Refrigerants in UAE AC units: what is obsolete, what we refill, why top-ups are not petrol.

Tip: send a photo of the indoor and outdoor unit on WhatsApp before we quote extras.

R22

Old splits. Import is effectively over. If your outdoor sticker says R22, plan a future replacement. We do not treat R22 as a normal stock top-up.

The common previous-generation blend. High pressure. Leaks still matter. We refill when the system is sound enough to hold it. Gas refill prices.

Many new splits. Mildly flammable classification — we handle it as trained work, not as a kitchen experiment. Charge to the nameplate.

If it is low, it leaked or was never commissioned. Yearly top-ups without a leak conversation waste money and compressors.

Warning: do not poke live terminals or recover refrigerant yourself. Isolation first, then WhatsApp.

Can you convert R22 to R32?

Not as a casual drop-in. Oils, pressures, and legal charge differ. Replacement is usually cleaner.
