AC constantly running but not cooling: recharge or replace?« Back to Previous Page

This is a very common issue we see in JVC and across Dubai, especially as we head into the peak summer months. The constant running without adequate cooling is a clear sign of a stressed system, and pinpointing the cause is critical to avoid those shocking DEWA bills.

The difference between a simple recharge and a full replacement boils down to the root cause of the low cooling capacity. A recharge (topping up the refrigerant) is only a temporary fix if there's an underlying leak. Refrigerant is not a consumable; it doesn't get "used up." If the level is low, it means it has escaped, and simply adding more will just leak out again, wasting money and harming the environment, which is against UAE regulations.

The constant running you hear is the compressor struggling to achieve the set temperature due to insufficient refrigerant or loss of efficiency. Other possibilities we frequently diagnose include a completely blocked or dirty air filter, a faulty compressor, or a frozen evaporator coil often caused by reduced airflow.

For a system in an apartment, the most common culprit is a refrigerant leak or severe loss of efficiency due to lack of maintenance. Given the symptoms you describe – constant run time, high electricity bill, and poor cooling – this is not something to guess at.

I strongly recommend a professional inspection. Our certified technicians will perform a series of tests, including pressure checks and a full system evaluation, to determine if the leak is repairable or if the unit's efficiency has degraded to a point where replacement is more cost-effective, especially considering the UAE's intense cooling demands. Don't let a faulty AC drain your wallet.
