Air Conditioner Conservation Device

This simple device can trim up to 30% off your air conditioning bills. It needs no power and you can install it — without tools — atop almost any central air conditioner. Whenever your AC comes on, a special valve releases a fine mist, which evaporates instantly to lower ambient air temperatures by up to 30 degrees. Your system will transfer heat to the air outside faster, run less often and use less energy, which saves you money and reduces your carbon footprint. USA.
