🇲🇾 Aircond Tidak Sejuk · 🇨🇳 冷气不冷
If your aircond is running but not producing cold air, the most common causes are low refrigerant gas, a dirty evaporator coil, or a faulty capacitor. KL Renovator diagnoses and fixes all aircond cooling problems across KL and Selangor.

Direct answers
Low refrigerant is the cause in more than half of the not-cold calls KL Renovator takes in KL and Selangor. A dirty evaporator coil or a weak capacitor produce the same warm airflow. The usual same-day fix is a leak-checked gas top-up (RM 2.50 / PSI for R22) or a chemical wash from RM 120. Do not keep a warm unit running for weeks — the compressor still draws full power and can seize.
Start with Cool mode, a rinsed filter and a clear outdoor unit. If supply air is still warm, the next checks need gauges: refrigerant pressure, capacitor microfarads, and coil condition. WhatsApp KL Renovator the brand, HP and a photo of the outdoor nameplate. Most not-cold jobs finish in one visit once the leak, wash or capacitor is confirmed.
Diagnostic is RM 88 and is waived if we repair on the same visit. Gas top-up is RM 2.50 / PSI for R22 and RM 3.00 / PSI for R32 or R410A, charged on the actual PSI added. A wall-mounted chemical wash starts from RM 120. Capacitor replacement is RM 150 – 250. Every figure is confirmed before work starts.
Yes for the common causes. KL Renovator vans carry R22, R410A and R32, wash chemicals, and the usual capacitor sizes. Same-day slots run across KL and Selangor. If a hidden copper leak needs brazing we still diagnose on the first visit and book the follow-up with the quote already agreed.
Step-by-step
Step-by-step check KL Renovator uses when an aircond in KL or Selangor runs but blows warm air — from remote settings to gas pressure and coil inspection.
Set the remote to Cool, not Fan or Dry, and 24–26°C. A unit left on Fan will blow room-temperature air even when the compressor is healthy.
A clogged washable filter starves the evaporator of air and makes the supply feel weak and warm. Rinse it, dry it, and refit it before calling a technician.
Leaves, boxes or a closed service-ledge door choke condenser airflow. Give the outdoor unit 30 cm of clear space on the discharge side.
KL Renovator connects a manifold gauge and compares suction and discharge against the nameplate. Low pressure is the most common not-cold finding; we leak-check before any top-up (RM 2.50 / PSI for R22, RM 3.00 / PSI for R410A, RM 3.00 / PSI for R32).
A weak run capacitor can mimic low gas. If the coil is blocked we do a pressure chemical wash from RM 120. You get a confirmed quote before any part is replaced.
Definitions
Short, plain-language definitions of the terms used above — written by the technicians who do the work, not copied from a manufacturer brochure.
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.
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.
The capacitor is a small cylinder in the outdoor unit that gives the compressor and fan motor the starting kick they need. Heat ages it faster than any other part, so it is the most common single failure in Malaysian conditions. Typical symptoms: the outdoor fan hums but will not spin, the unit trips the breaker on start, or cooling works only intermittently.
A capacitor swap is quoted from RM 150 – 250 and takes minutes — always rule it out before anyone quotes you a compressor.
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
Do not ignore an aircond that is not cold. A running but ineffective unit consumes full electricity while delivering no comfort — and low gas pressure damages the compressor over time.
Jangan abaikan aircond yang tidak sejuk. Unit yang berjalan tetapi tidak berkesan menggunakan elektrik penuh tanpa memberikan keselesaan — dan tekanan gas rendah merosakkan pekali dari masa ke masa.
不要忽视不冷的冷气。运转但无效的机组消耗全额电力却毫无舒适感——长期低气压还会损坏压缩机。
Before You Book
🇲🇾 Semak remote ditetapkan pada mod "Cool", bukan "Fan" atau "Dry"
🇲🇾 Semak dan bilas penapis udara boleh basuh — penapis tersumbat sahaja boleh menyebabkan aliran udara lemah dan panas

🇨🇳 检查遥控器是否设为"制冷"模式，而非"送风"或"除湿"模式

The Fix
🇬🇧 English
KL Renovator technicians first run a full system check — measuring discharge pressure, suction pressure, and temperature difference across the coil. If gas is low, the leak is located and repaired before topping up to the correct operating pressure. If the coil is dirty, a chemical wash restores heat exchange. If the capacitor is failing, it is replaced on the spot. You receive a transparent quote before any work starts.
🇲🇾 Bahasa Malaysia
Juruteknik KL Renovator menjalankan pemeriksaan sistem penuh — mengukur tekanan pelepasan, tekanan sedutan dan perbezaan suhu. Jika gas rendah, kebocoran dikesan dan diperbaiki sebelum top-up ke tekanan operasi yang betul. Jika gegelung kotor, cuci kimia memulihkan pertukaran haba. Jika kapasitor rosak, ia diganti di tempat. Sebut harga telus diberikan sebelum kerja bermula.

FAQs · Soalan Lazim · 常见问答
Low gas is the most common cause, but a dirty coil or faulty capacitor can produce the same symptom. KL Renovator diagnoses all three before recommending a solution — you pay for what you actually need.
If it is low gas: gas top-up from RM 2.50/PSI (R22), RM 3.00/PSI (R410A), RM 3.00/PSI (R32). If it is a dirty coil: chemical wash from RM 120. If it is a faulty capacitor: RM 180 replacement. Diagnostic fee RM 88 (waived if repair done same visit).
Yes. Most causes of an aircond not being cold — gas top-up, chemical wash, capacitor replacement — are done in one visit. KL Renovator carries common parts on the van.
Yes, short-term, but it wastes electricity — a unit low on gas still draws full power while cooling poorly, and running it for weeks with a leak can eventually damage the compressor. Get it checked within a few days rather than waiting months.
Not usually — if your existing correctly-sized unit suddenly stopped cooling well, that's almost always a fault (gas, coil, capacitor), not an undersized unit.
You usually can't tell from outside — low gas, a failing outdoor compressor, and a dirty indoor coil can all produce the exact same "blowing but not cold" symptom.
It can, since older non-inverter compressors work harder and show wear sooner, but low gas and dirty coils affect inverter units just as often.
🇲🇾 Bahasa Malaysia
Gas rendah adalah punca paling biasa, tetapi gegelung kotor atau kapasitor rosak boleh menghasilkan gejala yang sama. KL Renovator mendiagnosis ketiga-tiganya sebelum mencadangkan penyelesaian.
Jika gas rendah: top-up gas dari RM 2.50/PSI (R22), RM 3.00/PSI (R410A), RM 3.00/PSI (R32). Jika gegelung kotor: cuci kimia dari RM 120. Jika kapasitor rosak: penggantian RM 180.
Ya, buat sementara, tetapi ia membazir elektrik. Dapatkan pemeriksaan dalam beberapa hari, bukan menunggu berbulan-bulan.
Biasanya tidak — ini hampir selalu kerosakan (gas, gegelung, kapasitor), bukan unit terlalu kecil.
🇨🇳 中文
气体不足是最常见的原因，但脏污的盘管或故障的电容器也会产生相同症状。KL Renovator会先诊断全部三项，再提供建议。
如果是气体不足：充气从 RM 2.50/PSI（R22）、RM 3.00/PSI（R410A）、RM 3.00/PSI（R32）起。如果是盘管脏污：化学清洗从RM 120起。如果是电容器故障：更换RM 180。
短期内可以，但会浪费电力。建议几天内检查，而非拖延数月。
通常不能——几乎总是故障（气体、盘管、电容器）问题，而非机型太小。
