AC Fix provides safe, compliant aircon gas refill and leak-detection services across Kuala Lumpur & Selangor — we locate leaks, vacuum & pressure test, and recharge your refrigerant to manufacturer specs for peak cooling and efficiency.
Refrigerant (gas) is the heart of an air conditioner’s cooling cycle. Low refrigerant reduces cooling power, increases energy consumption, and can damage compressors if ignored. A correct gas refill restores performance, protects components, and ensures your system runs at the efficiency it was designed for.
We treat gas work seriously: leak detection, pressure/vacuum testing, and safe recharge to the exact R32 or R410A charge specified by the manufacturer.
If you notice any of these, call for a diagnosis — usually the issue is a leak or undercharge:
These symptoms tell our technicians where to start: leak search, pressure check, and performance tests.
We treat gas work seriously: leak detection, pressure/vacuum testing, and safe recharge to the exact R32 or R410A charge specified by the manufacturer.
We follow a precise, manufacturer-aligned workflow:
Initial inspection & symptom triage — check airflow, temperature drop, and error codes.
Leak detection — visual inspection, electronic leak detector, and dye or nitrogen pressure test for hidden leaks.
Recover existing gas (if required) — capture standing refrigerant safely for legal compliance.
Vacuum & pressure test — vacuum the system to remove moisture, hold a vacuum, and perform a nitrogen pressure test to confirm no leaks.
Repair leaks (if found) — solder, replace fittings, or replace sections of piping as required.
Recharge to spec — add the correct refrigerant type and mass per manufacturer guidelines, monitor pressures and subcooling, and test performance.
Final checks & handover — record before/after temperatures, gas weight added, and give a written report + maintenance advice.
All refrigerant handling follows local regulations and safety standards. Only certified technicians perform gas work.
Licensed, trained professionals who safely handle refrigerants and follow approved air-conditioning service standards.
Gas charging is done strictly to OEM specifications, preventing over-charging, under-charging, and long-term system damage.
We identify and repair refrigerant leaks before refilling to stop recurring gas loss and unnecessary repeat costs.
Every service includes a clear diagnostic report and a workmanship warranty for complete customer confidence.
Same-day or next-day service available across Kuala Lumpur and central Selangor for urgent cooling issues.
Clean uniforms, protective covers, and a tidy workspace ensure your home or business is treated with care.
We commonly refill and service:
We always use the correct gas type for your unit and never mix refrigerant types.
Typical gas refill jobs range from RM80 for small window units to RM700+ for cassette or commercial systems; final price depends on unit size, refrigerant type and any required leak repairs.
| Service / Unit type | Typical price (RM) | Typical time | Quick note |
|---|---|---|---|
| Split (1.0 – 1.5 HP) — basic top-up / minor leak check | RM 80 – RM 180 | 30–90 min | Small top-ups, quick vacuum + recharge if no major leak |
| Split (2.0 – 2.5 HP) — standard refill | RM 150 – RM 330 | 45–120 min | Common for 2.0–2.5HP splits; includes pressure test |
| Split (3.0 – 3.5 HP) — larger split units | RM 250 – RM 450 | 60–180 min | More refrigerant + longer vacuum and performance tune |
| Ceiling / Cassette units | RM 350 – RM 700+ | 1–3 hrs | Access & panel work increase time/cost |
| Window / Wall through-unit | RM 80 – RM 200 | 30–60 min | Simpler systems — usually fastest/cheapest |
| Commercial / Multi-split / VRF | RM 500 – RM 2,000+ | varies | Quoted after site survey; depends on circuits & gas qty |
| Leak Repair + Refill (pipe/pan/fitting fix included) | RM 300 – RM 1,200+ | 1–4 hrs | Repair cost varies by pipework, brazing, parts & access |
Full diagnostic & leak detection (visual + electronic)
Recovery (if required), vacuum & pressure testing to remove moisture
Refrigerant recharge to manufacturer mass/pressure specification (R32 / R410A or specified gas)
Performance check (temperature split, pressures) and written service record
Short workmanship warranty on the repair or service
For hidden dirt or heavy coil buildup that reduces system efficiency, consider our aircon chemical cleaning:
For major component issues discovered during diagnosis (compressor, PCB, pipe replacement), book our full aircond repair service:

We provide expert aircond services throughout key regions in Malaysia.
Typically 20 to 60 minutes for a full diagnostic, vacuum and recharge. More for leak repairs.
When handled by trained technicians it’s safe. Never attempt DIY refrigerant charging.
We will top-up in an emergency, but we always recommend finding and fixing the leak to avoid repeated costs and system damage.
There’s no set schedule — a healthy system retains gas. Refill only if a leak or undercharge is diagnosed.
Yes. We provide a 1-month workmanship & water leaking repair warranty.
Yes, returning correct charge and removing blockages improves efficiency and lowers energy use.
If your AC is underperforming or showing leak signs, turn it off if you suspect a leak, take a photo of the indoor/outdoor units, and WhatsApp AC Fix now for fast diagnosis and a written quote. We priorities urgent leaks in KL & Selangor.
