Abstract
An access door to an air handler unit is provided, having a double seal set in the door frame. The double seal is composed of an outer seal which provides a moisture barrier, having an aperture to permit air to pass through, and an inner seal which provides an air barrier. The inner and outer seal are spaced apart to provide an air gap therebetween. A lip is provided along the side and top of the door to shed water away from the outer seal. The door is hingedly supported in the frame, where the outer surface of the door comes in sealing contact with the outer seal and the inner surface of the door comes in sealing contact with the inner seal when the door is closed. A set of door handles is provided to lock the seals in place when the door is closed and latched properly.
