Living in Dubai without a working AC is simply not an option. During summer, when temperatures regularly hit 45°C and above, your air conditioner works harder here than almost anywhere else in the world.
Knowing the most common AC repair problems in Dubai ahead of time can save you from sweaty nights, surprise breakdowns, and steep repair bills. This guide walks you through the top 10 issues Dubai residents face most often, and exactly how to prevent each one.
1. AC Not Cooling Properly
This is the most common complaint among Dubai residents. The AC is running, but the room just does not get cold.
Common Causes
- Low refrigerant (gas) levels
- Air filters blocked with dust and debris
- Frozen evaporator coils
Prevention
Clean or replace your air filters every 4 to 6 weeks during summer. Schedule a refrigerant check at least once a year.
2. AC Refrigerant (Gas) Leak
Refrigerant is the chemical that cools the air. When it leaks, your AC loses cooling power fast.
Signs of a Gas Leak
- AC blows warm air
- Hissing or bubbling sound near the unit
- Ice forming on the coils
Prevention
Do not skip annual maintenance. A trained technician can spot and fix small leaks before they turn into major problems. Breezy Tech HVAC includes refrigerant level checks as part of their Dubai AC maintenance services.
3. Dirty or Clogged Air Filters
Dubai’s desert air fills filters much faster compared to most other places. A clogged filter chokes airflow, makes your AC work overtime, and drives up your electricity bill.
Prevention
Check filters every month. In dusty areas such as Al Quoz or near construction zones, you may need to clean them every 2 to 3 weeks.
4. Water Leaking from the AC Unit
Water dripping from your unit is usually caused by a clogged condensate drain line.
Why It Happens
- Algae and mold grow inside the drain pipe
- The drip tray cracks or shifts out of position
Prevention
Flush the drain line during every maintenance visit. Dubai AC cleaning by Breezy Tech HVAC clears these blockages before they cause water damage to your walls or ceilings.
5. AC Making Strange Noises
A healthy AC runs quietly. Unusual sounds are your unit’s way of signaling a problem.
| Sound | Likely Problem |
|---|---|
| Banging | Loose or broken parts inside |
| Squealing | Belt or fan motor issue |
| Clicking | Electrical relay problem |
| Hissing | Refrigerant leak |
Do not ignore strange noises. Calling a technician early is almost always cheaper than waiting for the problem to get worse.
6. AC Short Cycling (Keeps Switching On and Off)
When your AC turns on and off every few minutes without completing a proper cooling cycle, that is called short cycling. It wastes energy and puts serious strain on the compressor.
Common Causes
- AC unit is too large for the room
- Dirty filters blocking airflow
- Low refrigerant levels
Prevention
Have professionals size the unit correctly before installation. Breezy Tech HVAC handles AC installation and replacement across Dubai and ensures the right unit size from the start.
7. Frozen Evaporator Coils
Even in Dubai, AC coils can freeze. This happens when airflow is restricted or refrigerant pressure drops too low.
Signs
- Warm air coming from the vents
- Visible ice on the indoor unit
- Water pooling around the unit as the ice melts
Prevention
Replace filters regularly, make sure vents are not blocked by furniture, and have coils professionally cleaned. Breezy Tech HVAC offers AC coil cleaning in Dubai to prevent this issue.
8. Electrical Problems and Tripped Breakers
AC units draw a lot of power, and the electrical systems in older Dubai buildings sometimes cannot keep up.
Typical Electrical Issues
- Capacitor failure (AC will not start)
- Contactor wear (unit does not respond)
- Breaker tripping due to power surges
Prevention
Have a qualified technician inspect your AC’s electrical connections once a year. Breezy Tech HVAC also provides electrical services in Dubai and can do a complete system check.
9. Thermostat Problems
Sometimes the AC itself is fine, and the thermostat is the real issue. A faulty thermostat sends incorrect signals to the unit.
Signs
- Room temperature does not match the thermostat reading
- AC does not turn on or off at the right times
- Short cycling behavior
Fix
Recalibrate or replace the thermostat. Upgrading to a smart thermostat is worth considering. Breezy Tech HVAC offers Nest Thermostat installation in Dubai for accurate, energy-efficient control.
10. Blocked or Dirty Air Ducts
If you have central AC or a ducted split system, dirty air ducts spread dust, allergens, and bacteria throughout your home or office.
Signs of Dirty Ducts
- A dusty smell when the AC turns on
- Uneven cooling across different rooms
- Increased allergy symptoms at home
