Abstract: A fan motor or blower unit attached and manufactured as part of the heating and cooling systems for homes and buildings or attached later to the furnace or air handler, which will vent out the HVAC ducts by removing the residing air. This air duct evacuation system will remove the unwanted warm or cool air from the building or structures air conditioning and heating duct systems, allowing for easier heating and cooling and more allergy friendly building or structure. The ADES will be on a relay switch or temperature controlled thermostat. The ADES will have a motor or blower unit able to pull the amount of the air per cubic feet per minute needed to vent the duct system. The main frame will have insulating stripping around the perimeter to prevent air leakage as well as a self closing and insulative exhaust flap doors. Surrounding the fan blades is a metal wire cage for safety of the blade operation.
