R32 vs R410A: Which Gas Does Your Aircond Use, and Why It Matters
By Mavis Eco Cool technicians · Updated 24 August 2026
Every split aircond sold in Malaysia in the last decade runs on one of two refrigerants: R410A or R32. They are not interchangeable, they cost different amounts to top up, and knowing which one your unit uses saves you from paying for the wrong job. This guide shows you how to check in thirty seconds, and what each gas means at servicing time.
The two gases in plain terms
R410A was the standard refrigerant in Malaysian split units roughly from the late 2000s to the mid-2010s. It works at high pressure, it is non-flammable, and there are still millions of units running on it — nothing about a healthy R410A unit needs changing.
R32 is the current standard. Almost every new wall-mount sold in Malaysia since around 2015–2017 uses it. It transfers heat more efficiently than R410A, needs a smaller charge for the same cooling, and has a much lower global-warming potential. It is classified as mildly flammable (A2L), which sounds alarming but simply means it is handled with proper tools and ventilation by a trained technician — in normal use inside a sealed system it is not a hazard.
If your unit is older than roughly 2010–2012, there is a third possibility: R22, which is being phased out entirely. That situation has its own decisions to make — see our guide to the R22 phase-out in Malaysia.
How to check which gas your unit uses
- Read the nameplate on the outdoor unit. Every condenser carries a sticker listing the model and, on one line, the refrigerant: R32, R410A or R22. This is definitive.
- Check the indoor unit or manual. Many indoor units carry a small refrigerant label on the side or under the front flap.
- Go by age as a rough guide only. Bought after 2017: almost certainly R32. Bought 2010–2016: most likely R410A. Older: possibly R22. The nameplate always wins over the guess.

Why it matters when your gas is low
The two refrigerants run at different pressures with different compressor oils, so they can never be mixed or substituted — an R410A system cannot be topped up with R32, and vice versa. A technician who does not check the label before connecting a cylinder is a technician to send away.
The second reason is the bill. Because the gases cost different amounts and run at different charge weights, the top-up price differs:
Both prices are charged only after a pressure and leak test. Refrigerant is not consumed in normal operation — a closed system keeps its charge for the life of the unit. If your gas is low, it leaked out somewhere, and topping up without finding the leak means paying for the same gas again in a few months. The signs are covered in aircond gas leak: the 6 signs, and the full pricing logic in gas top-up prices in Malaysia.
Does R32 make a new unit worth it?
On its own, no — do not replace a healthy R410A unit just for the newer gas. But when a unit is already at the repair-versus-replace point, the R32 generation’s better efficiency is a genuine point in favour of replacing: newer inverter R32 units cool the same room with less electricity. Installation starts from RM250 per unit — see aircond installation in KL & Selangor.
Frequently asked questions
Can I top up an R410A aircond with R32 gas?
No, never. The two refrigerants run at different pressures with different compressor oils, and mixing or substituting them damages the compressor. The correct gas for your unit is printed on the outdoor unit nameplate, and a proper technician checks it before connecting anything.
Is R32 refrigerant dangerous?
R32 is classified as mildly flammable (A2L), which is why it is handled by trained technicians with the right tools and ventilation. Inside a sealed, correctly installed system it poses no hazard in normal use, and it is the standard refrigerant in almost every new aircond sold in Malaysia today.
How do I know which gas my aircond uses?
Read the sticker on the outdoor unit: it lists the refrigerant as R32, R410A or R22. As a rough guide, units bought after 2017 are almost always R32 and units from 2010 to 2016 are usually R410A, but the nameplate is definitive. You can also WhatsApp us a photo of the sticker and we will read it for you.
How much does an aircond gas top-up cost?
R32 is from RM150 per unit and R410A is from RM180 per unit, charged only after a pressure and leak test confirms what the system needs. If the test finds a leak, we quote the leak repair before any gas goes in, because topping up a leaking system just wastes the gas.
Is R32 better than R410A?
For a new purchase, yes: R32 transfers heat more efficiently, needs a smaller charge, and has a far lower global-warming potential, which is why manufacturers switched to it. For a unit you already own, the right answer is to keep running whichever gas it was built for.
