If your AC runs but the room stays warm, begin with the simple checks: clean the filters, make sure doors and windows are closed, and confirm the temperature is set below room temperature. A clogged indoor filter or a blocked outdoor unit can restrict airflow and make cooling feel weak. In Lahore's dusty summer, these are common and often preventable causes.
If the airflow is normal but the air is not cold, low refrigerant, a leaking line, a weak capacitor, compressor trouble, or an inverter PCB/sensor fault may be involved. Do not repeatedly switch the unit on and off or top up gas without a leak test: that can hide the underlying problem. A technician should inspect pressure, drainage, electrical connections, and the outdoor unit before quoting a repair. SuperFixer charges a Rs. 500 inspection fee and confirms the repair scope before work begins.
What to note for the technician
Share the AC brand, whether it is inverter or non-inverter, how long cooling has been weak, and whether water is dripping indoors. Mention any error code, unusual noise, or recent voltage fluctuation. That evidence helps distinguish a simple airflow issue from a refrigerant, electrical, or compressor fault and makes the first visit more productive.
