Do we need to refill gas in AC?

Best answer
Yes, over time, the refrigerant (the "gas" in an AC) can slowly leak out or degrade, which may cause your AC to lose its cooling efficiency. If this happens, you may need to refill or recharge the refrigerant. However, under normal conditions, an AC should not need frequent refilling if it’s working properly and there are no leaks.

If your AC isn’t cooling as well as it used to, it could be a sign that it needs a refill or that there is a leak in the system. It's best to have a professional technician check it to ensure everything is working correctly.
