AC Repair & Installation in Dubai, Sharjah & Across the UAE
From a split unit that's stopped cooling to a full central AC breakdown in a villa, FETSCO's technicians diagnose and repair air conditioners across every Emirate — split, window and ducted/central systems, all major brands.
Common Air Conditioner problems we fix
Common issue
AC not cooling / blowing warm air
Likely cause: Usually low refrigerant (gas leak), a blocked condenser coil, or a failing compressor — the three most common causes we see on a first visit.
How we fix it — We pressure-test the line for leaks, clean the condenser and evaporator coils, and top up or fully recharge the refrigerant gas to the manufacturer's spec.
Common issue
Water leaking from the indoor unit
Likely cause: Almost always a blocked or disconnected condensate drain line, or a cracked drain pan on older units.
How we fix it — We clear the drain line with a vacuum flush, reseat or replace the drain pan, and check the unit's slope so it doesn't recur.
Common issue
AC making a loud or unusual noise
Likely cause: A loose fan blade, worn bearings in the fan motor, or a failing compressor — the sound itself usually tells us which.
How we fix it — We isolate the source with the unit running, then rebalance or replace the fan, or replace the motor/compressor bearing as needed.
Common issue
AC not turning on at all
Likely cause: Tripped breaker, a blown capacitor, or a faulty thermostat/PCB are the usual culprits.
How we fix it — We test the capacitor and control board first — a capacitor swap is often a same-visit fix; a PCB replacement is quoted before we proceed.
How we install your air conditioner
Site survey & load calculation
We check room size, insulation and sun exposure to confirm the right tonnage — an oversized or undersized unit is the #1 cause of poor cooling and high bills.
Indoor & outdoor unit mounting
Indoor unit leveled and wall-fixed with proper drainage slope; outdoor condenser mounted with vibration isolation and correct clearance for airflow.
Piping, wiring & vacuum test
Copper piping insulated and routed, electrical connections made to code, then the full line is vacuum-tested to remove air and moisture before gas charging.
Gas charging & performance test
Refrigerant charged to the exact factory spec, then we run the unit and measure supply/return temperatures to confirm it's cooling correctly before handover.
Genuine parts, every major brand
Air Conditioner repair — questions we get
It depends on the fault — a gas top-up and a compressor replacement are very different jobs. Our technician diagnoses on site and confirms the exact price before any repair starts, so there's never a surprise on the invoice.
Most gas top-ups, capacitor and drain-line repairs are completed on the first visit. Compressor or PCB replacements may need a part ordered, which we'll confirm during diagnosis.
Yes — we install and service split, window and central/ducted systems for villas, apartments and commercial properties.
If you're within the manufacturer's or an authorised warranty period, bring your purchase details and we'll confirm coverage before charging you — FETSCO also does warranty-backed work for several major retailers directly.
