 percent more electricity, and under the current TNB RP4 tariff a struggling 1.5HP non-inverter unit can cost over RM170 a month to run. One way to picture it: a standard clean is like vacuuming the visible floor, while a chemical wash is moving the furniture and scrubbing the tiles underneath. You need both, just at different times.

Guide FAQ ## Common Questions Is a standard cleaning enough for my aircond? A standard cleaning is enough if your unit still cools well and was chemically washed within the last 12 months. If cooling has weakened or the unit has a musty smell, a chemical wash is the right choice. How much more does a chemical wash cost? Standard cleaning is RM85 and covers only the filter, cover and blower wipe-down. A chemical wash starts at RM160 for wall units and includes a free gas top-up of up to 10kg, so the price jump brings a real jump in what gets done. Does standard cleaning include a gas top-up? No. Standard cleaning does not include a gas top-up or any work on the coil or drainage. Only a chemical wash or a repair job includes the free gas top-up. ## Related Guides ### How Often Should You Service Your Aircond?
