Or perhaps your home unit doesn't quite cool as well as you would like? This 12,000 BTU 115-volt air conditioner with remote from KoolKing is ideal to use in your bedroom during those warmer nights. If you're simply looking to improve the airflow in your home, then you can use the fan setting to help circulate air.
