Apparatus for cleaning and remediating environmental air handling apparatus

Apparatus for cleaning an evaporator coil housed in a plenum of an air conditioner comprising:

• (a) at least one reservoir adapted to hold a substance that can be used to remediate said evaporator coil;
• (b) a pump configured to draw a metered amount of a substance from said at least one reservoir;
• (c) at least one fogging device located within said plenum wherein said evaporator coil is located, said at least one fogging device being configured to cause a fog of said substance to be formed within said plenum;
• (d) a controller configured to control the operation of said air conditioner, said pump, and said at least one fogging device, whereby said controller is configured to prevent operation of said air conditioner, to cause said pump to transfer said substance from said at least one reservoir to said at least one fogging device while operation of said air conditioner has been stopped, and to cause said at least one fogging device located within said plenum wherein said evaporator coil is located to cause a fog of said substance to be formed within said plenum, whereby a fog whose mean particle size is less than 50 microns will be produced that completely engulfs said evaporator coil as well as adjacent surfaces, after which said controller is adapted to resume operation of said air conditioner.
