How would you clean HVAC diffusers? Can you power wash? We have 500 to clean. What would you charge?


You have two options, clean in place or remove, clean and reinstall. If you can fairly easily remove them and take them outside the building, you can use a pressure washer or ultra-sonic cleaning system. What is involved in taking them down and replacing them? The other option is to clean them in place, but the effectiveness of that depends on them being a style that allows easy wiping and or brushing. If you have a lot of small slots and bars, the time will be prohibitive. Also how dirty are they? Your best approach is to see what method is most effective and fastest, do a few while timing the operation, and then you will know what to price them per unit based on how long it takes to do the work and how many there are to be done.
