Why Your AC Is Not Cooling Properly in Qatar (And How to Fix It)

Qatar's summer regularly exceeds 45°C, which means your AC is working at maximum load for months at a time. When cooling drops, here are the seven causes we see most often in Doha homes:

1. Dirty filters — the single most common issue. Filters clogged with fine Qatar dust block airflow and cause icing on the indoor coil.

2. Low refrigerant — gradual leaks reduce cooling capacity. Never just top up — always find and fix the leak first.

3. Dirty outdoor condenser coil — sand and dust accumulate on the outdoor unit, killing heat rejection.

4. Failed capacitor — a $20 part that stops the compressor or fan from starting.

5. Thermostat issues — wrong setting, dead batteries, or sensor drift.

6. Frozen evaporator coil — caused by low refrigerant or restricted airflow.

7. Failing compressor — the most expensive failure; always diagnose other causes first.

If your AC is more than 5 years old and hasn't been serviced, start with a deep clean and inspection.
