The present invention is directed to systems and methods for cleaning a component inside a machine, such as an evaporator coil inside an air conditioner. A pump is connected to a controlling device. The pump is also connected to a metering device. The metering device is connected to one or more reservoirs. The metering device is also connected to one or more wands. Each wand is positioned inside a housing containing the component to spray cleaning solution, drawn from the reservoirs by the metering device, onto a face of the component. To perform the cleaning of the component, the controlling device disables the machine. The controlling device then activates the pump. The pump causes cleaning solution to be drawn from the one or more reservoirs into the metering device, which then transfers the cleaning solution into the wands. The controlling device then allows the machine to resume operation.
