AC grinding, not cooling: DIY fix or call a pro?« Back to Previous Page

Based on your description, this is not a simple DIY fix. A grinding noise coupled with a significant loss of cooling capacity and a spike in your DEWA bill points to a serious mechanical issue. In Dubai's climate, where AC systems run year-round and combat extreme dust and humidity, neglecting such symptoms can lead to a complete system failure or costly water damage.

While cleaning the filter is essential monthly maintenance, it will not resolve a grinding sound. This noise typically indicates a failing motor in the indoor blower fan or, more critically, the compressor in the outdoor unit. These are complex components requiring professional diagnosis and repair. Furthermore, the inability to cool below 25°C suggests a potential refrigerant leak or a frozen evaporator coil, both of which need specialized tools and certified technicians to address safely and effectively.

For a standard split AC unit service in an older Bur Dubai apartment, a reasonable price for a professional inspection and basic clean-up should range from AED 250 to AED 400. However, be prepared for additional costs if parts like capacitors, motors, or a refrigerant recharge are needed. Reputable companies will provide a transparent quote after inspection.

Given the symptoms, I strongly recommend you cease operation of the unit to prevent further damage and call a professional immediately. Our team at Saniservice is equipped to diagnose and resolve exactly these kinds of AC issues, ensuring your system operates efficiently and your indoor air quality is not compromised.
