🇲🇾 Aircond Membeku · 🇨🇳 冷气结冰
Aircond ice formation is caused by low refrigerant gas or severely blocked evaporator coils. KL Renovator diagnoses the root cause and performs the correct service — gas top-up or chemical overhaul.

Direct answers
Ice on the indoor coil means the surface is below freezing — either gas is low or almost no air is moving across the fins. Both starve the compressor of superheat. Switch to Fan, never scrape the ice, then book a diagnosis. Running Cool on a frozen coil can slug liquid back to the compressor.
Thaw on Fan for one to three hours, rinse the filter, then stop. The next step is a gauge reading on a fully clear coil. KL Renovator either leak-checks and tops up or washes the coil. WhatsApp a photo of the iced pipe before you thaw if you can — it helps us bring the right gas.
Thaw advice is free. After thaw, gas is RM 2.50 / PSI or RM 3.00 / PSI per PSI actually added. Chemical wash from RM 120. Wall-mounted overhaul from RM 420 when the coil is packed solid. Diagnostic RM 88 waived with the repair. Same-day slots run across KL and Selangor once the part is on the van.
No. Ice means liquid refrigerant is not finishing its job in the evaporator. That liquid can wreck the compressor, which costs RM 800 – 2,000. Fan-thaw, then call. A few hours without Cool is cheaper than a compressor. The signed job card lists the part and the price so nothing is left verbal.
Step-by-step
Fan-thaw first, never chip ice, then pressure and airflow checks — the sequence that protects the compressor.
Do not chip ice. Fan-only for one to three hours melts the coil without thermal shock. Towels under the fascia catch the water.
A blocked filter is the cheapest freeze cause. If the mesh is torn, replace it before restarting Cool.
Gauges on a frozen coil lie. After thaw, low pressure means a leak-checked top-up (RM 2.50 / PSI / RM 3.00 / PSI). Normal pressure plus weak airflow means the coil or blower is blocked.
Blocked coil: chemical wash from RM 120, or wall-mounted overhaul from RM 420 if ice was thick. Leak: repair then charge. Never charge a still-icy system.
We restart Cool and watch the suction line for twenty minutes. Frost returning immediately means the root cause is still open.
Definitions
Short, plain-language definitions of the terms used above — written by the technicians who do the work, not copied from a manufacturer brochure.
The evaporator is the finned coil inside the indoor unit where cold refrigerant absorbs heat and moisture from the room air. Because it is permanently wet during operation, it is where mould, bacteria and dust bind together into the grey film that causes the sour smell and the drop in airflow. Filters catch the coarse dust; the coil holds the rest.
If the airflow feels weak right after a filter wash, the coil — not the filter — is the blockage, and that needs a chemical wash.
Refrigerant is the working fluid that carries heat out of your room. Malaysian homes run three types: R22 in older non-inverter units, R410A in mid-generation inverters and R32 in most units sold today. They operate at different pressures and use different compressor oils, so they can never be mixed or substituted — doing so damages the compressor and voids any warranty.
Photograph the outdoor unit nameplate before you book — it tells the technician the gas type and charge weight, and stops a wrong-gas quote.
PSI is pounds per square inch, the pressure reading the technician works to when charging. Each refrigerant has its own running-pressure window — roughly 60–70 PSI for R22, 120–140 for R410A and 130–150 for R32 on the suction side at Malaysian ambient temperatures. Charging by PSI is why gas top-up is billed per PSI rather than as a flat fee.
Ask for the before-and-after pressure readings on the invoice; that single line makes an over-charge or an invented top-up obvious.
Side-by-side comparison
Refrigerant is not consumed by running the unit, so a top-up is only ever a temporary answer.
| What to compare | Top-up only | Find and repair the leak |
|---|---|---|
| How long cooling lasts | Weeks to months, depending on leak size | Years, if the joint is properly remade |
| Time on site | Under an hour | Longer — pressure test, then repair and recharge |
| Published price | RM 3.00 / PSI (R32) | RM 120 / leak |
| Risk if ignored | Compressor runs hot and under-lubricated | Removes the cause |
In short: One top-up on an old unit is reasonable. A second within twelve months means you are paying rent on a leak you have not fixed.
Important
A freezing aircond will eventually stop cooling completely — and running it in this condition damages the compressor. Switch off and get it inspected before the damage worsens.
Aircond yang membeku akhirnya akan berhenti menyejuk sepenuhnya — dan menggunakannya dalam keadaan ini merosakkan pekali. Matikan dan dapatkan pemeriksaan sebelum kerosakan bertambah teruk.
结冰的冷气最终会完全停止制冷——在此状态下运行会损坏压缩机。请关机并检查，以防损坏加剧。

