Questions & Answers

Frequently Asked Questions

Why is my AC running but not cooling?

Common causes include low refrigerant (gas leak), dirty evaporator or condenser coils, faulty compressor, sensor issues, clogged air filters, or electrical/PCB problems. Our technicians perform a thorough diagnosis to identify the exact root cause.

How long does it take to repair a not-cooling AC?

Most cooling repairs take 1-3 hours depending on the issue. Simple fixes like cleaning or sensor adjustment are quicker, while compressor or gas leak repairs may take longer. We provide a time estimate after diagnosis.

Do you top up refrigerant during repair?

If low refrigerant is detected, we first identify and fix the leak, then refill the gas to the correct level. We never simply top up without fixing the leak, as that would only be a temporary solution.

Can clogged coils or filters cause this problem?

Yes, dirty filters and clogged coils are very common causes of weak cooling. They restrict airflow, causing the evaporator coil to freeze and reducing cooling efficiency. Regular cleaning can prevent this issue.

Are all brands covered?

Yes, we support all major aircon brands including Daikin, Mitsubishi, Panasonic, LG, Fujitsu, Toshiba, Samsung, Midea, and more. Our technicians are trained to handle various system types and configurations.

Is it safe to continue running an AC that's not cooling?

No, running an aircon that isn't cooling properly can strain the compressor, increase electricity bills, and cause further damage. It's best to turn it off and schedule a repair to prevent complete system failure.
