See full text

A method of cleaning an HVAC coil unit located above a drain basin. One step of the method involves providing a supply and collection assembly having a reservoir containing liquid cleaning solution, a pump operative to output the liquid cleaning solution through a supply outlet, and a vacuum source operative to draw in used liquid cleaning solution through a collection inlet. According to another step, a nozzle device in fluid communication with the supply outlet is also provided, the nozzle device having a delivery face. A further step involves providing a fluid return tool in fluid communication with the collection inlet, and positioning the fluid return tool in the drain basin. According to a further step, the delivery face of the nozzle device is moved across a surface of the HVAC coil unit to deliver the cleaning solution into areas between fins thereof.
