HVAC air freshener

An HVAC air freshener comprising:

• an elongated outer housing having at least one opening in a wall of the outer housing along a length of the outer housing, the outer housing adapted to be inserted through an opening in a planar portion of a plenum or ductwork of a pre-existing HVAC system,
• a magnet at least partially surrounding and attached to the outer housing near one end of the outer housing and adapted to magnetically attach to an exterior planar surface of the plenum or ductwork, and
• an elongated inner housing removably inserted into the outer housing, the inner housing having at least one opening in a wall of the inner housing along a length of the inner housing, the inner housing having a reservoir of fragrance liquid on one end and a wick extending from the reservoir towards the other end of the inner housing which wicks fragrance liquid from the reservoir along a length of the wick,
• the housing adapted to be located at a position within the pre-existing HVAC system such that fragrance from the wick escapes from the inner housing through the opening in the inner housing and into the outer housing, and escapes from the outer housing through the opening in the outer housing and into the plenum or ductwork to be delivered to the entirety of that portion of a home or business serviced by the pre-existing HVAC system,
• wherein the outer housing is cylindrical and includes a circular flange on the one end, and wherein the magnet is a magnetic ring encircling the outer housing and abutting the flange, such that the magnetic ring is positioned between the flange and the exterior planar surface of the plenum or ductwork when installed.

• a magnet at least partially surrounding and attached to the outer housing near one end of the outer housing and adapted to magnetically attach to an exterior planar surface of the plenum or ductwork, and
• an elongated inner housing removably inserted into the outer housing, the inner housing having at least one opening in a wall of the inner housing along a length of the inner housing, the inner housing having a reservoir of fragrance liquid on one end and a wick extending from the reservoir towards the other end of the inner housing which wicks fragrance liquid from the reservoir along a length of the wick,
• whereby fragrance from the wick escapes from the inner housing through the opening in the inner housing and into the outer housing, and escapes from the outer housing through the opening in the outer housing and into the plenum or ductwork,
• wherein the outer housing is cylindrical and includes a circular flange on the one end, and wherein the magnet is a magnetic ring encircling the outer housing and abutting the flange, such that the magnetic ring is positioned between the flange and the exterior planar surface of the plenum or ductwork when installed.

An HVAC air freshener comprising:

• an elongated cylindrical outer housing having at least one inlet opening and at least one outlet opening in a wall of the outer housing along a length of the outer housing, the outer housing adapted to be inserted through an opening in a planar portion of an HVAC plenum or ductwork,
• a circular flange on the one end of the outer housing,
• a magnetic ring encircling the outer housing, abutting the flange, and adapted to magnetically attach to an exterior planar surface of the plenum or ductwork, such that the magnetic ring is positioned between the flange and the exterior planar surface of the plenum or ductwork when installed,
• an elongated cylindrical inner housing removably inserted into the outer housing, the inner housing having at least one inlet opening and at least one outlet opening in a wall of the inner housing along a length of the inner housing, the inner housing having a reservoir of fragrance liquid on one end and a wick extending from the reservoir towards the other end of the inner housing which wicks fragrance liquid from the reservoir along a length of the wick, and
• the inner housing having an internally threaded collar on the one end and the reservoir having a matingly externally threaded collar on an end thereof, whereby the reservoir is threaded onto the inner housing,
• whereby air enters the at least one inlet opening of the outer housing and then enters the at least one inlet opening of the inner housing, the air carrying fragrance from the wick exiting the inner housing through the at least one outlet opening in the inner housing and exiting the outer housing through the at least one outlet opening of the outer housing, the air carrying the fragrance then entering the plenum or ductwork, and
• whereby the amount of fragrance released into the plenum or ductwork is adjusted by rotating the inner housing relative to the outer housing so as to partially or completely alien the at least one inlet opening of the inner housing with the at least one inlet opening of the outer housing and the at least one outlet opening of the inner housing with the at least one outlet opening in the outer housing.
