Here are the proper steps to check a window AC gas level:
First, switch off the AC and unplug it. Remove the front cover to access the unit's internal components.
Next, find the access panel on the side of the AC and open it. You will see the refrigerant service points there. Now connect the pressure gauges.
Fix the blue gauge to the low-pressure valve and the red gauge to the high-pressure valve.
After connecting the gauges, read the pressure levels carefully. If the high pressure is much higher than normal, the system may have too much refrigerant or poor airflow.
If the low pressure is lower than normal, the AC may have less refrigerant than needed. The correct pressure depends on the outside temperature and the AC model.
If the low pressure shows low refrigerant, add refrigerant slowly and carefully. If the high pressure is too high, do not add refrigerant.
Instead, check for air blockage or excess refrigerant in the system. Always follow the recommended limits to keep the AC working safely and properly.
Hope this helps you.

Here is how to check gas level in window AC:
First, switch off the AC and unplug it for safety.
Then, locate the service valve, which is usually found near the compressor at the back of the unit.
Next, connect a manifold gauge set to the service valve. After fixing the gauge properly, turn on the AC and let it run for a few minutes. Observe the pressure reading shown on the gauge.
In most cases, a normal reading falls within the manufacturer's recommended range. Low pressure usually indicates low gas levels.
You should also check the cooling performance. If the AC blows warm air, takes too long to cool, or forms ice on the pipes, the gas level may be low.
How to Check Window AC Gas Level?
To calculate gas requirement, technicians consider temperature and pressure. When the temperature rises above the standard level, the system may need extra refrigerant. Similarly, if the pressure drops below the normal range during full operation, the AC may require gas refilling based on its cooling capacity.
Since window ACs are mostly sealed units, only a trained technician should add or refill refrigerant. Incorrect handling can damage the AC and cause safety risks. For best results and safe operation, always contact a professional AC service expert to check and refill the gas if required. Hope this helps you.
