Blowing warm air? We top up R22, R32, or R410A refrigerant to the manufacturer's pressure — with a leak test done first, every time. Honest fix in 30–60 minutes, residential and commercial across all 24 KL districts.
An aircond gas top-up recharges your unit's refrigerant — R22, R32, or R410A — back to the manufacturer's pressure using a manifold gauge at the service port. The important part: refrigerant doesn't "run out". It runs in a sealed loop, so a low charge means there's a leak. That's why we always run a leak test first. A top-up gets your cooling back in 30–60 minutes, but if we find a major leak, topping up alone won't hold — we'll quote the repair too. No "gas refill" gimmicks, just an honest diagnosis.
Every gas top-up we do in Kuala Lumpur follows the same six-step scope, residential or commercial. Pressure readings and outlet temperatures recorded on the job sheet and sent on WhatsApp.
We read the outdoor unit's rating plate to confirm R22, R32, or R410A. Mixing refrigerants damages the system, so we never guess.
Flare joints, copper piping, and the coil are checked for leaks before any gas goes in. Gas doesn't vanish on its own — we find where it's escaping.
A manifold gauge is connected to the service port to read the standing pressure, so we know exactly how undercharged the unit is.
Refrigerant is added slowly and metered to the manufacturer's spec for that exact unit — not "until it feels cold". No overcharging.
We measure the vent temperature before and after the top-up. A correctly charged 1.5HP split should hit a clear drop you can feel immediately.
Final pressure and both temperature readings are recorded on the job sheet. If a leak was found, the repair quote is attached in the same WhatsApp.
If any one of these applies, the charge should be checked with a gauge — not topped up blindly. Two or more usually means a leak is involved.
The classic symptom. The fan still blows, but the air isn't cold. With too little refrigerant the coil can't pull heat out of the room.
A low charge drops the coil temperature below freezing and moisture frosts over. If you see ice on the pipes outside, stop the unit and call us.
The room takes far longer to cool, or never reaches the set temperature even on a normal KL afternoon. The system is starved of gas.
An undercharged unit runs almost non-stop trying to hit the thermostat. You'll notice the compressor outside rarely cycles off.
Running constantly for weaker cooling burns more power. A KL household running two undercharged 1.5HP units can see the bill creep up month on month.
A faint hiss can be refrigerant escaping through a leak point. It's a clear sign you need a leak test, not just a top-up.
Whether it's a condo in Mont Kiara or a cafe in Bangsar, the method is the same — leak test, gauge, charge to spec. Only the unit count and access change.
Apartments, condos, and landed homes. Most calls are a single bedroom or living-area split blowing warm air. We confirm the refrigerant, leak test, and charge to the OEM pressure for that exact model — usually 30–45 minutes.
F&B outlets, retail, clinics, and offices where a warm unit means lost customers. Higher run hours surface leaks faster, so we prioritise the leak test and quote any repair on the spot to keep the space cold.
Tell us what's happening — warm air, ice on the pipes, weak cooling — and send a photo of the indoor unit and the outdoor rating plate if you can reach it.
Quote covers the leak test, the top-up, and total time. No verbal estimates. Sent on WhatsApp so it stays in your chat history.
Same-day dispatch if confirmed before 4 PM; otherwise next-day. We send arrival ETA on the morning of the visit.
Six-step scope above. Leak test first, then charge to OEM pressure with a manifold gauge. Outlet temperature measured pre and post, logged on the job sheet.
3-month labour warranty issued on WhatsApp. If a leak means the top-up won't hold long-term, you get the repair quote up front — no surprises.
Refrigerant doesn't get used up like fuel — it runs in a sealed loop. If the charge is low, gas has escaped through a leak, usually at a flare joint, the copper piping, or a corroded coil. That's why we always run a leak test before topping up R22, R32, or R410A back to OEM pressure. A top-up gets cooling back fast, but if there's a major leak it won't hold, so we quote the leak repair at the same time. No "gas refill" gimmicks.
About 30 to 60 minutes per unit. That covers the leak test, connecting a manifold gauge to the service port, charging the refrigerant to the manufacturer's pressure, and checking the outlet temperature before and after. Final pressure is logged on the job sheet so you have a record.
The most common signs are warm or lukewarm air from the unit, ice forming on the copper piping or the indoor coil, slow or weak cooling, longer run times, a higher electricity bill, and sometimes a hissing sound near the unit. Any one of these means the charge should be checked with a gauge — not topped up blindly.
We top up R22, R32, and R410A — the three refrigerants found in almost every residential and light-commercial unit across Kuala Lumpur. We confirm the type from the outdoor unit's rating plate before charging, because mixing refrigerants damages the system. Pressure is measured with a manifold gauge at the service port and restored to the OEM spec for that exact unit.
