Aircond Gas Refill & R32 Top-up in KL & Selangor
When your aircond isn't cooling, gas is often the suspected cause — but it isn't always the actual cause. A dirty coil blocks airflow and mimics the same symptoms as low refrigerant. A clogged drain can restrict the unit and trigger shutdown. A failing compressor won't cool regardless of how much gas you put in. That's why we always pressure-check and diagnose before we touch the refrigerant lines. Refilling a system without identifying the root cause is a waste of your money — the gas you pay for today will be gone in days if there's an unrepaired leak.
When you need a gas refill
The following symptoms point toward a refrigerant issue and are worth investigating with a pressure check:
- Weak cooling despite a clean filter and unblocked vents.
- Ice formation on the copper pipes running to the indoor unit.
- A hissing or bubbling sound near the indoor or outdoor unit.
- Fault codes E1 or E2 (or similar) on inverter unit displays.
What these symptoms are not: a dirty evaporator coil causes weak cooling and should be resolved with a chemical wash. A drainage blockage causes water dripping and reduced performance and needs a drain repair. Compressor failure causes complete loss of cooling and requires compressor assessment or unit replacement — gas refill will not fix a dead compressor.
Our gas refill process
- Pressure check and leak detection. We test the system pressure before anything else. If pressure is low, we use UV dye or soap testing to locate the leak. We do not refill without identifying the source first — refilling a leaking system is a temporary fix that costs you money repeatedly.
- Repair the leak. Once the leak is located, we repair it on-site (typical flare joint or pipe joint leak) or provide a quotation if it's a compressor-side fault or if system replacement is the more cost-effective route.
- Vacuum the system. Before refilling, we pull a vacuum on the refrigerant lines to remove moisture and air. Skipping this step introduces contamination that degrades the refrigerant and damages the compressor over time.
- Refill to manufacturer specification. R32 for most modern residential units, R410a for some older systems, R22 for legacy units (phased out globally — we carry limited stock and will advise on unit replacement for older R22 systems).
- Performance test. After refill, we measure return-air temperature, supply-air temperature, and system pressure across a full cooling cycle to confirm the unit is operating within spec.
Pricing
- R32 top-up: RM150 per unit (1–2 HP residential)
- R410a top-up: RM180 per unit
- Leak repair: site-quoted after the pressure and leak test — the price depends on where the leak is and how accessible the joint or pipe run is
- Inverter compressor replacement: site-quoted after diagnostic
All prices are upfront and quoted on WhatsApp before we send a technician. The quote you receive is the price you pay.

When you do not need this
We would rather tell you not to book than sell you something that will not fix the problem.
- The system holds pressure. If the pressure test is normal, the problem is not refrigerant and we will say so rather than sell you gas. Nine times out of ten the answer then is a chemical wash.
- You have already topped up twice in a year. That is not a gas problem, it is an unrepaired leak. Repeated top-ups cost more than fixing the joint and vent refrigerant into the atmosphere.
- The compressor is not running at all. Gas will not start a dead compressor. That needs a repair diagnosis first.
- The unit is R22 and near end of life. R22 is being phased out, supply is limited and expensive, and on a tired unit the money is usually better spent on replacement.
What changes the final quote
The published price covers the standard job. These are the things that move it, and all of them are confirmed with you before any work starts:
- Refrigerant type. R32 on most modern units, R410A on some older systems, R22 on legacy units - they differ in cost and availability.
- How much has been lost. A system that has emptied completely needs a full charge by weight, not a top-up.
- Where the leak is. A flare joint at the indoor unit is straightforward. A leak in a concealed pipe run, in the coil itself, or on the compressor side is a much bigger job - which is why leak repair is quoted on site after the test.
- System size. Charge is by weight to manufacturer specification, so a larger system takes more refrigerant.
Warranty and its limits
Leak repairs carry a 30-day leak warranty: if the same leak returns within 30 days, we come back at no extra charge. What the warranty cannot cover is a different leak developing elsewhere in an ageing system - on units over about 10 years old, a repaired joint does not make the rest of the pipework new. We will tell you honestly on site when that is the likely outcome.
FAQ
My aircond uses R22. Can you still refill it?
Yes, with caveats. R22 refrigerant is being phased out globally under the Montreal Protocol, and supply is increasingly limited and expensive. For older R22 systems, especially those showing other signs of wear, unit replacement is often more cost-effective than continued R22 top-ups. We will advise you honestly on the trade-off when we inspect the unit.
Why do you check for leaks before refilling?
Because if there's a leak in the refrigerant circuit, the gas you pay for will escape in days or weeks. You would be paying for a refill repeatedly without solving the problem. Identifying and repairing the leak first means the refill lasts as long as it should — years, not weeks. It also protects the environment; refrigerant release is regulated for good reason.
Can I just top up without a full service?
We always pressure-check before refilling — that's not negotiable. It takes 15 minutes and protects your investment. If pressure is within acceptable range, we'll tell you and may recommend a chemical wash instead. If pressure is low, we identify the leak before we refill. There is no safe way to skip this step.
How long does a gas refill take?
45 to 90 minutes per unit, including the pressure and leak check, vacuum, refill, and performance test. If a repair is needed first, the total time will depend on the nature and location of the leak — we'll advise on-site.
