Aljada sits in Sharjah, and ac maintenance here has its own rhythm: access rules, parking, and timing that a vendor who knows the area already understands.
Download the appBook on WhatsAppAnyone who has arranged ac maintenance in Aljada knows the friction isn't the work itself — it's coordination. Vendors familiar with the area cut that down considerably.
Vendor availability is steady and lead times are typically short. Most ac installation jobs in this kind of area take around 1–3 hours, though access and scope shift that.
Split and window units mounted, piped and commissioned.
Everything handled in one place — quotes, booking, payment and tracking.

Rather than publishing one rate, tamam shows what multiple verified vendors charge for ac installation so you can pick the tier that fits the job and the budget.
| scope | typical range |
|---|---|
| Standard service, single split or FCU (filter, coil check, drain flush) | AED 150–300 |
| Chemical coil wash (deep clean, per unit) | AED 200–400 |
| Thermostat replacement, including standard part | AED 150–350 |
Parts and consumables, where they apply, are quoted separately and approved by you first.
Before you book anyone, work out which of three systems you live with, because the technician's scope differs completely. Villas and townhouses almost always use DX (direct expansion) systems: wall splits, or a ducted split with the air handler above a corridor ceiling and condensers on the roof. Here you own the whole refrigeration loop. Most apartment towers in Dubai Marina, Downtown, JLT, Business Bay and Al Reem use chilled water instead: a plant — the building's own, or a district cooling provider such as Empower or Tabreed — chills water centrally and pumps it to a fan coil unit (FCU) above your ceiling. There is no refrigerant in your flat at all, so nobody should ever quote you a gas top-up. What fails in an FCU is mechanical and electrical: the blower motor, the actuator valve, the thermostat, the filter and the drain pan.
The distinction matters for money as well as diagnosis. On district cooling you pay the provider for consumption and capacity, and the temperature of the water arriving at your floor is outside your technician's control. If the flat will not cool but the FCU checks out — valve opening, blower spinning, filter clean — the problem may sit at building level, which is a conversation with facilities management, not a repair bill. A good technician says this plainly instead of inventing work.
A frozen indoor coil looks like the unit is cooling too well. It is the opposite. 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.
You can judge a service visit by its sequence. A thorough technician starts with the story (what changed, when), then measures before touching anything: air temperature entering the return and leaving the supply. On a healthy DX system that split is roughly 8–12°C; a smaller gap points to low refrigerant or dirty coils, a bigger one with weak flow points to airflow restriction. It is a thirty-second test that converts a vague complaint into a number. Then the electrical checks: compressor amp draw against its nameplate figure, and the run capacitor's actual microfarads against its rating. Heat kills capacitors, making them the most commonly failed electrical part in UAE condensers — a AED 200–450 swap has rescued many units declared dead. On DX systems, gauges go on the service ports; on FCUs the checks shift to valve actuation, water flow and motor bearings.
Then the wet work: filter and coil condition, blower wheel, drain pan and line flushed and confirmed flowing, condenser fins washed from the inside out so dirt exits the way it came. A visit that skips the measurements and goes straight to hosing the filter is cleaning, not maintenance. Ask for the numbers — temperature split, amps, pressures — on the job report; a technician confident in the work will write them down, and the report becomes your baseline for next time.
A fixed-speed AC cools at exactly one rate; setting 16°C instead of 23°C does not speed it up, it just removes the finish line. The unit runs flat out for hours past the comfortable point, wasting electricity and wear. Set the temperature you actually want and let the system cycle.
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.
Vendors who let their licence or insurance lapse come off the platform. Staying listed requires keeping both current.
Twice a year is the sensible minimum: a thorough pre-summer service in March or April, and a lighter check in autumn. Villas with multiple ducted units, homes near construction, and anywhere on the coast benefit from quarterly attention. Filters are separate — wash those yourself monthly through summer.
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.
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.
That smell is biofilm — mould and bacteria growing on a coil and drain pan that stay damp for months, fed by fine dust. It is the most common indoor air complaint in the UAE and a chemical coil wash resolves most cases. If black dust also appears around the vents, add a duct inspection.
Compare like with like: ask exactly what the visit includes, since a filter rinse and a full service with coil wash, drain flush and written readings can carry the same label. Seeing several verified vendors' AED ranges side by side in the tamam app shows you where the market sits, and an outlier in either direction deserves questions.
