BACKGROUND OF THE INVENTION
This invention/method relates to an exhaust fan or air ventilator, specifically to such ventilation systems which remove air from the Air conditioning (HVAC) ducts. This invention as best I can tell is in the Classification Definitions Class 454, sub-classes 230,233. Some prior art which may relate to this invention/concept is U.S. Ser. No. 04/776,385 Air Ventilation Control System. This unit appears to pull in the outside air then exhaust the air to the exterior. U.S. Ser. No. 05/934,362 Combination Bath Fan, Register Box, Air Conditioning and Heat Boot. This invention removes the air from a room and vents to the exterior. The Air Duct Evacuation System (ADES) will remove the air from the ducts and vent to the exterior, attic or crawl space.
BRIEF SUMMARY OF THE INVENTION
This invention will remove the air within the ducts of an air-condition/furnace (HVAC) system. The air is removed just minutes prior to the HVAC system cycling on so as to rid the air in the ducts, which has become either hot or cold while resting in the ducts of the buildings attic or crawl space.
In removal of the stagnate air in the ducts this will allow for cooler air (in the summer) or warmer air (in the winter) to reach the interior of homes or businesses faster. This will also mike for a more allergy friendly building.
