Why Your AC Stops Working in Dubai’s Heat
Living in Dubai means dealing with high temperatures most of the year. When your air conditioner breaks down, it quickly becomes more than an inconvenience. Understanding common AC issues can help you fix problems fast or know when to call a professional.
Air conditioners in Dubai work overtime, especially during summer months when temperatures can reach 50°C. This heavy usage leads to specific problems that affect cooling performance and efficiency.
