🇲🇾 Kebocoran Gas Aircond · 🇨🇳 冷气气体泄漏
A gas leak causes repeated cooling failure even after top-ups. KL Renovator identifies the leak source, repairs the copper pipe or valve, then tops up the refrigerant to correct pressure.
Kebocoran gas menyebabkan kegagalan penyejukan berulang walaupun selepas tambah gas. KL Renovator mengenal pasti sumber kebocoran, membaiki paip tembaga atau injap, kemudian menambah penyejuk.

Direct answers
The giveaway is cooling that fades again a few weeks after a top-up. Ice on the copper, a hiss at the outdoor valves, or oily dust on a flare are the other tells. Natural loss over a decade looks different from a seasonal refill habit. Treat repeat top-ups as a leak until a detector says otherwise.
Find the point, seal it, vacuum, then charge. Skipping the first two steps is how customers pay for gas twice. KL Renovator uses an electronic sniffer and a bubble test, then quotes the joint before lighting a torch. Most flare and valve leaks finish the same day.
Finding the leak is included in the RM 88 diagnostic, waived with repair. Sealing is RM 120 / leak per leak. Recharge is extra at RM 2.50 / PSI, RM 3.00 / PSI or RM 3.00 / PSI per PSI. Extensive coil corrosion may need an indoor-unit discussion, not another patch — we say so before work.
Usually yes. Flare joints, Schrader cores and short copper runs are everyday seals. We only talk replacement when formicary corrosion has peppered a large coil. You get that recommendation in writing with the quote, not after the old unit is already on the van.
Step-by-step
Repeat-failure pattern, oil-stain map, electronic sniff and pressure-decay — then repair and vacuum before recharge.
Cooling that dies weeks after a top-up is a leak, not 'used-up' gas. Bring the last job card if you have one.
Oil travels with refrigerant. Stains at indoor flares, outdoor valves or mid-wall copper mark the search start.
KL Renovator walks the loop with an electronic detector, then confirms suspects with soap. Hidden micro-leaks get a pressure-decay hold.
We re-flare, replace a core, or braze the pinhole, pull 500 microns, then recharge. Leak repair is RM 120 / leak; gas is billed separately at RM 2.50 / PSI, RM 3.00 / PSI or RM 3.00 / PSI.
The job is not done until standing pressure holds and Cool produces a normal supply-return split.
Definitions
Short, plain-language definitions of the terms used above — written by the technicians who do the work, not copied from a manufacturer brochure.
A flare joint is the cone-shaped end formed on soft copper tubing so it can seal metal-to-metal against the unit's service valve under a flare nut. The cone must be cut square, deburred and torqued to spec. Over-tightening cracks it, under-tightening leaks slowly — which is why most refrigerant loss on a young system is found at a flare, not in the coil.
A soap-bubble test on every flare after commissioning takes two minutes and catches the leak before it costs you a top-up.
A gas top-up restores refrigerant pressure in a system that has lost charge. The technician reads the outdoor unit sticker for the gas type, connects a manifold gauge, checks static and running pressure, then charges by PSI to the manufacturer's target. Refrigerant sits in a sealed loop, so a system that needs topping up has a leak somewhere — the charge is a symptom, not the cure. R32 is priced at RM 3.00 / PSI.
If the same unit needs gas twice in a year, pay for leak detection and repair (RM 120 / leak) instead of a third top-up.
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 refrigerant gas leak will not fix itself. The unit will progressively lose cooling, eventually stop working, and the compressor will be damaged by running at low pressure. Early detection is much cheaper than compressor replacement.
Kebocoran gas penyejuk tidak akan pulih sendiri. Unit akan kehilangan penyejukan secara beransur-ansur dan pekali akan rosak. Pengesanan awal jauh lebih murah daripada penggantian pekali.
制冷剂泄漏不会自行修复。机组将逐渐失去制冷能力，最终停止工作，压缩机因低压运行而损坏。早期检测比更换压缩机便宜得多。

The Fix
🇬🇧 English
KL Renovator uses an electronic refrigerant leak detector and manifold pressure gauges to pinpoint the exact leak location. The leak is sealed — either by re-flaring the joint, brazing the pinhole, or replacing the damaged section. After sealing, the system is evacuated with a vacuum pump and recharged to the correct operating pressure. A post-repair pressure test confirms the seal before the job is complete.
🇲🇾 Bahasa Malaysia
KL Renovator menggunakan pengesan kebocoran refrigeran elektronik dan tolok tekanan manifold untuk mengesan lokasi kebocoran tepat. Kebocoran ditutup — sama ada dengan menekan semula sambungan, mematri lubang jarum, atau menggantikan bahagian yang rosak. Selepas menutup, sistem dilucut dengan pam vakum dan dicas semula.

Signs include: unit blows air but not cold, gradual loss of cooling over weeks, ice forming on copper pipes, hissing sound near outdoor unit, or visible oily residue on copper connections. WhatsApp KL Renovator at +60182983573 for same-day leak detection.
Leak detection and diagnosis: RM 88 (waived if repaired same visit). Gas Leak Repair: RM 120 per leak. Gas top-up, if required, remains charged separately by the actual PSI needed. Full breakdown is quoted before work starts.
Yes — in most cases the leak can be sealed and the system recharged. Only extensive corrosion affecting large sections of the coil would require indoor unit replacement. KL Renovator advises honestly — we do not recommend replacement unless necessary.
Leak detection is typically included in the diagnostic visit (RM 88, waived with repair). The pipe/valve repair itself ranges RM 150-400, plus gas re-charge from RM 2.50/PSI.
Yes — refrigerant flows through the whole sealed loop, so a leak can occur anywhere along it.
R32 is mildly flammable compared to non-flammable R410A/R22, but in small residential quantities with proper installation, the risk is low.
Small leaks usually don't get dramatically worse quickly, but they don't self-heal either — cooling stops entirely once gas runs out.
