Vendor availability is steady and lead times are typically short. Typical on-site time is 1–3 hours. Vendors will flag it in advance if your job looks heavier than standard.
Leak trace then recharge to spec, not a top-up guess.

The evaporator coil is designed to run cold but above 0°C, kept there by steady warm airflow across its fins. Restrict that airflow — a clogged filter, a dust-caked blower wheel — and the coil drops below freezing. Condensate that should drip into the pan freezes onto the fins, ice blocks more airflow, the coil gets colder still, and it snowballs until the unit blows a weak trickle of warmish air. Low refrigerant causes the same ice from the other direction: less gas means lower evaporator pressure and a colder coil. Two very different causes, two very different bills — a AED 150–300 clean, or a leak repair and regas — so a technician who quotes gas without checking the filter first is guessing at your expense.
August is peak icing season because the problems compound: humidity is at its annual maximum, filters carry three months of summer dust, and units run nearly 24 hours a day, so a marginal fault never gets a rest cycle to thaw. If you find ice, switch to fan-only mode for a few hours to melt it gently, put towels down, and do not chip at the fins — they are soft aluminium. Then book a proper diagnosis, because the ice returns within days if the cause is not found.
Refrigerant is not fuel. It circulates in a sealed loop and is never consumed, so a unit that needs gas has a leak — full stop. The honest version of a regas visit: find the leak with a detector or nitrogen pressure test, repair it, pull a vacuum on the lines, then weigh in the exact charge printed on the nameplate. The dishonest version is a hose, a cylinder, and see-you-next-summer. If you have paid for top-ups two years running, you have paid twice for one unfixed leak.
The gas itself matters. Older UAE units run R22 — the gas everyone still calls freon — which is being phased out under the Montreal Protocol; imports are restricted and the shrinking supply gets pricier every year, so regassing an old R22 unit can cost a startling share of its remaining value. Most systems from the last decade use R410A, and newer machines increasingly use R32, more efficient but mildly flammable. The gases are not interchangeable: R410A runs at much higher pressures than R22, so you cannot refill an old system with new gas. When a technician says an ageing R22 unit with a leaking coil is not worth repairing, the arithmetic usually supports them.
In August humidity a hard-working unit pulls several litres of water a day out of your air. All of it lands in a shallow pan under the coil and leaves through a narrow drain pipe that runs nearly flat above your ceiling, stays damp all year, and is fed a steady diet of fine dust — perfect conditions for algae and sludge. When it blocks, the pan overflows quietly into the ceiling void, and the first sign is a spreading brown stain or a drip through a light fitting. In apartments there is a twist: the stain on your ceiling is very often the upstairs neighbour's FCU, because drain trays sit in the slab void between floors. Establish whose unit is leaking before paying for repairs.
The fix is undramatic: flush and vacuum the drain line, clean the pan, check the pipe's slope, and drop in a slow-dissolving anti-algae tablet. It is a standard line in a proper service, and at AED 150–300 as a standalone job it is cheap insurance against repainting a ceiling. If a unit has overflowed once, ask about fitting a float switch — a small sensor that shuts the unit down before the pan overflows again.
whatsapp is the shortcut when the job is unusual, urgent, or you simply want a human to sort it.
Expect AED 150–700 as the working range for ac gas refill in Falaj Hazzaa. What moves it: job size, access difficulty, materials, and whether you want the value or premium tier.
| work | typical AED |
|---|---|
| Standard service, single split or FCU (filter, coil check, drain flush) | AED 150–300 |
| Full villa service, 3–5 units | AED 350–700 |
| Chemical coil wash (deep clean, per unit) | AED 200–400 |
The range narrows to an actual figure once a vendor sees the scope. You approve it before work starts.
The vetting happens before a vendor is listed — municipality licence, valid insurance, identifiable staff — so the comparison you make is between businesses that already cleared the bar.
Filters catch the coarse dust; the fine shamal fraction sails through and mats onto the wet coil and blower wheel, where a household rinse cannot reach. If airflow stays weak and bills keep climbing despite clean filters, the machinery behind them is the problem, and it needs a chemical wash.
The whole country calls a technician in the same first hot week, so June brings the year's longest waits and least negotiable prices. A March or April service finds problems while the weather is forgiving and the trade is quiet. Pre-summer maintenance is the cheapest version of every repair you will otherwise buy in August.
On a ducted system, closed supply vents raise static pressure in the ductwork rather than saving money: airflow across the coil drops, icing risk rises, and the blower strains. If a room genuinely never needs cooling, the right answer is a damper adjustment at the unit or a zoning setup, not a shut grille.
Ice on the indoor coil means the coil dropped below freezing, which has two usual causes: restricted airflow from a clogged filter or dirty blower, or low refrigerant from a leak. Switch to fan-only mode to thaw it and book a diagnosis — the ice returns within days if the cause is not fixed.
No. Refrigerant circulates in a sealed loop and is never consumed, so needing gas means there is a leak. A proper visit finds and repairs the leak, vacuums the lines, and weighs in the nameplate charge. Annual top-ups mean you are paying repeatedly for one unfixed fault.
It depends on your tenancy contract, but the common UAE convention is that minor maintenance below an agreed threshold sits with the tenant and major repairs or replacement with the landlord. In chilled-water buildings the central plant is always the owner's or provider's responsibility. Get the split in writing before you sign, and keep job reports as evidence.
Afternoon-only weakness usually means the system is losing the capacity race with peak heat: a dirty condenser rejecting heat poorly, a marginal refrigerant charge, or a unit undersized for a west-facing room. It cools fine at 38°C and fails at 46°C. Measuring the temperature split during the problem hours identifies which.
It is urgent rather than dangerous: the condensate drain is blocked and the pan is overflowing, and the water will find your ceiling or walls. Switch the unit off to stop new condensate forming and book a drain flush. In apartments, note that a ceiling stain may come from the upstairs neighbour's unit rather than yours.