The Fix
🇬🇧 English
Switch off the aircond immediately and let it defrost for 2 hours with the fan running on a separate setting if available. Do not chip or scrape the ice. Once defrosted, KL Renovator will perform a gas pressure check — if low, the leak is found and sealed before recharging. If the coil is blocked, a chemical overhaul clears it completely. Both causes are fixed in one visit.
🇲🇾 Bahasa Malaysia
Matikan aircond segera dan biarkan ia cair beku selama 2 jam. Jangan kikis ais. Setelah cair beku, KL Renovator akan memeriksa tekanan gas — jika rendah, kebocoran ditemui dan ditutup sebelum mengecas semula. Jika gegelung tersumbat, overhaul kimia membersihkannya sepenuhnya.
🇨🇳 中文
立即关闭冷气，让其自然化冻2小时（如果风扇可单独开启则保持运转）。不要刮除冰块。化冻后，KL Renovator进行气压检查——如不足则先找漏并修复再充气。若盘管堵塞则进行化学大修彻底清洁。两种原因均可一次上门解决。

FAQs · Soalan Lazim · 常见问答
Ice on the indoor unit (evaporator coil or copper pipes) means either the refrigerant gas is low, the coil is severely blocked, or the fan is not moving enough air. Switch off the unit and WhatsApp KL Renovator — +60182983573. Most cases fixed same-day.
Step 1: Switch off the aircond from the remote or MCB. Step 2: If your unit has a fan-only mode, run it to help defrost. Step 3: Wait 1–2 hours until all ice melts. Step 4: WhatsApp KL Renovator at +60182983573 for a gas check + chemical overhaul.
Gas top-up from RM 2.50/PSI (R22), RM 3.00/PSI (R410A), RM 3.00/PSI (R32). Chemical overhaul (if coil blocked) from RM 420. Often both are needed — KL Renovator checks and quotes before work. Diagnostic RM 88 (waived with repair).
Ice on the coil means liquid refrigerant isn't fully evaporating before returning to the compressor, which can damage or destroy it.
Usually 1-3 hours in "Fan" mode. Don't use a hairdryer or hot water directly on the coil, as sudden temperature change can crack components.
Not if the root cause (low gas leak or coil blockage) is properly identified and fixed rather than just clearing the ice.
No — freezing is caused by gas level and airflow, which applies equally across all brands.
🇲🇾 Bahasa Malaysia
Ais pada unit dalam bermakna gas penyejuk rendah, gegelung tersumbat teruk, atau kipas tidak cukup mengalirkan udara. Matikan unit dan WhatsApp KL Renovator — +60182983573.
Langkah 1: Matikan aircond. Langkah 2: Tunggu 1–2 jam sehingga semua ais cair. Langkah 3: WhatsApp KL Renovator +60182983573 untuk semak gas + overhaul kimia.
Ais pada gegelung bermakna penyejuk cecair tidak menyejat sepenuhnya sebelum kembali ke pekali.
Biasanya 1-3 jam dalam mod "Fan". Jangan gunakan pengering rambut atau air panas terus pada gegelung.
🇨🇳 中文
室内机（蒸发器盘管或铜管）结冰表示制冷剂不足、盘管严重堵塞或风扇气流量不足。关机并WhatsApp KL Renovator——+60182983573。大多数情况当天可修复。
第1步：关闭冷气。第2步：等待1-2小时直到所有冰融化。第3步：WhatsApp KL Renovator +60182983573进行气压检查+化学大修。
盘管结冰意味着液态冷媒未能在返回压缩机前完全蒸发，可能造成损坏。
通常以"送风"模式需1-3小时。切勿用吹风机或热水直接冲盘管。
