Systems and methods for cleaning a component inside an air handling apparatus includes a pump is connected to a controlling device and a metering device that is connected to one or more reservoirs. The metering device is also connected to one or more fogging devices. Each fogging device is positioned inside a housing, or plenum, so as to cause a fogged cleaning solution to be disbursed throughout the plenum and fully cover the component. To perform the cleaning of the component, the controlling device disables the machine and activates the pump which causes cleaning solution to be drawn from the one or more reservoirs into the metering device, which then transfers the cleaning solution into the fogging apparatus. The controlling device then allows the machine to resume operation.
