I picked up an Ozone machine fro Pros Choice and have been using it a little on some cigarette odors in vacant apartments and I am wondering how other cleaners charge for this? Do you figure out how many hours you need it to run and have an hourly rate in your head? Or is it just charge it for the use whether it runs for 10 hours or 20 hours? And is there any type of maintenance that needs to be done on these machines after so many hours of running?
