Who this is for
You've been told your AC needs a gas refill. Someone may have already quoted you a price and you have no idea if it's fair, what type of gas is even in your unit, or whether you'd know if they put the wrong type in. This is the background you need before letting anyone open your outdoor unit.
First: find the sticker on your outdoor unit
Go outside and look at your outdoor AC unit. On the side or back panel there's a specification sticker. It will say something like "Refrigerant: R32" or "Charge: R410A 900g". That's the number that matters. Every AC sold in Saudi Arabia must have this label. If yours is unreadable from age, a technician can determine the type from pressure readings — but in most Al Malqa villas I service, the sticker is there, just never looked at.
The three refrigerant types
R22 — the old type, becoming expensive and scarce
If your AC was installed before 2016–2018, it almost certainly uses R22. This was the standard residential refrigerant for decades. The problem: R22 damages the ozone layer and has been phased out globally under the Montreal Protocol. Production has stopped in most countries. The gas now available for R22 refills is either stockpiled or recovered from decommissioned systems — which means prices keep rising year on year.
If your AC uses R22 and is more than 10 years old, the economics of repeated refills start to look different against replacing with a modern R32 unit. See our gas refill service.
R32 — the current standard in new ACs
If you bought a split AC in Saudi Arabia after 2018, it almost certainly uses R32. LG, Samsung, Daikin, Gree, Carrier — all moved their mainstream residential lines to R32 around 2016–2019. R32 has zero ozone depletion, lower global warming impact than R22, and is the easiest of the three types to handle and refill safely. It's the most common gas refill job I do in Al Malqa and Al Rahmaniyah.
R410A — premium and inverter systems
R410A is used in many higher-end split ACs — particularly Daikin, Mitsubishi, and some Carrier models — and in multi-split and cassette systems. It operates at significantly higher pressure than R22 and R32. This pressure difference is why the equipment and training required to handle it correctly is more demanding, and why the refill costs slightly more.
Never mix refrigerant types. R22, R32, and R410A operate at different pressures and require different compressor oils. Putting the wrong type into your system — even a small amount — can rupture connections, damage seals, and destroy the compressor. Any technician who adds gas without checking your unit's sticker first is doing something wrong.
What a proper gas refill actually looks like
The correct process for a proper gas refill: connect gauges to check current pressure and confirm the gas type → evacuate the system completely with a vacuum pump → hold the vacuum for 15 minutes to confirm no leak → recharge with the correct gas to the manufacturer's specified weight (weighed on a scale, not estimated by feel).
What many cheap services in Riyadh do instead: connect to the service port and add gas until pressure "looks about right" — no vacuum, no leak check, no weight measurement. This leaves air and moisture in the system. Air causes oxidation in the compressor. Moisture freezes at the expansion valve. Both shorten compressor life. The shortcut takes 15 minutes. The correct process takes 45–60 minutes. When you see SAR 100 gas refill offers, you now know what's being skipped.
