Aircon Gas Top Up: Price in Klang Valley and When You Actually Need One

Quick answer: Aircon Hero charges RM158 for an aircon gas top up on a 1 to 1.5 HP unit, plus RM28 per additional 0.5 HP, as listed on the Aircon Hero price list on 2026-09-06. A sealed aircond should not need routine top-ups: a low charge usually means a leak.

How much does an aircon gas top up cost in Malaysia?

At Aircon Hero an aircon gas top up costs RM158 for a 1 to 1.5 HP unit, plus RM28 per additional 0.5 HP or RM48 per additional 1 HP, with gas added charged at RM2.50 per psi, as listed on the Aircon Hero price list on 2026-09-06. Prices can change and are confirmed on site.

Gas added RM2.50 per psi Metered on the gauge

Does my aircon need gas if it is not cold?

Not necessarily. Warm air can come from a clogged filter, a dirty evaporator coil, a failed capacitor or fan motor, a faulty thermostat or a low refrigerant charge. Low gas is only one cause, so Aircon Hero runs a diagnostic, RM88 non-inverter or RM108 inverter on a wall-mounted unit, before recommending a top-up.

Gas signs: ice on the copper pipe or indoor coil, warm air with the compressor running, a hiss at a joint. Otherwise start with the causes of an aircon not cold.

Why should a sealed aircon never need a routine gas top up?

Refrigerant is not consumed like fuel. It circulates in a closed loop between the indoor coil, the piping and the outdoor compressor, so a correctly installed unit holds its charge. A low reading means gas has escaped somewhere; topping up without fixing the leak only buys time.

An annual "gas top up package" is a warning sign. A basic service at RM88 for one unit, RM78 each for two and RM68 each for three or more includes a refrigerant level check that catches a slow leak.

What does Aircon Hero check before topping up aircon gas?

Aircon Hero's CIDB-registered technicians connect a manifold gauge set to the outdoor unit, read the pressure with the compressor running, and check the flare joints and coils for leaks before adding refrigerant. A slightly low charge with no leak found is topped up at RM2.50 per psi; a leak is quoted after inspection.

  1. Switch off at the isolator; read the nameplate.
  2. Connect the gauges; read the pressure with the system running.
  3. Check every joint and both coils for leaks.
  4. Top up and re-test, or quote the leak.

Should I fix the aircon gas leak or keep topping up?

Fix the leak. Gas added to a leaking system escapes at the same rate as before, so the fault returns and the money spent on gas goes with it. Aircon Hero quotes the leak fix after inspection, and you approve the repair before work starts, with the cost known.

Daikin Malaysia's refrigerant recovery page (2026-03) says: "refrigerant recovery involves transferring the refrigerant from an air-conditioning system into a refillable cylinder during repairs or replacements." Repeated top-ups on a leaking unit are the opposite. Larger leaks go through the aircon repair service.

If your aircond is not cold, book a diagnostic, not a gas top up: the gauge and the leak check show whether a top-up will hold. If it is only due for cleaning, an aircond service with its refrigerant level check is the cheaper step; the complete guide to aircond service in Malaysia covers that visit.

Frequently Asked Questions

Never on a schedule. Refrigerant sits in a sealed loop and is not used up, so a unit that needs gas again has a leak. Aircon Hero recommends a service every 3 months for residential units; that basic service includes a refrigerant level check.

The listed rate is by horsepower, not gas type. R22 is an older HCFC being phased out under the Montreal Protocol, which Malaysia acceded to on 29 August 1989; R410A and R32 are HFCs under the Kigali Amendment, ratified by Malaysia on 21 October 2020 (UNEP Ozone Secretariat, 2025-12).

There is no fixed time, because the diagnostic comes first: the technician reads the pressures, checks for leaks, adds gas if the charge is low and re-tests, normally in one visit. A standard residential service takes about 30 to 60 minutes per unit.

No. Refrigerant is under pressure, the correct charge depends on the nameplate and the gauge reading, and the wrong type or amount can damage the compressor. Switch off at the isolator before opening any cover, and leave the gauges and cylinder to a CIDB-registered technician.

Aircon Hero's 1-month service warranty covers chemical cleaning, from the date of cleaning, so a gas top up is not covered by it. A leak found during the visit but left unrepaired is a separate fault from the top-up itself, which is why the technician quotes the leak fix before adding gas.
