Recorded photos and filter sizes for (15) Roof units where roof was accessible by my own ladder. There are (47) Rooftop units by my count (assuming there is 1 at the Citizens bank and 6 on the tallest section above where the Popeyes will be) I could not access that part of the roof so there may be 2 more. There was way too much traffic to set up ladder to get a close look at citizens bank roof. * Very important; Determine lockbock location for mounted ladder access
