Great Video - Great Info Any advice on cleaning the LOWER units? (i.e. the bottom side inside the buildings that people can see when looking up) - In an area where Dust and Pollen are very heavy and the lower units interiors and exteriors develop a nasty and gross black & greenish sticky sludge. The exterior of the units are somewhat easy to clean but what about the INSIDE of these lower units? Any hints?
That is a great question. There is one big difference. Make-up air does not have any A/C components. The system will be more elongated and not square. I would recommend checking out: ccpia.org/inspecting-commercial-kitchen-exhaust/ for more details.
