Air Conditioner Running but Not Cooling? 7 Things to Check First ❄️
Your aircon is switched on and blowing air, but the room still feels warm. Before booking a technician, here are a few simple checks that may help narrow down the problem.
1️⃣ Check the mode and temperature
Make sure it’s set to COOL, usually shown by a snowflake symbol. FAN mode only circulates air.
Set the temperature below the current room temperature and allow time for cooling to start. Some units have a short compressor restart delay.
2️⃣ Check the filters
Dirty filters restrict airflow and can reduce cooling performance. Clean washable filters according to your unit’s instructions and let them dry before refitting.

If the basic checks like cleaning the filters and making sure the outdoor unit has good airflow don’t solve the problem, it may be worth having the system properly inspected. Issues such as refrigerant leaks, electrical faults, frozen coils, or a failing compressor can cause an air conditioner to run without actually cooling the room effectively. For persistent problems, arranging an air conditioning service Perth can help identify the underlying issue before it leads to a more expensive repair.
