Why Car AC Fails in Dubai Summers (And How to Avoid It)

Dubai’s summer isn’t just hot—it’s a car AC assassin. With temperatures hitting 50°C and sand clogging filters, even luxury cars gasp for cool air. At Sunshine Auto Repair, a leading car repair in Dubai workshop, we’ve seen AC failures triple between June-August. Here’s why:
- Dust & Sand: Clogs condenser coils faster than anywhere else.
- Overworked Systems: ACs run 12+ hours daily, straining compressors.
- Old Refrigerant: 60% of Dubai cars use outdated R134a gas.
“Most AC breakdowns here are preventable with basic care,” says Ali Hassan, lead technician at Sunshine Auto Repair.”
DIY Fixes: Cool Down Your Car Fast
1. Clean the Cabin Air Filter (15-Minute Hack)
- Symptoms: Weak airflow, musty smells.
- Steps:
- Locate filter behind glovebox (YouTube your car model).
- Tap out sand; replace if torn.
- Reinstall and test.
Pro Tip: Dubai drivers should clean filters every 3 months vs. the standard 12.


2. Check Refrigerant Levels
- Tools Needed: AC pressure gauge ($20 at ACE Hardware).
- Safe PSI Range: 25-45 (varies by car).
Warning: Overfilling can burst hoses. When in doubt, visit Sunshine Auto Repair for Car AC Repair & Works in Dubai.
