I don’t know where you live, but here in Southern Indiana, electricity bills this time of year tend to soar due to heavy use of air conditioner units. Keeping your home cool is a must when humidity levels are high and temps are in the 90’s. How can you optimize your AC unit to save money on your monthly power bill? Keeping doors and windows shut and your blinds closed during the day can help a little. But Mistbox is a gadget that connects to your outdoor AC unit and could save you up to 30% on your monthly bill. Mistbox consists of a water pump and four sprayer arms that attach to the sides of the AC unit to spray a fine mist of cold water when the AC unit is running. The water mist cools the surrounding air around the AC unit, making it easier and faster to cool your home. Sound like snake oil? I hope to fine out. They have sent me one to try. I set it up yesterday, so I’ll have a review in a few weeks. The unit is priced at $399 from mistbox.com or Amazon.
