HOW to use air conditioner cooling more useful?
If possible find a way to spray a mist of water on the condenser coils outside. This will cause them to lose heat more rapidly and efficiently. I did this on my window unit at my flat and it made a phenomenal difference in cooling efficiency. You will have to purchase a small 12volt controlled nozzle like those used for automatic sprinkler systems and some small plumbing parts. If you’re clever with electronics you should be able to wire it up to the compressor’s own 12volt relay system as it was available on mine. Most of the control circuits in today’s AC units are 12 or 24 volt. Good Luck!
