Air conditioning Alternative! Quiet, low cost, energy efficient, effective! Even in the hottest months of Vermont summers the night time temperatures are typically 60 to 65 degrees (click for graph). Yet the hot air trapped in your home and attic can keep your room temperatures in the 80′s most of the night. Floor and ceiling fans help but are just pushing that hot air around. An air conditioning unit in the room may cool the air but is fighting against the heat trapped in your home structure and attic.Naturally Cool VT has the system to pull that cool evening air into your home and exhaust all the hot air from inside and the attic, dramatically cooling your entire home! Quietly, efficiently and best off all with naturally cool air. Powerful enough to exchange all the air in your home 10 to 15 times per hour! The cooler you get your entire home structure overnight, the cooler it stays throughout the next hot day.
