In Dubai a small refrigerant top-up for one unit runs AED 150-3004, and a standard refill with checks is AED 250-600+ per unit5. The diagnostic visit before it is AED 100-2003. A Dubai maintenance provider quotes a recharge at AED 200-4009.
What should a refill cost?
The price depends on what the technician does besides connecting a cylinder. A cheap job is a top-up and a temperature check. A thorough one puts the system under pressure, tests the joints and records the readings so the next visit has something to compare against.

Why does your AC keep needing gas?
Almost always, a leak. The price guide is clear on this: AC refrigerant should not need routine refilling in a sealed system6. A closed circuit that has lost enough charge to stop cooling has a hole somewhere, often at a flare joint, a valve or in the coil.
Paying for a top-up every year means paying to put off a repair. On an old unit in a flat you are leaving soon, that can be a reasonable choice. On a system you plan to keep, it usually costs more over time.
What should happen before anyone adds gas?
- The fault is confirmed as low charge, not a dirty coil or a failed fan. All three feel like weak cooling.
- Pressures are read and written down.
- Joints and the coil are checked for leaks, and you are told where the gas is going.
- You get the refrigerant type in writing. The price guide notes that R410A is common in many split ACs, R32 appears in some newer systems, and R22 is an older HCFC refrigerant being phased out globally8.
If nobody can tell you where the leak is, expect to pay for another top-up next summer.
What about older R22 units?
R22 is being phased out, and the price guide's advice is direct: Repeated R22 refill on an old leaking unit may not be economical compared with repair or replacement planning7. On an old unit that keeps leaking, money spent on refills is money not spent on fixing or replacing it. The repair cost guide covers when replacement is worth discussing.
Does a maintenance contract cover it?
Usually not. The price guide lists gas recharges, spare parts, duct cleaning and after-hours call-outs1 as usually outside a Dubai contract, with a recharge charged at AED 200-4002 on top. Some plans include a set top-up allowance. Ask for it in writing, because "gas included" and "one top-up a year included" are different promises at a similar price. The AMC guide covers the other exclusions.
Renting?
A refrigerant leak is a fault in the system rather than routine cleaning, so under Dubai law's default rule it falls on the landlord's side unless the lease says otherwise. The details, including what a lease can change, are in who pays for AC repairs in a Dubai rental.
