Most AC repairs in Dubai are one of about a dozen root causes. This hub walks through how to identify what's actually wrong before a technician arrives, what a fair quote looks like, and the failure modes that mean the unit is finished rather than fixable. Read the relevant spoke article for the symptom you're seeing.
Key takeaways
- Diagnostic callout is AED 190 in Dubai — waived if you approve the repair on the spot
- 70% of 'AC not cooling' calls are dirty filters, blocked drains, or low gas — none of which need a new unit
- Replace rather than repair when the compressor fails on a unit older than 8 years
- Emergency response in 60–90 minutes is standard across central Dubai; ad-hoc weekend calls cost more
Diagnose before you call
Spending five minutes on a basic check before you book a technician will frequently save you the callout fee. The four things to check, in order: filter, breaker, thermostat batteries, outdoor unit airflow. Roughly a third of 'AC not working' calls are solved by one of those.
If the unit is still not cooling, the symptom narrows the diagnosis. Use the table on the spoke article below to match what you're seeing to the most likely cause.
- AC runs but doesn't cool → likely low refrigerant or clogged coil
- AC turns on then trips the breaker → compressor draw or wiring issue
- Water dripping inside → blocked drain line (most common)
- Loud humming or rattle → fan motor bearing or loose mount
- Burning smell → stop immediately, isolate at the breaker, call same day
What a fair repair costs
Repair pricing in Dubai is unregulated, which is why quotes vary wildly. Freshair publishes flat diagnostic and service rates and quotes parts at cost. As a sanity check, here is what most common repairs land at when done by a licensed company with insurance.
- Drain line unblock: included in any service visit
- Capacitor replacement: AED 190 callout + AED 80–180 part
- Fan motor replacement: AED 190 callout + AED 350–650 part
- Refrigerant leak repair + recharge: AED 190 + AED 250–500 depending on circuit
- Compressor replacement: AED 1,500–4,000 — usually the break-even moment for a new unit
When to repair, when to replace
The rule of thumb most engineers use: if the repair quote exceeds 50% of the cost of a new equivalent unit, and the unit is older than 8 years, replace. R-22 units that need a refrigerant top-up should always be replaced — the gas is phased out and refills are expensive and getting harder.
A modern R-32 inverter split is usually 35–45% more efficient than a 10-year-old unit. The energy saving alone repays the upgrade within 3–4 summers in Dubai.
Getting same-day or emergency help
During summer, every technician in Dubai is fully booked by 10am. The difference between a 60-minute response and a 24-hour wait is whether you booked through a provider that protects emergency capacity. Our Comfort and Premium AMC tiers include guaranteed emergency response (60–90 min and 2–4 hours respectively).
