AC grinding and not cooling: repair or replace unit?« Back to Previous Page

Based on your description, that grinding noise is a major red flag. In our climate, that’s not something to ignore.

The grinding is almost certainly a mechanical failure within the compressor or the fan motor bearings. When these critical components start to fail, they draw excessive power and lose efficiency, which directly explains your lack of cooling. Simply cleaning the filter, while good practice, won't resolve a core mechanical issue.

Given the extreme demands placed on AC units in Dubai, a full compressor failure is a distinct possibility. The decision to repair or replace hinges on a professional diagnosis. Key factors include the age of the unit (units over 7-8 years are often candidates for replacement), the cost of the repair versus a new energy-efficient unit, and the availability of parts for older models.

We strongly recommend you call a technician for a comprehensive inspection before making a decision. A proper diagnosis will identify the exact source of the noise and provide you with a repair quote. This allows you to compare the cost of a repair against the long-term energy savings and warranty of a new unit.
