Here is how to check if AC is cooling properly:
First, check the thermostat settings: Always set the AC to cool mode. If you select fan or heat mode, the AC will not cool the room. Set the temperature a few degrees lower than the room temperature. Also, keep the fan setting on auto, not on “on,” so the AC cools better.
Next, feel the air coming from the AC vents: The air should feel cool within 10 to 15 minutes after switching on the AC. You can also use a thermometer. The air from the AC should be about 8 to 12 degrees cooler than the room temperature. If there is very little difference, the AC may be malfunctioning.
Then, check the air filter: A dirty filter blocks airflow, reducing cooling. Remove the filter and clean it if you see dust and dirt. Clean filters help the AC cool faster and save electricity.
After that, look at the outdoor unit: Remove dust, leaves, or any items blocking airflow. Make sure the outdoor unit has enough space around it to release heat.
You should also watch for signs of gas problems: If you see ice on the pipes or hear hissing sounds, the AC may have low gas. In this case, always call a professional technician.
Finally, listen for unusual sounds or bad smells: These signs can mean internal issues. If basic checks do not help, book AC service for proper inspection and repair.
Regular checks keep your split AC cooling properly and increase its life.

Sometimes your air conditioner may feel like it’s not cooling enough, even though it is working properly.
One reason is room habits and environment. Keeping doors and windows closed while the AC is running prevents warm air from entering, which helps the room cool faster.
Using curtains or blinds to block direct sunlight reduces the heat load, and avoiding heat-generating appliances like ovens, irons, or lights while the AC is on keeps the room cooler.
A properly working AC should be able to cool a standard-sized room within 20 to 30 minutes. However, the AC may struggle if it is undersized for the room. For example, a 1-ton AC in a large living room will take longer to cool and may feel weak, even though it is functioning correctly.
Understanding these factors helps explain why cooling may feel inadequate. Hope this helps you.
