With temperatures regularly above 45°C, Dubai air conditioners run almost non-stop through summer. That constant load makes certain faults far more common between May and September.
Weak or No Cooling:
- Caused by low refrigerant, dirty coils, or an overworked compressor
- The most reported summer complaint in Dubai homes
- Regular servicing before summer prevents most cases
Frozen Coils:
- Dirty filters and low gas cause the indoor coil to ice over
- Leads to water leaks and reduced airflow
- Clean filters monthly to keep airflow strong
Water Leaks:
- Blocked drain lines overflow under heavy condensation loads
- Summer humidity makes this far more frequent
- Drain flushing during servicing keeps lines clear
High Electricity Bills:
- A struggling or dirty AC works harder and uses more power
- DEWA bills spike when units run inefficiently
- Maintenance and correct temperature settings cut costs
Compressor Overheating:
- Extreme heat plus dirty condenser coils strain the compressor
- Can cause sudden shutdowns or permanent failure
- Keep the outdoor unit clean and shaded where possible
Strange Noises and Smells:
- Rattling, buzzing, or musty odours signal mould, debris, or loose parts
- Often appear after months of heavy use
How to Prevent Summer Breakdowns:
1. Service your AC before the hot season starts 2. Clean or replace filters every 1–2 months 3. Keep the outdoor unit free of dust and obstructions 4. Set a steady temperature around 24°C instead of very low 5. Book professional cleaning at least once a year
When to Call a Professional:
If cooling drops, bills climb, or you hear unusual sounds, early servicing prevents a full breakdown during peak heat—the worst time to be without AC.
